HEAD
0.8.1 - 2018-07-16
Note: This release does not change library behavior. It only corrects issues
in the installer and test system.
- Test Suite: Adjust test suite to match behavior introduced in 0.8.0. Thank
you Gianfranco Costamagna for reporting and a patch. #731
- CMake: Update cmake installer to only install library files globally.
Thank you Gianfraco Costamanga for reporting and a patch. #732
0.8.0 - 2018-07-12
- Examples: Add `print_client` example. This demonstrates a minimal non-TLS
client that connects to a server and prints out the messages it receives.
- Examples: Add `print_client_tls` example. This demonstrates a minimal TLS
client, including basic support via Asio+OpenSSL for certificate chain
and hostname verification.
- Feature: Add getter for all headers to the HTTP parsers. This allows a
wrapping library to enumerate all headers to send upstream. Thank you Jupp
Müller for reporting and an initial pull request.
- Improvement: Move the `socket_init_handler` to execute as a part of `init_asio`
rather than connection `pre_init`. This allows setting of socket options prior
to the bind/listen/accept system calls. Thank you ChristianRobl3D for
reporting #530.
- Improvement: Timers in transport integration tests should only fail if their
own test times out, rather than any test. #643 Thank you Alex Korotkin for
reporting and a patch.
- Improvement: Preserve transport layer error codes in more cases, particularly
during calls to `endpoint::listen`. #652 Thank you vadz for reporting and
patches.
- Compatibility: Make sure the chrono library used by Boost/Asio is in sync
with what the websocketpp is using. Thank you Flow86 for reporting and a
patch.
- Compatibility: Update `telemetry_client` to use a slightly more cross platform
method of sleeping. Should work on windows now. Thank you Meir Yanovich for
reporting.
- Compatibility: Updated permessage-deflate support to reflect that the zlib
library does not actually support a sliding window size of 256 bits.
WebSocket++ will no longer negotiate 256 bit deflate windows. If the user
of the library tries to request a 256 bit window a 512 bit window will be
specified instead (This was the previous behavior). #596 #653 Thank you
Vinnie Falco and Gianfranco Costamagna for reporting.
- Compatibility: Better error handling and logging in cases where extension
requests parse correctly but negotiation fails.
- Compatibility: Removed custom handling of `SSL_R_SHORT_READ` error condition.
This error code no longer exists in modern versions of OpenSSL and causes
a build error. It wasn't being used for anything particularly important
(slightly improving error reporting) and there isn't a great replacement.
#599 Thank you Gianfranco Costamagna for reporting.
- Compatibility: Add missing `<stdint>` headers. Fixes issues with g++ 5.4.0.
#638 Thank you Alex Korotkin for reporting and a patch.
- Compatibility: Remove the use of `std::auto_ptr` and `std::binary_function`
from builds with C++11 or later. These features are deprecated and were
removed entirely in C++17. This change allows building WebSocket++ on
C++17 compilers. #592 Thank you Michal Fojtak for reporting and a patch
- Compatibility: Add 1014 close code and adds missing descriptions for codes
1012 and 1013. #589 Thank you jbwdevries and ronneke1996 for reporting and
patches.
- Compatibility: Add hooks to support `mingw-std-threads` C++11 thread and mutex
polyfill library as an alternative to Boost. #608 Thank you Peter Taylor for
reporting and an initial patch.
- Compatibility: Changed the handshake connection token to 'Upgrade' from
'upgrade'. Technically this header is supposed to be processed case
insensitively. In practice, there are browsers (such as Edge) that don't do
this and they tend to use the uppercase value used as an example in RFC6455.
Thank you Johann Bauer for reporting and a patch. #727
- Bug: Store loggers in shared pointers to avoid crashes related to connections
trying to write logs entries after their respective endpoint has been
deallocated. Thank you Thalhammer for reporting and Jupp Müller for the
patch. #539 #501
- Bug: Change default listen backlog from 0 to `socket_base::max_connections`.
#549. Thank you derwassi and zwelab for reporting and na1pir for providing
access to hardware to debug the issue.
- Bug: Fix a crash in the accept loop when `get_connection` fails. #551 Thank you
Walter Gray for a patch.
- Bug/Documentation: Fix incorrect example code that used
`websocketpp::lib::error_code` instead of `websocketpp::exception`. Thank you
heretic13 for reporting
- Bug: Fix uninitialized shared pointer in Asio transport test suite. #647
Thank you Alex Korotkin for reporting and a patch.
- Bug: Fix a thread safety issue in the permessage-deflate extension that
caused message corruption when sending compressed messages from a different
thread than the main I/O thread. #615 Thank you KyleNyenhuis and Pieter De
Gendt for reporting and a patch.
- Bug: Fix an undefined behavior issue performing a 64 bit wide shift on a 64
bit value. #636 Thank you Gregor Jasny for reporting and a patch
- Bug: Fix some compile issues with ASIO_STANDALONE. #662 #665 Thank you
chronoxor and Guillaume Egles for reporting and patches.
0.7.0 - 2016-02-22
- MINOR BREAKING SOCKET POLICY CHANGE: Asio transport socket policy method
`cancel_socket` will now return `lib::asio::error_code` instead of `void`.
Custom Asio transport socket policies will need to be updated accordingly.
This does not affect anyone using the bundled socket policies.
- Feature: Basic support for the permessage-deflate extension. #344
- Feature: Allow accessing the local endpoint when using the Asio transport.
This allows inspection of the address and port in cases where they are chosen
by the operating system rather than the user. Thank you Andreas Weis and
Muzahid Hussain for reporting and related code. #458
- Feature: Add support for subprotocols in Hybi00. Thank you Lukas Obermann
for reporting and a patch. #518
- Feature: Adds `tcp_pre_bind handler` to Asio transport. This allows setting
arbitrary socket options after the listen acceptor has been created but before
the socket bind has been performed. #634 #439 Thank you Gregor Jasny for
the patch.
- Improvement: Better automatic std::chrono feature detection for Visual Studio
- Improvement: Major refactoring to bundled CMake build system. CMake can now be
used to build all of the examples and the test suite. Thank you Thijs Wenker
for a significant portion of this code. #378, #435, #449
- Improvement: In build environments where `lib::error_code` and
`lib::asio::error_code` match (such as using `boost::asio` with
`boost::system_error` or standalone asio with `std::system_error`, transport
errors are passed through natively rather than being reported as a translated
`pass_through` error type.
- Improvement: Add a `get_transport_error` method to Asio transport connections
to allow retrieving a machine readable native transport error.
- Improvement: Add `connection::get_response`, `connection::get_response_code`,
and `connection::get_response_msg` methods to allow accessing additional
information about the HTTP responses that WebSocket++ sends. #465 Thank you
Flow86 for reporting.
- Improvement: Removes use of empty strings ("") in favor of `string::clear()`
and `string::empty()`. This avoids generating unnecessary temporary objects.
#468 Thank you Vladislav Yaroslavlev for reporting and a patch.
- Documentation: Adds an example demonstrating the use of external `io_service`
- Documentation: Adds a simple `echo_client` example.
- Documentation: Begins migration of the web based user manual into Doxygen.
- Bug: Fix memory leak when `init_asio` produces an error. #454 Thank you Mark
Grimes for reporting and fixing.
- Bug: Fix crash when processing a specially crafted HTTP header. Thank you Eli
Fidler for reporting, test cases, and a patch. #456
- Bug: Fix an issue where standalone Asio builds that use TLS would not compile
due to lingering boost code. #448 Thank you mjsp for reporting
- Bug: Fix an issue where canceling a socket could throw an exception on some
older Windows XP platforms. It now prints an appropriate set of log messages
instead. Thank you Thijs Wenker for reporting and researching solutions. #460
- Bug: Fix an issue where deferred HTTP connections that start sending a very
long response before their HTTP handler ends would result in a second set of
HTTP headers being injected into the output. Thank you Kevin Smith for
reporting and providing test case details. #443
- Bug: Fix an issue where the wrong type of strand was being created. Thank you
Bastien Brunnenstein for reporting and a patch. #462
- Bug: Fix an issue where TLS includes were broken for Asio Standalone builds.
Thank you giachi and Bastien Brunnenstein for reporting. #491
- Bug: Remove the use of cached read and write handlers in the Asio transport.
This feature caused memory leaks when the `io_service` the connection was
running on was abruptly stopped. There isn't a clean and safe way of using
this optimization without global state and the associated locks. The locks
perform worse. Thank you Xavier Gibert for reporting, test cases, and code.
Fixes #490.
- Bug: Fix a heap buffer overflow when checking very short URIs. Thank you
Xavier Gibert for reporting and a patch #524
- Compatibility: Fixes a number of build & config issues on Visual Studio 2015
- Compatibility: Removes non-standards compliant masking behavior. #395, #469
- Compatibility: Replace deprecated use of `auto_ptr` on systems where
`unique_ptr` is available.
0.6.0 - 2015-06-02
- MINOR BREAKING TRANSPORT POLICY CHANGE: Custom transport policies will now be
required to include a new method `void set_uri(uri_ptr u)`. An implementation
is not required. The stub transport policy includes an example stub method
that can be added to any existing custom transport policy to fulfill this
requirement. This does not affect anyone using the bundled transports or
configs.
- MINOR BREAKING SOCKET POLICY CHANGE: Custom asio transport socket policies
will now be required to include a new method `void set_uri(uri_ptr u)`. Like
with the transport layer, an implementation is not required. This does not
affect anyone using the bundled socket policies.
- MINOR BREAKING DEPENDENCY CHANGE: When using Boost versions greater than or
equal to 1.49 in C++03 mode, `libboost-chrono` is needed now instead of
`libboost-date_time`. Users with C++11 compilers or using Boost versions 1.48
and earlier are not affected. Note: This change affects the bundled unit test
suite.
- Feature: WebSocket++ Asio transport policy can now be used with the standalone
version of Asio (1.8.0+) when a C++11 compiler and standard library are
present. This means that it is possible now to use WebSocket++'s Asio
transport entirely without Boost. Thank you Robert Seiler for proof of concept
code that was used as a guide for this implementation. Fixes #324
- Feature: Adds a vectored/scatter-gather write handler to the iostream
transport.
- Feature: Adds the ability to defer sending an HTTP response until sometime
after the `http_handler` is run. This allows processing of long running http
handlers to defer their response until it is ready without blocking the
network thread. references #425
- Improvement: `echo_server_tls` has been update to demonstrate how to configure
it for Mozilla's recommended intermediate and modern TLS security profiles.
- Improvement: `endpoint::set_timer` now uses a steady clock provided by
`boost::chrono` or `std::chrono` where available instead of the non-monotonic
system clock. Thank you breyed for reporting. fixes #241
- Improvement: Outgoing TLS connections to servers using the SNI extension to
choose a certificate will now work. Thank you moozzyk for reporting.
Fixes #400
- Improvement: Removes an unnecessary mutex lock in `get_con_from_hdl`.
- Cleanup: Asio transport policy has been refactored to remove many Boost
dependencies. On C++03 compilers the `boost::noncopyable` dependency has been
removed and the `boost::date_time` dependency has been replaced with the newer
`boost::chrono` when possible. On C++11 compilers the `boost::aligned_storage`
and `boost::date_time` dependencies are gone, replaced with equivalent C++11
standard library features.
- Bug: Fixes a potential dangling pointer and inconsistent error message
handling in `websocketpp::exception`. #432 Thank you Tom Swirly for the fix.
0.5.1 - 2015-02-27
- Bug: Fixes an issue where some frame data was counted against the max header
size limit, resulting in connections that included a lot of frame data
immediately after the opening handshake to fail.
- Bug: Fix a typo in the name of the set method for `max_http_body_size`. #406
Thank you jplatte for reporting.
0.5.0 - 2015-01-22
- BREAKING UTILITY CHANGE: Deprecated methods `http::parser::parse_headers`,
`http::response::parse_complete`, and `http::request::parse_complete` have
been removed.
- Security: Disabled SSLv3 in example servers.
- Feature: Adds basic support for accessing HTTP request bodies in the http
handler. #181
- Feature: Adds the ability to register a shutdown handler when using the
iostream transport. This provides a clean interface for triggering the shut
down of external sockets and other cleanup without hooking in to higher level
WebSocket handlers.
- Feature: Adds the ability to register a write handler when using the iostream
transport. This handler can be used to handle transport output in place of
registering an ostream to write to.
- Feature: Adds a new logging policy that outputs to syslog. #386 Thank you Tom
Hughes for submitting the initial version of this policy.
- Improvement: Message payload logging now prints text for text messages rather
than binary.
- Improvement: Overhaul of handshake state machine. Should make it impossible
for exceptions to bubble out of transport methods like `io_service::run`.
- Improvement: Overhaul of handshake error reporting. Fail handler error codes
will be more detailed and precise. Adds new [fail] and [http] logging channels
that log failed websocket connections and successful HTTP connections
respectively. A new aggregate channel package, `alevel::access_core`, allows
enabling connect, disconnect, fail, and http together. Successful HTTP
connections will no longer trigger a fail handler.
- Improvement: Ability to terminate connection during an http handler to cleanly
suppress the default outgoing HTTP response.
- Documentation: Add Sending & Receiving Messages step to chapter one of the
`utility_client` tutorial. Update `utility_client` example to match.
- Cleanup: Removes unused files & STL includes. Adds required STL includes.
Normalizes include order.
- Bug: Fixes a fatal state error when a handshake response is completed
immediately after that handshake times out. #389
- Bug: MinGW fixes; C++11 feature detection, localtime use. #393 Thank you
Schebb for reporting, code, and testing.
- Bug: Fixes an issue where `websocketpp::exception::what()` could return an out
of scope pointer. #397 Thank you fabioang for reporting.
- Bug: Fixes an issue where endpoints were not reset properly after a call to
`endpoint::listen` failed. #390 Thank you wyyqyl for reporting.
0.4.0 - 2014-11-04
- BREAKING API CHANGE: All WebSocket++ methods now throw an exception of type
`websocketpp::exception` which derives from `std::exception`. This normalizes
all exception types under the standard exception hierarchy and allows
WebSocket++ exceptions to be caught in the same statement as others. The error
code that was previously thrown is wrapped in the exception object and can be
accessed via the `websocketpp::exception::code()` method.
- BREAKING API CHANGE: Custom logging policies have some new required
constructors that take generic config settings rather than pointers to
std::ostreams. This allows writing logging policies that do not involve the
use of std::ostream. This does not affect anyone using the built in logging
policies.
- BREAKING UTILITY CHANGE: `websocketpp::lib::net::htonll` and
`websocketpp::lib::net::ntohll` have been prefixed with an underscore to avoid
conflicts with similarly named macros in some operating systems. If you are
using the WebSocket++ provided 64 bit host/network byte order functions you
will need to switch to the prefixed versions.
- BREAKING UTILITY CHANGE: The signature of `base64_encode` has changed from
`websocketpp::base64_encode(unsigned char const *, unsigned int)` to
`websocketpp::base64_encode(unsigned char const *, size_t)`.
- BREAKING UTILITY CHANGE: The signature of `sha1::calc` has changed from
`websocketpp::sha1::calc(void const *, int, unsigned char *)` to
`websocketpp::sha1::calc(void const *, size_t, unsigned char *)`
- Feature: Adds incomplete `minimal_server` and `minimal_client` configs that
can be used to build custom configs without pulling in the dependencies of
`core` or `core_client`. These configs will offer a stable base config to
future-proof custom configs.
- Improvement: Core library no longer has std::iostream as a dependency.
std::iostream is still required for the optional iostream logging policy and
iostream transport.
- Bug: C++11 Chrono support was being incorrectly detected by the `boost_config`
header. Thank you Max Dmitrichenko for reporting and a patch.
- Bug: use of `std::put_time` is now guarded by a unique flag rather than a
chrono library flag. Thank you Max Dmitrichenko for reporting.
- Bug: Fixes non-thread safe use of std::localtime. #347 #383
- Compatibility: Adjust usage of std::min to be more compatible with systems
that define a min(...) macro.
- Compatibility: Removes unused parameters from all library, test, and example
code. This assists with those developing with -Werror and -Wunused-parameter
#376
- Compatibility: Renames ntohll and htonll methods to avoid conflicts with
platform specific macros. #358 #381, #382 Thank you logotype, unphased,
svendjo
- Cleanup: Removes unused functions, fixes variable shadow warnings, normalizes
all whitespace in library, examples, and tests to 4 spaces. #376
0.3.0 - 2014-08-10
- Feature: Adds `start_perpetual` and `stop_perpetual` methods to asio transport
These may be used to replace manually managed `asio::io_service::work` objects
- Feature: Allow setting pong and handshake timeouts at runtime.
- Feature: Allows changing the listen backlog queue length.
- Feature: Split tcp init into pre and post init.
- Feature: Adds URI method to extract query string from URI. Thank you Banaan
for code. #298
- Feature: Adds a compile time switch to asio transport config to disable
certain multithreading features (some locks, asio strands)
- Feature: Adds the ability to pause reading on a connection. Paused connections
will not read more data from their socket, allowing TCP flow control to work
without blocking the main thread.
- Feature: Adds the ability to specify whether or not to use the `SO_REUSEADDR`
TCP socket option. The default for this value has been changed from `true` to
`false`.
- Feature: Adds the ability to specify a maximum message size.
- Feature: Adds `close::status::get_string(...)` method to look up a human
readable string given a close code value.
- Feature: Adds `connection::read_all(...)` method to iostream transport as a
convenience method for reading all data into the connection buffer without the
end user needing to manually loop on `read_some`.
- Improvement: Open, close, and pong timeouts can be disabled entirely by
setting their duration to 0.
- Improvement: Numerous performance improvements. Including: tuned default
buffer sizes based on profiling, caching of handler binding for async
reads/writes, non-malloc allocators for read/write handlers, disabling of a
number of questionably useful range sanity checks in tight inner loops.
- Improvement: Cleaned up the handling of TLS related errors. TLS errors will
now be reported with more detail on the info channel rather than all being
`tls_short_read` or `pass_through`. In addition, many cases where a TLS short
read was in fact expected are no longer classified as errors. Expected TLS
short reads and quasi-expected socket shutdown related errors will no longer
be reported as unclean WebSocket shutdowns to the application. Information
about them will remain in the info error channel for debugging purposes.
- Improvement: `start_accept` and `listen` errors are now reported to the caller
either via an exception or an ec parameter.
- Improvement: Outgoing writes are now batched for improved message throughput
and reduced system call and TCP frame overhead.
- Bug: Fix some cases of calls to empty lib::function objects.
- Bug: Fix memory leak of connection objects due to cached handlers holding on to
reference counted pointers. #310 Thank you otaras for reporting.
- Bug: Fix issue with const endpoint accessors (such as `get_user_agent`) not
compiling due to non-const mutex use. #292 Thank you logofive for reporting.
- Bug: Fix handler allocation crash with multithreaded `io_service`.
- Bug: Fixes incorrect whitespace handling in header parsing. #301 Thank you
Wolfram Schroers for reporting
- Bug: Fix a crash when parsing empty HTTP headers. Thank you Thingol for
reporting.
- Bug: Fix a crash following use of the `stop_listening` function. Thank you
Thingol for reporting.
- Bug: Fix use of variable names that shadow function parameters. The library
should compile cleanly with -Wshadow now. Thank you giszo for reporting. #318
- Bug: Fix an issue where `set_open_handshake_timeout` was ignored by server
code. Thank you Robin Rowe for reporting.
- Bug: Fix an issue where custom timeout values weren't being propagated from
endpoints to new connections.
- Bug: Fix a number of memory leaks related to server connection failures. #323
#333 #334 #335 Thank you droppy and aydany for reporting and patches.
reporting.
- Compatibility: Fix compile time conflict with Visual Studio's MIN/MAX macros.
Thank you Robin Rowe for reporting.
- Documentation: Examples and test suite build system now defaults to clang on
OS X
0.3.0-alpha4 - 2013-10-11

for reporting. #294
- Eliminates spurious expired timers in certain error conditions. Thank you
Banaan for reporting. #295
- Consolidates all bundled library licenses into the COPYING file. #294
- Updates bundled sha1 library to one with a cleaner interface and more
straight-forward license. Thank you lotodore for reporting and Evgeni Golov
for reviewing. #294
- Re-introduces strands to asio transport, allowing `io_service` thread pools to
be used (with some limitations).
- Removes endpoint code that kept track of a connection list that was never used
anywhere. Removes a lock and reduces connection creation/deletion complexity
from O(log n) to O(1) in the number of connections.
- A number of internal changes to transport APIs
- Deprecates iostream transport `readsome` in favor of `read_some` which is more
consistent with the naming of the rest of the library.
- Adds preliminary signaling to iostream transport of eof and fatal transport
errors
- Updates transport code to use shared pointers rather than raw pointers to
prevent asio from retaining pointers to connection methods after the
connection goes out of scope. #293 Thank you otaras for reporting.
- Fixes an issue where custom headers couldn't be set for client connections
Thank you Jerry Win and Wolfram Schroers for reporting.
- Fixes a compile error on visual studio when using interrupts. Thank you Javier
Rey Neira for reporting this.
- Adds new 1012 and 1013 close codes per IANA registry
- Add `set_remote_endpoint` method to iostream transport.
- Add `set_secure` method to iostream transport.
- Fix typo in .gitattributes file. Thank you jstarasov for reporting this. #280
- Add missing locale include. Thank you Toninoso for reporting this. #281
- Refactors `asio_transport` endpoint and adds full documentation and exception
free varients of all methods.
- Removes `asio_transport` endpoint method cancel(). Use `stop_listen()` instead
- Wrap internal `io_service` `run_one()` method
- Suppress error when trying to shut down a connection that was already closed

- Minor refactor to bundled sha1 library
- HTTP header comparisons are now case insensitive. #220, #275
- Refactors URI to be exception free and not use regular expressions. This
eliminates the dependency on boost or C++11 regex libraries allowing native
C++11 usage on GCC 4.4 and higher and significantly reduces staticly built
binary sizes.
- Updates handling of Server and User-Agent headers to better handle custom
settings and allow suppression of these headers for security purposes.
- Fix issue where pong timeout handler always fired. Thank you Steven Klassen
for reporting this bug.
- Add ping and pong endpoint wrapper methods
- Add `get_request()` pass through method to connection to allow calling methods
specific to the HTTP policy in use.
- Fix issue compile error with `WEBSOCKETPP_STRICT_MASKING` enabled and another
issue where `WEBSOCKETPP_STRICT_MASKING` was not applied to incoming messages.
Thank you Petter Norby for reporting and testing these bugs. #264
- Add additional macro guards for use with boost_config. Thank you breyed
for testing and code. #261
0.3.0-alpha2 - 2013-06-09
- Fix a regression that caused servers being sent two close frames in a row
to end a connection uncleanly. #259
- Fix a regression that caused spurious frames following a legitimate close
frames to erroneously trigger handlers. #258
- Change default HTTP response error code when no http_handler is defined from
500/Internal Server Error to 426/Upgrade Required

/** \page reference.config Config Reference
WebSocket++ uses a config template parameter to supply a number of compile type policy types and default numerical values for buffer sizes, timeouts, security behavior, etc. Swapping policies allows changing certain core library behavior designed to be pluggable.
A custom config can be made standalone or can subclass one of the bundled configs and just override a few things.
__Example__
```
// some config options may require additional includes or dependencies.
// syslog logging policy, for example, requires <syslog.h>,
// the permessage deflate settings require zlib.
#include <websocketpp/logger/syslog.hpp>
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
// Custom server config based on bundled asio config
struct custom_server_config : public websocketpp::config::asio {
// Replace default stream logger with a syslog logger
typedef websocketpp::log::syslog<concurrency_type, websocketpp::log::elevel> elog_type;
typedef websocketpp::log::syslog<concurrency_type, websocketpp::log::alevel> alog_type;
// Reduce read buffer size to optimize for small messages
static const size_t connection_read_buffer_size = 1024;
// enable permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::server<custom_server_config> server_endpoint_type;
```
Core Config Options
-------------------
### Policies
Policies are classes used to allow clean swapping of behavior without changing the core library
| Typedef Name | Effect |
| ------------------------- | -------------------------------------- |
| concurrency_type | Concurrency policy |
| elog_type | Error logger type |
| alog_type | Access logger type |
| request_type | HTTP request type |
| response_type | HTTP response type |
| message_type | Type to deliver recieved messages |
| con_msg_manager_type | Connection level message manager |
| endpoint_msg_manager_type | Endpoint level message manager |
| rng_type | Random Number Generation policy |
| transport_type | Transport policy to use |
| endpoint_base | User overridable Endpoint base class |
| connection_base | User overridable Connection base class |
### Timeouts Values
These represent the length of time (in ms) before the given operation is aborted
| Field | Type | Default | Operation |
| ----------------------- | ---- | ------- | --------------------------- |
| timeout_open_handshake | long | 5000 | Opening handshake |
| timeout_close_handshake | long | 5000 | Closing handshake |
| timeout_pong | long | 5000 | No pong recieved after ping |
### Performance tuning
| Field | Type | Default | Meaning |
| --------------------------- | ------ | -------- | ------------------------------------------------------------------ |
| connection_read_buffer_size | size_t | 16384 | Size of the per-connection read buffer |
| enable_multithreading | bool | true | Disabling may reduce locking overhead for single threaded programs |
#### Connection Read Buffer
Each connection has an internal buffer of this size. A larger value will result in fewer trips through the library and less CPU overhead at the expense of increased memory usage per connection.
If your application primarily deals in very large messages you may want to try setting this value higher.
If your application has a lot of connections or primarily deals in small messages you may want to try setting this smaller.
### Security settings
| Field | Type | Default | Effect |

| drop_on_protocol_error | bool | false | Omit close handshake on protocol error |
| silent_close | bool | false | Don't return close codes or reasons |
| max_message_size | size_t | 32MB | WebSocket max message size limit |
| max_http_body_size | size_t | 32MB | HTTP Parser's max body size limit |
#### Drop on protocol error
Drop connections on protocol error rather than sending a close frame. Off by default. This may result in legitimate messages near the error being dropped as well. It may free up resources otherwise spent dealing with misbehaving clients.
#### Silent Close
Silence close suppresses the return of detailed connection close information during the closing handshake. This information is useful for debugging and presenting useful errors to end users but may be undesirable for security reasons in some production environments. Close reasons could be used by an attacker to confirm that the endpoint is out of resources or be used to identify the WebSocket implementation in use.
Note: this will suppress *all* close codes, including those explicitly sent by local applications.
#### Max message size
Default value for the processor's maximum message size. Maximum message size determines the point at which the library will drop a connection with the message_too_big protocol error.
#### Max HTTP header size
Maximum body size determines the point at which the library will abort reading an HTTP message body and return the 413/request entity too large error.

/** \page faq FAQ
## General Library Usage
### Can a handler be changed after a connection is established? Can one be removed?
Yes, but not globally.
Handlers assigned to endpoints will be automatically copied to the connections created by that endpoint. Changing a handler on an endpoint will only affect future connections.
Once a particular connection is created, it's handlers can be changed individually by calling the `set_*_handler` methods. Once changed, all future events of that type for that connection will use the new handler.
To remove a handler that was previously set, call the set method with `nullptr` or `NULL`.
### Can I reject or conditionally accept a connection
Yes. The `validate` handler is called after the initial handshake has been recieved but before WebSocket++ has responded. This gives you the opportunity to inspect the incoming connection request, its headers, origin, subprotocols, and the remote endpoint IP. Return `true` from the validate handler to accept the connection and `false` to reject it.
To set a custom HTTP error message for your rejection, use `websocketpp::connection::set_status` and (optionally) `websocketpp::connection::set_body()` to set the HTTP status code and error message body text. If you do not set body text a message will be generated automatically based on the status code.
### How do I negotiate subprotocols?
WebSocket connections may offer a particular subprotocol they want to use. The WebSocket protocol does not define the meaning or interpretation of the subprotocol. This interpretation is left up to the individual application endpoints.
WebSocket++ servers can read the requested subprotocols during the `validate` handler by calling `websocketpp::connection::get_requested_subprotocols`. The list is ordered by client priority. You may optionally choose one of these subprotocols with `websocketpp::connection::select_subprotocol`. The handshake will then complete and let the client know which one was chosen. If you do not choose any, the "blank"/empty/none subprotocol will be used.
WebSocket++ clients can add a subprotocol to an outgoing connection by calling `websocketpp::connection::add_subprotocol` before calling `websocketpp::client::connect`. The order of adding will be interpreted as the order of preference.
In both caases, after the connection has been established, the selected subprotocol is available via the `websocketpp::connection::get_subprotocol` method.
Note: some browsers will allow the connection to continue if they requested a subprotocol and your server doesn't select one. Others will reject the connection.
### How do I cleanly exit an Asio transport based program
The Asio transport based clients and servers use the Asio library's underlying `io_service` to handle asyncronous networking operations. The standard behavior of the io_service is to run until there are no async operations left and then return. WebSocket++, when using the Asio transport, behaves like a standard Asio application. If you want your WebSocket++/Asio based program to stop network operations and cleanly close all sockets you will want to do the following:
- For servers, call `websocketpp::transport::asio::endpoint::stop_listening` to initiate the closing of the server listening socket.
- For clients, if you have engaged perpetual mode with `websocketpp::transport::asio::endpoint::start_perpetual`, disable it with `websocketpp::transport::asio::endpoint::stop_perpetual`.
- For both, run `websocketpp::endpoint::close` or `websocketpp::connection::close` on all currently outstanding connections. This will initiate the WebSocket closing handshake for these connections
- Wait. Asio is asyncronous. When the calls to the above methods (stop_listening, close, etc) complete the server *will still be listening*, the connections *will still be active* until the io_service gets around to asyncronously processing the socket and WebSocket protocol closing handshakes. The `io_service::run` method will exit cleanly and automatically when all operations are complete.
__WARNING__: Asio's `io_service` has a method called `stop`. WebSocket++ wraps this method as `websocketpp::transport::asio::endpoint::stop`. While this operation has a benign sounding name, it is a powerful and destructive operation that should only be used in special cases. If you are using `io_service::stop` or `endpoint::stop` without a very good reason your program is likely broken and may exhibit erratic behavior. Specifically, `io_service::stop` stops the processing of events entirely. This does not give current operations (such as socket closing handshakes) the opportunity to finish. It will leave your sockets in a dangling state that may invoke operating system level timeouts or other errors.
__Special cases__:
- If your client uses the `start_perpetual` method it will prevent the io_service from exiting even if it has nothing to do. This is useful if you want a client endpoint to idle in the background to allow new connections to be formed on demand rather than generating a new endpoint for each.
- If you are using an external io_service and/or are placing non-WebSocket++ operations on the `io_service` those operations may keep the `io_service` open even after all WebSocket++ operations have completed.
- If you are using `poll`/`poll_one`/`run_one` or otherwise manually driving the `io_service` event loop you may need to adjust usage to make sure you are correctly recognizing the "done with work" and "not done but idling / `io_service::work`" cases.
### Is there a way to check the validity of a `connection_hdl`?
Sometimes, not generally though, because there isn’t a way to check if a TCP connection is valid.
You can try upgrading your hdl to a full connection_ptr using `websocketpp::endpoint::get_con_from_hdl`. If this fails, the hdl is definitely invalid. If it succeeds it may or may not be. The only way to tell definitively is to try and send something (either a message or a ping).
If you handle errors from methods like send, ping, close, etc correctly then you shouldn’t have to worry about accidentally sending to dead connections. The send/ping/pong/close methods will set or throw a specific error in the case that you tried to send something but the connection was closed/gone/etc.
### How do I fix the "address is in use" error when trying to restart my server?
Normally, for security purposes, operating systems prevent programs from listening on sockets created by other programs. When your program crashes and restarts, the new instance is a different program from the perspective of the operating system. As such it can’t listen on the socket address/port that the previous program was using until after a timeout occurs to make sure the old program was done with it.
The the first step for handling this is to make sure that you provide a method (signal handler, admin websocket message, etc) to perform a clean server shutdown. There is a question elsewhere in this FAQ that describes the steps necessary for this.
The clean close strategy won't help in the case of crashes or other abnormal closures. An option to consider for these cases is the use of the SO_REUSEADDR socket option. This instructs the OS to not request an exclusive lock on the socket. This means that after your program crashes the replacement you start can immediately listen on that address/port combo again.
__Please note__: how this works exactly depends on your operating system. Additionally, not exclusively locking your listening socket could allow hijacking by other programs if you are running in a shared resource environment. For development this is generally no problem. For a production environment, think carefully about the security model. `websocketpp::transport::asio::endpoint::set_reuse_addr` is the method to do this. You must specify this setting before calling `websocketpp::transport::asio::endpoint::listen`.
### How do I send and recieve binary messages?
When supported by the remote endpoint, WebSocket++ allows reading and sending messages in the two formats specified in RFC6455, UTF8 text and binary. WebSocket++ performs UTF8 validation on all outgoing text messages to ensure that they meet the specification. Binary messages do not have any additional processing and their interpretation is left entirely to the library user.
To determine the type of an incoming message, use `websocketpp::message_buffer::message::get_opcode`. The relevant return values are `websocketpp::frame::opcode::text` and `websocketpp::frame::opcode::binary`. There is no difference in how payloads are retrieved between these modes, only in how WebSocket++ validated the contents and how the library user is to interpret the data.
To specify the type of an outgoing message, use the frame opcode values listed above as the second op parameter for `websocketpp::connection::send`. There are two relevant overloads of send. One that takes a `std::string` and defaults to op=text. The other that takes a `void const *` and a `size_t` length and defaults to op=binary. Note: You can send binary messages via the string overload and text messages via the void * overload. In the case that you are manually building a message buffer rather than using the automatic send member functions, you can pass the opcode in as a parameter to the message buffer constructor or user the `websocketpp::message_buffer::message::set_opcode` member function to set or re-set it later.
## Dependency Management
### Can WebSocket++ be used without Boost?
Yes. WebSocket++ only uses Boost features as polyfills for C++11 language features and libraries. If you have a C++11 compiler and standard library you can use WebSocket++ without Boost. In most cases setting your build environment to use the C++11 (or later) language dialect is sufficient to enable this mode of use.
With less common compilers (and sometimes very recently release compilers) there may be specific issues with certain libraries that aren't automatically detected by the library. For these situations there are additional defines available to fine tune which C++11 libraries and features are used. TODO: more details about them.
For the iostream/raw transport the C++11 standard library is sufficient. For the Asio based transports, there is no C++11 library that provides the networking capabilaties that Asio does. As such even with a C++11 build system, you will need a standalone copy of Asio to use if Boost Asio is not available.
MinGW users who want to avoid Boost should also consult the nearby question about MinGW compatibility.
### Can WebSocket++ be used with standalone Asio
Yes. The process is the same as used with standalone Asio itself. Define `ASIO_STANDALONE` before including Asio or WebSocket++ headers. You will need to download a copy of the Asio headers separately (http://www.think-async.com) and make sure they are in your build system's include path.
### Can WebSocket++ be used without TLS or OpenSSL?
Yes. When using the iostream/raw transport, there are no TLS features and OpenSSL is not required. When using the Asio transport TLS features are optional. You only need OpenSSL if you want to use TLS. You can only make or recieve encrypted connections (https/wss) if you have enabled TLS features.
Whether an Asio endpoint uses TLS or not is determined by its config template parameter. The default bundled `websocketpp::config::asio` and `websocketpp::config::asio_client` configs do not support TLS, the `websocketpp::config::asio_tls` and `websocketpp::config::asio_tls_client` do.
The `<websocketpp/config/asio.hpp>` and `<websocketpp/config/asio_client.hpp>` headers will include both the TLS and non-TLS varients of their respective configs and require the presence of OpenSSL. The `<websocketpp/config/asio_no_tls.hpp>` and `<websocketpp/config/asio_no_tls_client.hpp>` headers will include only the non-TLS configs and do not require OpenSSL.
### Build issues with TLS on recent versions of OS X
Mac OS X ships a severely outdated version of the OpenSSL library. To securely use TLS with WebSocket++ on OS X you will need to install a modern version of OpenSSL via homebrew or compiling from source.
### Can WebSocket++ be used with MinGW
Generally, yes. Note that in C++11 mode MinGW does not currently support the C++11 STL `<thread>` library. WebSocket++ requires a thread/mutex library. Options include Boost thread (the default when a compatible C++11 `<thread>` can't be found) or `mingw-std-threads` (https://github.com/meganz/mingw-std-threads) by including those headers and defining `_WEBSOCKETPP_MINGW_THREAD_`.
## Compression
### How do I use permessage-deflate in version 0.6.0-permessagedeflate and 0.7.0?
These versions of the library require a custom config to use the permessage-deflate extension. Here is a minimal example of such a custom config. You can also integrate these lines into an existing custom config.
Note that in these versions there is no fine grained control over which connections are compressed or not. Clients will request compression with the default settings and use it if the server supports it. Servers will accept whatever parameters clients request.
Outgoing messages by default will be compressed if compression was auto-negotiated during the handshake. There is an option to force a specific message to be sent uncompressed even if compression was negotiated. This may be useful for sending data that you know to be compressed already (images, zip files, etc).
__Server Example__
```
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
struct deflate_server_config : public websocketpp::config::asio {
// ... additional custom config if you need it for other things
/// permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::server<deflate_server_config> server_endpoint_type;
```
__Client Example__
```
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
struct deflate_client_config : public websocketpp::config::asio_client {
// ... additional custom config if you need it for other things
/// permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::client<deflate_client_config> client_endpoint_type;
```
## Security
### Is it possible to terminate a malicious connection quickly, without tying up resources performing clean close steps,
Yes. The library will automatically detect and terminate connections that violate the WebSocket protocol. In cases where the library believes the remote endpoint to be malicious or sufficiently broken to be unlikely to understand or process the closing handshake, it will be omited.
If your application detects conditions above the protocol level that you believe to be malicious, for example, if you recognize an IP from a known denial of service attack, you can close the connection with two different levels of urgency. Use the standard `websocketpp::endpoint::close` or `websocketpp::connection::close` methods with one of the following special close codes:
- `websocketpp::close::status::omit_handshake`: Omits the closing handshake, but cleanly closes the TCP connection.
- `websocketpp::close::status::force_tcp_drop`: Forcibly drop the TCP connection.
Please note that usage of these disconnect methods results in a violation of the WebSocket protocol and may have negative reprocusions for the remote endpoint with respect to network timeouts. Please use caution when using them.
## Build Issues
### Getting compile errors related to `std::chrono`, `boost::chrono`, `waitable_timer`, or `steady_clock`
Your build system may be confused about whether it is supposed to be using `boost::chrono` or `std::chrono`. Boost automatically detects this setup on some compilers but not others. Defining `BOOST_ASIO_HAS_STD_CHRONO` can help. See http://www.boost.org/doc/libs/1_60_0/doc/html/boost_asio/overview/cpp2011/chrono.html for more details.

/** \page reference.handlers Handler Reference
Handlers allow WebSocket++ programs to receive notifications about events
that happen in relation to their connections. Some handlers also behave as
hooks that give the program a chance to modify state or adjust settings before
the connection continues.
Handlers are registered by calling the appropriate `set_*_handler` method on either an
endpoint or connection. The * refers to the name of the handler (as
specified in the signature field below). For example, to set the open handler,
call `set_open_handler(...)`.
Setting handlers on an endpoint will result in them being copied as the default
handler to all new connections created by that endpoint. Changing an endpoint's
handlers will not affect connections that are already in progress. This includes
connections that are in the listening state. As such, it is important to set any
endpoint handlers before you call `endpoint::start_accept` or else the handlers
will not be attached to your first connection.
Setting handlers on a connection will result in the handler being changed for
that connection only, starting at the next time that handler is called. This can
be used to change the handler during a connection.
Connection Handlers
-------------------
These handlers will be called at most once per connection in the order specified below.
### Socket Init Handler
| Event | Signature | Availability |
| --------------------- | ----------------------------------------------------- | -------------------- |
| Socket initialization | `socket_init(connection_hdl, asio::ip::tcp::socket&)` | 0.3.0 Asio Transport |
This hook is triggered after the socket has been initialized but before a connection is established.
It allows setting arbitrary socket options before connections are sent/recieved.
### TCP Pre-init Handler
| Event | Signature | Availability |
| ----------------------------- | ------------------------------ | -------------------- |
| TCP established, no data sent | `tcp_pre_init(connection_hdl)` | 0.3.0 Asio Transport |
This hook is triggered after the TCP connection is established, but before any pre-WebSocket-handshake
operations have been run. Common pre-handshake operations include TLS handshakes and proxy connections.
### TCP Post-init Handler
| Event | Signature | Availability |
| ----------------------- | ------------------------------------------ | ----------------------------- |
| Request for TLS context | `tls_context_ptr tls_init(connection_hdl)` | 0.3.0 Asio Transport with TLS |
This hook is triggered before the TLS handshake to request the TLS context to use. You must
return a pointer to a configured TLS conext to continue. This provides the opportuinity to
set up the TLS settings, certificates, etc.
### Validate Handler
| Event | Signature | Availability |
| ------------------------------------- | ------------------------------- | ---------------------------- |
| Hook to accept or reject a connection | `bool validate(connection_hdl)` | 0.3.0 Core, Server role only |
This hook is triggered for servers during the opening handshake after the request has been
processed but before the response has been sent. It gives a program the opportunity to inspect
headers and other connection details and either accept or reject the connection. Validate happens
before the open or fail handler.
Return true to accept the connection, false to reject. If no validate handler is registered,
all connections will be accepted.
### Open Connection Handler
| Event | Signature | Availability |
| ------------------------- | ---------------------- | ------------ |
| Successful new connection | `open(connection_hdl)` | 0.3.0 Core |
Either open or fail will be called for each connection. Never both. All
connections that begin with an open handler call will also have a matching
close handler call when the connection ends.
### Fail Connection Handler
| Event | Signature | Availability |
| ----------------------------------- | ---------------------- | ------------ |
| Connection failed (before opening) | `fail(connection_hdl)` | 0.3.0 Core |
Either open or fail will be called for each connection. Never both. Connections
that fail will never have a close handler called.
### Close Connection Handler
| Event | Signature | Availability |
| --------------------------------- | ----------------------- | ------------ |
| Connection closed (after opening) | `close(connection_hdl)` | 0.3.0 Core |
Close will be called exactly once for every connection that open was called for.
Close is not called for failed connections.
Message Handlers
----------------
These handers are called in response to incoming messages or message like events. They only will be called while the connection is in the open state.
### Message Handler
| Event | Signature | Availability |
| --------------------- | -------------------------------------- | ------------ |
| Data message recieved | `message(connection_hdl, message_ptr)` | 0.3.0 Core |
Applies to all non-control messages, including both text and binary opcodes. The
`message_ptr` type and its API depends on your endpoint type and its config.
### Ping Handler
| Event | Signature | Availability |
| ------------- | ---------------------------------------- | ------------ |
| Ping recieved | `bool ping(connection_hdl, std::string)` | 0.3.0 Core |
Second (string) argument is the binary ping payload. Handler return value
indicates whether or not to respond to the ping with a pong. If no ping handler
is set, WebSocket++ will respond with a pong containing the same binary data as
the ping (Per requirements in RFC6455).
### Pong Handler
| Event | Signature | Availability |
| ------------- | ----------------------------------- | ------------ |
| Pong recieved | `pong(connection_hdl, std::string)` | 0.3.0 Core |
Second (string) argument is the binary pong payload.
### Pong Timeout Handler
| Event | Signature | Availability |
| ---------------------------------- | ------------------------------------------- | ---------------------------------------- |
| Timed out while waiting for a pong | `pong_timeout(connection_hdl, std::string)` | 0.3.0 Core, transport with timer support |
Triggered if there is no response to a ping after the configured duration. The second
(string) argument is the binary payload of the unanswered ping.
### HTTP Handler
| Event | Signature | Availability |
| --------------------- | --------------------- | ---------------------------- |
| HTTP request recieved | `http(connection_hdl` | 0.3.0 Core, Server role only |
Called when HTTP requests that are not WebSocket handshake upgrade requests are
recieved. Allows responding to regular HTTP requests. If no handler is registered
a 426/Upgrade Required error is returned.
### Interrupt Handler
| Event | Signature | Availability |
| ----------------------------------- | --------------------------- | ------------ |
| Connection was manually interrupted | `interrupt(connection_hdl)` | 0.3.0 Core |
Interrupt events can be triggered by calling `endpoint::interrupt` or `connection::interrupt`.
Interrupt is similar to a timer event with duration zero but with lower overhead. It is useful
for single threaded programs to allow breaking up a very long handler into multiple parts and
for multi threaded programs as a way for worker threads to signale to the main/network thread
that an event is ready.

/** \page reference.logging Logging Reference
WebSocket++ has the capability of logging events during the lifetime of the connections that it processes. Each endpoint has two independent logging interfaces that are used by all connections created by that endpoint. The first is an access interface that allows logging routine events in the life of a connection (such as connect/disconnect and receipt of messages). The other is an error interface that allows logging non-routine problems or errors. Each interface has a number of different named channels that can be toggled on and off independently.
Exactly how these logs are processed and where they are written to depends on which logging policy is in use. Several logging policies are included by default and you can write your own policy if you need something more specialized. Selecting a policy is done via the \subpage reference.config "endpoint config".
Common functionality (all policies)
-----------------------------------
### Logging Channels
Each logging interface is divided into 32 named channels. Log messages are written to a specific interface on a specific channel. Which log messages are actually printed is determined by which channels are enabled or not. Channels can be enabled or disabled either at compile time or at runtime.
### Enabling and Disabling Channels
Channels disabled at compile time are removed from the code entirely (assuming correct compiler optimization settings) and are not available for runtime enabling or disabling. To disable channels at compile time, use the `alog_level` and `elog_level` values within your \subpage reference.config "endpoint config". Channels not disabled at compile time can be enabled or disabled at runtime using the `websocketpp::endpoint::set_access_channels()`, `websocketpp::endpoint::clear_access_channels()`, `websocketpp::endpoint::set_error_channels()`, and `websocketpp::endpoint::clear_error_channels()` methods.
The set and clear functions act only on the channels specified. `set_access_channels(log::alevel::connect)` will enable logging of new connections. Following this with `set_access_channels(log::alevel::disconnect)` will enable logging of disconnections in addition to connections. Use `clear*` functions to disable a specific channel. Channels may be combined using bitwise operations to create aggregate packages of channels that may be set or cleared at once. Default packages include `websocketpp::log::alevel::all`, `websocketpp::log::elevel::all`, `websocketpp::log::alevel::none`, `websocketpp::log::elevel::none`. These represent all possible access/error channels and no access/error channels respectively. For convenience, setting none is aliased to clearing all.
### Examples
__Disable all__
`clear_access_channels(log::alevel::all)`
__Disable all (alternative method)__
`set_access_channels(log::alevel::none)`
__Multiple channels at once__
`log::alevel::message_payload | log::alevel::message_payload`
__All except one__
`log::alevel::all ^ log::alevel::message_payload`
__Default settings__
By default, only debug/development logging is disabled.
### Access to underlying loggers
Logging interfaces may be directly accessed via their associated endpoint or connection using get_alog() and get_elog(). This allows access to methods specific to the chosen logging policy.
Basic Logging (Default Policy)
------------------------------
The basic logging policy (`websocketpp::log::basic`) writes logs to a std::ostream. By default, access logs are written to stdout and error logs are written to stderr. Each logging interface may be optionally redirected to an arbitrary C++ stream (including file streams) using the `websocketpp::log::basic::set_ostream()` method.
Syslog Logging
--------------
The syslog logging policy (`websocketpp::log::syslog`) logs to POSIX syslog. It is included in the header `<websocketpp/logger/syslog.hpp>`. It requires a system with `<syslog.h>`.
Stub Logging
------------
The stub logging policy (`websocketpp::log::stub`) implements the logging policy interface but ignores all input and provides no output. It can be used to stub out the logging system in tests or to completely disable and remove nearly all logging related code.
The stub logger also provides documentation for the minimal required interface to build a custom logging policy.
Log level reference
-------------------
### Error Logging Levels
Each of these channels is in the namespace `websocketpp::log::elevel`
| Level | Description |
| ------- | -------------------------------------------------------------------------------------------------------------------------- |
| none | Special aggregate value representing "no levels" |
| devel | Low level debugging information (warning: very chatty). Requires debug or custom config. |
| library | Information about unusual system states or other minor internal library problems, less chatty than devel. |
| info | Information about minor configuration problems or additional information about other warnings. |
| warn | Information about important problems not severe enough to terminate connections. |
| rerror | Recoverable error. Recovery may mean cleanly closing the connection with an appropriate error code to the remote endpoint. |
| fatal | Unrecoverable error. This error will trigger immediate unclean termination of the connection or endpoint. |
| all | Special aggregate value representing "all levels" |
### Access Logging Levels
Each of these channels is in the namespace `websocketpp::log::alevel`
| Level | Description |
| --------------- | -------------------------------------------------------------------------------------------------- |
| none | Special aggregate value representing "no levels" |
| connect | One line for each new connection that includes a host of information including: the remote address, websocket version, requested resource, http code, remote user agent |
| disconnect | One line for each connection that is closed. Includes closing codes and reasons |
| control | One line per control message |
| frame_header | One line per frame, includes the full frame header |
| frame_payload | One line per frame, includes the full message payload (warning: lots of output for large messages) |
| message_header | Reserved |
| message_payload | Reserved |
| endpoint | Reserved |
| debug_handshake | Extra information about opening handshakes |
| debug_close | Extra information about closing handshakes |
| devel | Development messages (warning: very chatty). Requires debug or custom config. |
| app | Special channel for application specific logs. Not used by the library. |
| all | Special aggregate value representing "all levels" |

/** \mainpage
WebSocket++ is a C++ library that can be used to implement WebSocket functionality. The goals of the project are to provide a WebSocket implementation that is portable, flexible, lightweight, low level, and high performance.
WebSocket++ does not intend to be used alone as a web application framework or full featured web services platform. As such the components, examples, and performance tuning are geared towards operation as a WebSocket client or server. There are some minimal convenience features that stray from this (for example the ability to respond to HTTP requests other than WebSocket Upgrades) but these are not the focus of the project. In particular WebSocket++ does not intend to implement any non-WebSocket related fallback options (ajax / long polling / comet / etc).
In order to remain compact and improve portability, the WebSocket++ project strives to reduce or eliminate external dependencies where possible and appropriate. WebSocket++ core has no dependencies other than the C++11 standard library. For non-C++11 compilers the Boost libraries provide drop in polyfills for the C++11 functionality used.
WebSocket++ implements a pluggable data transport component. The default component allows reduced functionality by using STL iostream or raw byte shuffling via reading and writing char buffers. This component has no non-STL dependencies and can be used in a C++11 environment without Boost. Also included is an Asio based transport component that provides full featured network client/server functionality. This component requires either Boost Asio or a C++11 compiler and standalone Asio. As an advanced option, WebSocket++ supports custom transport layers if you want to provide your own using another library.
In order to accommodate the wide variety of use cases WebSocket++ has collected, the library is built in a way that most of the major components are loosely coupled and can be swapped out and replaced. WebSocket++ will attempt to track the future development of the WebSocket protocol and any extensions as they are developed.

Frequently asked questions
--------------------------
Q: How much data can Flot cope with?
A: Flot will happily draw everything you send to it so the answer
depends on the browser. The excanvas emulation used for IE (built with
VML) makes IE by far the slowest browser so be sure to test with that
if IE users are in your target group.
1000 points is not a problem, but as soon as you start having more
points than the pixel width, you should probably start thinking about
downsampling/aggregation as this is near the resolution limit of the
chart anyway. If you downsample server-side, you also save bandwidth.
Q: Flot isn't working when I'm using JSON data as source!
A: Actually, Flot loves JSON data, you just got the format wrong.
Double check that you're not inputting strings instead of numbers,
like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and
the error might not show up immediately because Javascript can do some
conversion automatically.
Q: Can I export the graph?
A: This is a limitation of the canvas technology. There's a hook in
the canvas object for getting an image out, but you won't get the tick
labels. And it's not likely to be supported by IE. At this point, your
best bet is probably taking a screenshot, e.g. with PrtScn.
Q: The bars are all tiny in time mode?
A: It's not really possible to determine the bar width automatically.
So you have to set the width with the barWidth option which is NOT in
pixels, but in the units of the x axis (or the y axis for horizontal
bars). For time mode that's milliseconds so the default value of 1
makes the bars 1 millisecond wide.
Q: Can I use Flot with libraries like Mootools or Prototype?
A: Yes, Flot supports it out of the box and it's easy! Just use jQuery
instead of $, e.g. call jQuery.plot instead of $.plot and use
jQuery(something) instead of $(something). As a convenience, you can
put in a DOM element for the graph placeholder where the examples and
the API documentation are using jQuery objects.
Depending on how you include jQuery, you may have to add one line of
code to prevent jQuery from overwriting functions from the other
libraries, see the documentation in jQuery ("Using jQuery with other
libraries") for details.
Q: Flot doesn't work with [insert name of Javascript UI framework]!
A: The only non-standard thing used by Flot is the canvas tag;
otherwise it is simply a series of absolute positioned divs within the
placeholder tag you put in. If this is not working, it's probably
because the framework you're using is doing something weird with the
DOM, or you're using it the wrong way.
A common problem is that there's display:none on a container until the
user does something. Many tab widgets work this way, and there's
nothing wrong with it - you just can't call Flot inside a display:none
container as explained in the README so you need to hold off the Flot
call until the container is actually displayed (or use
visibility:hidden instead of display:none or move the container
off-screen).
If you find there's a specific thing we can do to Flot to help, feel
free to submit a bug report. Otherwise, you're welcome to ask for help
on the forum/mailing list, but please don't submit a bug report to
Flot.

Flot 0.7
--------
API changes:
Multiple axes support. Code using dual axes should be changed from
using x2axis/y2axis in the options to using an array (although
backwards-compatibility hooks are in place). For instance,
{
xaxis: { ... }, x2axis: { ... },
yaxis: { ... }, y2axis: { ... }
}
becomes
{
xaxes: [ { ... }, { ... } ],
yaxes: [ { ... }, { ... } ]
}
Note that if you're just using one axis, continue to use the
xaxis/yaxis directly (it now sets the default settings for the
arrays). Plugins touching the axes must be ported to take the extra
axes into account, check the source to see some examples.
A related change is that the visibility of axes is now auto-detected.
So if you were relying on an axis to show up even without any data in
the chart, you now need to set the axis "show" option explicitly.
"tickColor" on the grid options is now deprecated in favour of a
corresponding option on the axes, so { grid: { tickColor: "#000" }}
becomes { xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} },
but if you just configure a base color Flot will now autogenerate a
tick color by adding transparency. Backwards-compatibility hooks are
in place.
Final note: now that IE 9 is coming out with canvas support, you may
want to adapt the excanvas include to skip loading it in IE 9 (the
examples have been adapted thanks to Ryley Breiddal). An alternative
to excanvas using Flash has also surfaced, if your graphs are slow in
IE, you may want to give it a spin:
http://code.google.com/p/flashcanvas/
Changes:
- Support for specifying a bottom for each point for line charts when
filling them, this means that an arbitrary bottom can be used
instead of just the x axis (based on patches patiently provided by
Roman V. Prikhodchenko).
- New fillbetween plugin that can compute a bottom for a series from
another series, useful for filling areas between lines (see new
example percentiles.html for a use case).
- More predictable handling of gaps for the stacking plugin, now all
undefined ranges are skipped.
- Stacking plugin can stack horizontal bar charts.
- Navigate plugin now redraws the plot while panning instead of only
after the fact (can be disabled by setting the pan.frameRate option
to null), raised by lastthemy (issue 235).
- Date formatter now accepts %0m and %0d to get a zero-padded month or
day (issue raised by Maximillian Dornseif).
- Revamped internals to support an unlimited number of axes, not just
dual (sponsored by Flight Data Services,
www.flightdataservices.com).
- New setting on axes, "tickLength", to control the size of ticks or
turn them off without turning off the labels.
- Axis labels are now put in container divs with classes, for instance
labels in the x axes can be reached via ".xAxis .tickLabel".
- Support for setting the color of an axis (sponsored by Flight Data
Services, www.flightdataservices.com).
- Tick color is now auto-generated as the base color with some
transparency (unless you override it).
- Support for aligning ticks in the axes with "alignTicksWithAxis" to
ensure that they appear next to each other rather than in between,
at the expense of possibly awkward tick steps (sponsored by Flight
Data Services, www.flightdataservices.com).
- Support for customizing the point type through a callback when
plotting points and new symbol plugin with some predefined point
types (sponsored by Utility Data Corporation).
- Resize plugin for automatically redrawing when the placeholder
changes size, e.g. on window resizes (sponsored by Novus Partners).
A resize() method has been added to plot object facilitate this.
- Support Infinity/-Infinity for plotting asymptotes by hacking it
into +/-Number.MAX_VALUE (reported by rabaea.mircea).
- Support for restricting navigate plugin to not pan/zoom an axis (based
on patch by kkaefer).
- Support for providing the drag cursor for the navigate plugin as an
option (based on patch by Kelly T. Moore).
- Options for controlling whether an axis is shown or not (suggestion
by Timo Tuominen) and whether to reserve space for it even if it
isn't shown.
- New attribute $.plot.version with the Flot version as a string.
- The version comment is now included in the minified jquery.flot.min.js.
- New options.grid.minBorderMargin for adjusting the minimum margin
provided around the border (based on patch by corani, issue 188).
- Refactor replot behaviour so Flot tries to reuse the existing
canvas, adding shutdown() methods to the plot (based on patch by
Ryley Breiddal, issue 269). This prevents a memory leak in Chrome
and hopefully makes replotting faster for those who are using $.plot
instead of .setData()/.draw(). Also update jQuery to 1.5.1 to
prevent IE leaks fixed in jQuery.
- New real-time line chart example.
- New hooks: drawSeries, shutdown
Bug fixes:
- Fixed problem with findNearbyItem and bars on top of each other
(reported by ragingchikn, issue 242).
- Fixed problem with ticks and the border (based on patch from
ultimatehustler69, issue 236).
- Fixed problem with plugins adding options to the series objects.
- Fixed a problem introduced in 0.6 with specifying a gradient with {
brightness: x, opacity: y }.
- Don't use $.browser.msie, check for getContext on the created canvas
element instead and try to use excanvas if it's not found (fixes IE
9 compatibility).
- highlight(s, index) was looking up the point in the original s.data
instead of in the computed datapoints array, which breaks with
plugins that modify the datapoints (such as the stacking plugin).
Issue 316 reported by curlypaul924.
- More robust handling of axis from data passed in from getData()
(problem reported by Morgan).
- Fixed problem with turning off bar outline (issue 253, fix by Jordi
Castells).
- Check the selection passed into setSelection in the selection
plugin, to guard against errors when synchronizing plots (fix by Lau
Bech Lauritzen).
- Fix bug in crosshair code with mouseout resetting the crosshair even
if it is locked (fix by Lau Bech Lauritzen and Banko Adam).
- Fix bug with points plotting using line width from lines rather than
points.
- Fix bug with passing non-array 0 data (for plugins that don't expect
arrays, patch by vpapp1).
- Fix errors in JSON in examples so they work with jQuery 1.4.2
(fix reported by honestbleeps, issue 357).
- Fix bug with tooltip in interacting.html, this makes the tooltip
much smoother (fix by bdkahn). Fix related bug inside highlighting
handler in Flot.
- Use closure trick to make inline colorhelpers plugin respect
jQuery.noConflict(true), renaming the global jQuery object (reported
by Nick Stielau).
- Listen for mouseleave events and fire a plothover event with empty
item when it occurs to drop highlights when the mouse leaves the
plot (reported by by outspirit).
- Fix bug with using aboveData with a background (reported by
amitayd).
- Fix possible excanvas leak (report and suggested fix by tom9729).
- Fix bug with backwards compatibility for shadowSize = 0 (report and
suggested fix by aspinak).
- Adapt examples to skip loading excanvas (fix by Ryley Breiddal).
- Fix bug that prevent a simple f(x) = -x transform from working
correctly (fix by Mike, issue 263).
- Fix bug in restoring cursor in navigate plugin (reported by Matteo
Gattanini, issue 395).
- Fix bug in picking items when transform/inverseTransform is in use
(reported by Ofri Raviv, and patches and analysis by Jan and Tom
Paton, issue 334 and 467).
- Fix problem with unaligned ticks and hover/click events caused by
padding on the placeholder by hardcoding the placeholder padding to
0 (reported by adityadineshsaxena, Matt Sommer, Daniel Atos and some
other people, issue 301).
- Update colorhelpers plugin to avoid dying when trying to parse an
invalid string (reported by cadavor, issue 483).
Flot 0.6
--------
API changes:
1. Selection support has been moved to a plugin. Thus if you're
passing selection: { mode: something }, you MUST include the file
jquery.flot.selection.js after jquery.flot.js. This reduces the size
of base Flot and makes it easier to customize the selection as well as
improving code clarity. The change is based on a patch from andershol.
2. In the global options specified in the $.plot command,
"lines", "points", "bars" and "shadowSize" have been moved to a
sub-object called "series", i.e.
$.plot(placeholder, data, { lines: { show: true }})
should be changed to
$.plot(placeholder, data, { series: { lines: { show: true }}})
All future series-specific options will go into this sub-object to
simplify plugin writing. Backward-compatibility code is in place, so
old code should not break.
3. "plothover" no longer provides the original data point, but instead
a normalized one, since there may be no corresponding original point.
4. Due to a bug in previous versions of jQuery, you now need at least
jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some
improvements in event handling speed.
Changes:
- Added support for disabling interactivity for specific data series
(request from Ronald Schouten and Steve Upton).
- Flot now calls $() on the placeholder and optional legend container
passed in so you can specify DOM elements or CSS expressions to make
it easier to use Flot with libraries like Prototype or Mootools or
through raw JSON from Ajax responses.
- A new "plotselecting" event is now emitted while the user is making
a selection.
- The "plothover" event is now emitted immediately instead of at most
10 times per second, you'll have to put in a setTimeout yourself if
you're doing something really expensive on this event.
- The built-in date formatter can now be accessed as
$.plot.formatDate(...) (suggestion by Matt Manela) and even
replaced.
- Added "borderColor" option to the grid (patch from Amaury Chamayou
and patch from Mike R. Williamson).
- Added support for gradient backgrounds for the grid, take a look at
the "setting options" example (based on patch from Amaury Chamayou,
issue 90).
- Gradient bars (suggestion by stefpet).
- Added a "plotunselected" event which is triggered when the selection
is removed, see "selection" example (suggestion by Meda Ugo);
- The option legend.margin can now specify horizontal and vertical
margins independently (suggestion by someone who's annoyed).
- Data passed into Flot is now copied to a new canonical format to
enable further processing before it hits the drawing routines. As a
side-effect, this should make Flot more robust in the face of bad
data (and fixes issue 112).
- Step-wise charting: line charts have a new option "steps" that when
set to true connects the points with horizontal/vertical steps
instead of diagonal lines.
- The legend labelFormatter now passes the series in addition to just
the label (suggestion by Vincent Lemeltier).
- Horizontal bars (based on patch by Jason LeBrun).
- Support for partial bars by specifying a third coordinate, i.e. they
don't have to start from the axis. This can be used to make stacked
bars.
- New option to disable the (grid.show).
- Added pointOffset method for converting a point in data space to an
offset within the placeholder.
- Plugin system: register an init method in the $.flot.plugins array
to get started, see PLUGINS.txt for details on how to write plugins
(it's easy). There are also some extra methods to enable access to
internal state.
- Hooks: you can register functions that are called while Flot is
crunching the data and doing the plot. This can be used to modify
Flot without changing the source, useful for writing plugins. Some
hooks are defined, more are likely to come.
- Threshold plugin: you can set a threshold and a color, and the data
points below that threshold will then get the color. Useful for
marking data below 0, for instance.
- Stack plugin: you can specify a stack key for each series to have
them summed. This is useful for drawing additive/cumulative graphs
with bars and (currently unfilled) lines.
- Crosshairs plugin: trace the mouse position on the axes, enable with
crosshair: { mode: "x"} (see the new tracking example for a use).
- Image plugin: plot prerendered images.
- Navigation plugin for panning and zooming a plot.
- More configurable grid.
- Axis transformation support, useful for non-linear plots, e.g. log
axes and compressed time axes (like omitting weekends).
- Support for twelve-hour date formatting (patch by Forrest Aldridge).
- The color parsing code in Flot has been cleaned up and split out so
it's now available as a separate jQuery plugin. It's included inline
in the Flot source to make dependency managing easier. This also
makes it really easy to use the color helpers in Flot plugins.
Bug fixes:
- Fixed two corner-case bugs when drawing filled curves (report and
analysis by Joshua Varner).
- Fix auto-adjustment code when setting min to 0 for an axis where the
dataset is completely flat on that axis (report by chovy).
- Fixed a bug with passing in data from getData to setData when the
secondary axes are used (issue 65, reported by nperelman).
- Fixed so that it is possible to turn lines off when no other chart
type is shown (based on problem reported by Glenn Vanderburg), and
fixed so that setting lineWidth to 0 also hides the shadow (based on
problem reported by Sergio Nunes).
- Updated mousemove position expression to the latest from jQuery (bug
reported by meyuchas).
- Use CSS borders instead of background in legend (fix printing issue 25
and 45).
- Explicitly convert axis min/max to numbers.
- Fixed a bug with drawing marking lines with different colors
(reported by Khurram).
- Fixed a bug with returning y2 values in the selection event (fix
by exists, issue 75).
- Only set position relative on placeholder if it hasn't already a
position different from static (reported by kyberneticist, issue 95).
- Don't round markings to prevent sub-pixel problems (reported by Dan
Lipsitt).
- Make the grid border act similarly to a regular CSS border, i.e.
prevent it from overlapping the plot itself. This also fixes a
problem with anti-aliasing when the width is 1 pixel (reported by
Anthony Ettinger).
- Imported version 3 of excanvas and fixed two issues with the newer
version. Hopefully, this will make Flot work with IE8 (nudge by
Fabien Menager, further analysis by Booink, issue 133).
- Changed the shadow code for lines to hopefully look a bit better
with vertical lines.
- Round tick positions to avoid possible problems with fractions
(suggestion by Fred, issue 130).
- Made the heuristic for determining how many ticks to aim for a bit
smarter.
- Fix for uneven axis margins (report and patch by Paul Kienzle) and
snapping to ticks (concurrent report and patch by lifthrasiir).
- Fixed bug with slicing in findNearbyItems (patch by zollman).
- Make heuristic for x axis label widths more dynamic (patch by
rickinhethuis).
- Make sure points on top take precedence when finding nearby points
when hovering (reported by didroe, issue 224).
Flot 0.5
--------
Backwards API change summary: Timestamps are now in UTC. Also
"selected" event -> becomes "plotselected" with new data, the
parameters for setSelection are now different (but backwards
compatibility hooks are in place), coloredAreas becomes markings with
a new interface (but backwards compatibility hooks are in place).
Interactivity: added a new "plothover" event and this and the
"plotclick" event now returns the closest data item (based on patch by
/david, patch by Mark Byers for bar support). See the revamped
"interacting with the data" example for some hints on what you can do.
Highlighting: you can now highlight points and datapoints are
autohighlighted when you hover over them (if hovering is turned on).
Support for dual axis has been added (based on patch by someone who's
annoyed and /david). For each data series you can specify which axes
it belongs to, and there are two more axes, x2axis and y2axis, to
customize. This affects the "selected" event which has been renamed to
"plotselected" and spews out { xaxis: { from: -10, to: 20 } ... },
setSelection in which the parameters are on a new form (backwards
compatible hooks are in place so old code shouldn't break) and
markings (formerly coloredAreas).
Timestamps in time mode are now displayed according to
UTC instead of the time zone of the visitor. This affects the way the
timestamps should be input; you'll probably have to offset the
timestamps according to your local time zone. It also affects any
custom date handling code (which basically now should use the
equivalent UTC date mehods, e.g. .setUTCMonth() instead of
.setMonth().
Added support for specifying the size of tick labels (axis.labelWidth,
axis.labelHeight). Useful for specifying a max label size to keep
multiple plots aligned.
Markings, previously coloredAreas, are now specified as ranges on the
axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings
you can now draw horizontal/vertical lines by setting from and to to
the same coordinate (idea from line support patch by by Ryan Funduk).
The "fill" option can now be a number that specifies the opacity of
the fill.
You can now specify a coordinate as null (like [2, null]) and Flot
will take the other coordinate into account when scaling the axes
(based on patch by joebno).
New option for bars "align". Set it to "center" to center the bars on
the value they represent.
setSelection now takes a second parameter which you can use to prevent
the method from firing the "plotselected" handler.
Using the "container" option in legend now overwrites the container
element instead of just appending to it (fixes infinite legend bug,
reported by several people, fix by Brad Dewey).
Fixed a bug in calculating spacing around the plot (reported by
timothytoe). Fixed a bug in finding max values for all-negative data
sets. Prevent the possibility of eternal looping in tick calculations.
Fixed a bug when borderWidth is set to 0 (reported by
Rob/sanchothefat). Fixed a bug with drawing bars extending below 0
(reported by James Hewitt, patch by Ryan Funduk). Fixed a
bug with line widths of bars (reported by MikeM). Fixed a bug with
'nw' and 'sw' legend positions. Improved the handling of axis
auto-scaling with bars. Fixed a bug with multi-line x-axis tick
labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
Flot 0.4
--------
API changes: deprecated axis.noTicks in favor of just specifying the
number as axis.ticks. So "xaxis: { noTicks: 10 }" becomes
"xaxis: { ticks: 10 }"
Time series support. Specify axis.mode: "time", put in Javascript
timestamps as data, and Flot will automatically spit out sensible
ticks. Take a look at the two new examples. The format can be
customized with axis.timeformat and axis.monthNames, or if that fails
with axis.tickFormatter.
Support for colored background areas via grid.coloredAreas. Specify an
array of { x1, y1, x2, y2 } objects or a function that returns these
given { xmin, xmax, ymin, ymax }.
More members on the plot object (report by Chris Davies and others).
"getData" for inspecting the assigned settings on data series (e.g.
color) and "setData", "setupGrid" and "draw" for updating the contents
without a total replot.
The default number of ticks to aim for is now dependent on the size of
the plot in pixels. Support for customizing tick interval sizes
directly with axis.minTickSize and axis.tickSize.
Cleaned up the automatic axis scaling algorithm and fixed how it
interacts with ticks. Also fixed a couple of tick-related corner case
bugs (one reported by mainstreetmark, another reported by timothytoe).
The option axis.tickFormatter now takes a function with two
parameters, the second parameter is an optional object with
information about the axis. It has min, max, tickDecimals, tickSize.
Added support for segmented lines (based on patch from Michael
MacDonald) and for ignoring null and bad values (suggestion from Nick
Konidaris and joshwaihi).
Added support for changing the border width (joebno and safoo).
Label colors can be changed via CSS by selecting the tickLabel class.
Fixed a bug in handling single-item bar series (reported by Emil
Filipov). Fixed erratic behaviour when interacting with the plot
with IE 7 (reported by Lau Bech Lauritzen). Prevent IE/Safari text
selection when selecting stuff on the canvas.
Flot 0.3
--------
This is mostly a quick-fix release because jquery.js wasn't included
in the previous zip/tarball.
Support clicking on the plot. Turn it on with grid: { clickable: true },
then you get a "plotclick" event on the graph placeholder with the
position in units of the plot.
Fixed a bug in dealing with data where min = max, thanks to Michael
Messinides.
Include jquery.js in the zip/tarball.
Flot 0.2
--------
Added support for putting a background behind the default legend. The
default is the partly transparent background color. Added
backgroundColor and backgroundOpacity to the legend options to control
this.
The ticks options can now be a callback function that takes one
parameter, an object with the attributes min and max. The function
should return a ticks array.
Added labelFormatter option in legend, useful for turning the legend
labels into links.
Fixed a couple of bugs.
The API should now be fully documented.
Patch from Guy Fraser to make parts of the code smaller.
API changes: Moved labelMargin option to grid from x/yaxis.
Flot 0.1
--------
First public release.

Writing plugins
---------------
All you need to do to make a new plugin is creating an init function
and a set of options (if needed), stuffing it into an object and
putting it in the $.plot.plugins array. For example:
function myCoolPluginInit(plot) {
plot.coolstring = "Hello!";
};
$.plot.plugins.push({ init: myCoolPluginInit, options: { ... } });
// if $.plot is called, it will return a plot object with the
// attribute "coolstring"
Now, given that the plugin might run in many different places, it's
a good idea to avoid leaking names. The usual trick here is wrap the
above lines in an anonymous function which is called immediately, like
this: (function () { inner code ... })(). To make it even more robust
in case $ is not bound to jQuery but some other Javascript library, we
can write it as
(function ($) {
// plugin definition
// ...
})(jQuery);
There's a complete example below, but you should also check out the
plugins bundled with Flot.
Complete example
----------------
Here is a simple debug plugin which alerts each of the series in the
plot. It has a single option that control whether it is enabled and
how much info to output:
(function ($) {
function init(plot) {
var debugLevel = 1;
function checkDebugEnabled(plot, options) {
if (options.debug) {
debugLevel = options.debug;
plot.hooks.processDatapoints.push(alertSeries);
}
}
function alertSeries(plot, series, datapoints) {
var msg = "series " + series.label;
if (debugLevel > 1)
msg += " with " + series.data.length + " points";
alert(msg);
}
plot.hooks.processOptions.push(checkDebugEnabled);
}
var options = { debug: 0 };
$.plot.plugins.push({
init: init,
options: options,
name: "simpledebug",
version: "0.1"
});
})(jQuery);
We also define "name" and "version". It's not used by Flot, but might
be helpful for other plugins in resolving dependencies.
Put the above in a file named "jquery.flot.debug.js", include it in an
HTML page and then it can be used with:
$.plot($("#placeholder"), [...], { debug: 2 });
This simple plugin illustrates a couple of points:
- It uses the anonymous function trick to avoid name pollution.
- It can be enabled/disabled through an option.
- Variables in the init function can be used to store plot-specific
state between the hooks.
The two last points are important because there may be multiple plots
on the same page, and you'd want to make sure they are not mixed up.
Shutting down a plugin
----------------------
Each plot object has a shutdown hook which is run when plot.shutdown()
is called. This usually mostly happens in case another plot is made on
top of an existing one.
The purpose of the hook is to give you a chance to unbind any event
handlers you've registered and remove any extra DOM things you've
inserted.
The problem with event handlers is that you can have registered a
handler which is run in some point in the future, e.g. with
setTimeout(). Meanwhile, the plot may have been shutdown and removed,
but because your event handler is still referencing it, it can't be
garbage collected yet, and worse, if your handler eventually runs, it
may overwrite stuff on a completely different plot.
Some hints on the options
-------------------------
Plugins should always support appropriate options to enable/disable
them because the plugin user may have several plots on the same page
where only one should use the plugin. In most cases it's probably a
good idea if the plugin is turned off rather than on per default, just
like most of the powerful features in Flot.
If the plugin needs options that are specific to each series, like the
points or lines options in core Flot, you can put them in "series" in
the options object, e.g.
var options = {
series: {
downsample: {
algorithm: null,
maxpoints: 1000
}
}
}
Then they will be copied by Flot into each series, providing default
values in case none are specified.
Think hard and long about naming the options. These names are going to
be public API, and code is going to depend on them if the plugin is
successful.

About
-----
Flot is a Javascript plotting library for jQuery. Read more at the
website:
http://code.google.com/p/flot/
Take a look at the examples linked from above, they should give a good
impression of what Flot can do and the source code of the examples is
probably the fastest way to learn how to use Flot.
Installation
------------
Just include the Javascript file after you've included jQuery.
Generally, all browsers that support the HTML5 canvas tag are
supported.
For support for Internet Explorer < 9, you can use Excanvas, a canvas
emulator; this is used in the examples bundled with Flot. You just
include the excanvas script like this:
<!--[if lte IE 8]><script language="javascript" type="text/javascript" src="excanvas.min.js"></script><![endif]-->
If it's not working on your development IE 6.0, check that it has
support for VML which Excanvas is relying on. It appears that some
stripped down versions used for test environments on virtual machines
lack the VML support.
You can also try using Flashcanvas (see
http://code.google.com/p/flashcanvas/), which uses Flash to do the
emulation. Although Flash can be a bit slower to load than VML, if
you've got a lot of points, the Flash version can be much faster
overall. Flot contains some wrapper code for activating Excanvas which
Flashcanvas is compatible with.
You need at least jQuery 1.2.6, but try at least 1.3.2 for interactive
charts because of performance improvements in event handling.
Basic usage
-----------
Create a placeholder div to put the graph in:
<div id="placeholder"></div>
You need to set the width and height of this div, otherwise the plot
library doesn't know how to scale the graph. You can do it inline like
this:
<div id="placeholder" style="width:600px;height:300px"></div>
You can also do it with an external stylesheet. Make sure that the
placeholder isn't within something with a display:none CSS property -
in that case, Flot has trouble measuring label dimensions which
results in garbled looks and might have trouble measuring the
placeholder dimensions which is fatal (it'll throw an exception).
Then when the div is ready in the DOM, which is usually on document
ready, run the plot function:
$.plot($("#placeholder"), data, options);
Here, data is an array of data series and options is an object with
settings if you want to customize the plot. Take a look at the
examples for some ideas of what to put in or look at the reference
in the file "API.txt". Here's a quick example that'll draw a line from
(0, 0) to (1, 1):
$.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } });
The plot function immediately draws the chart and then returns a plot
object with a couple of methods.
What's with the name?
---------------------
First: it's pronounced with a short o, like "plot". Not like "flawed".
So "Flot" rhymes with "plot".
And if you look up "flot" in a Danish-to-English dictionary, some up
the words that come up are "good-looking", "attractive", "stylish",
"smart", "impressive", "extravagant". One of the main goals with Flot
is pretty looks.

<p>Example of loading data dynamically with AJAX. Percentage change in GDP (source: <a href="http://epp.eurostat.ec.europa.eu/tgm/table.do?tab=table&init=1&plugin=1&language=en&pcode=tsieb020">Eurostat</a>). Click the buttons below.</p>
<p>The data is fetched over HTTP, in this case directly from text
files. Usually the URL would point to some web server handler
(e.g. a PHP page or Java/.NET/Python/Ruby on Rails handler) that
extracts it from a database and serializes it to JSON.</p>
<p>
<input class="fetchSeries" type="button" value="First dataset"> -

also direct access to the canvas.</p>

<p>With the image plugin, you can plot images. This is for example
useful for getting ticks on complex prerendered visualizations.
Instead of inputting data points, you put in the images and where
their two opposite corners are supposed to be in plot space.</p>
<p>Images represent a little further complication because you need
to make sure they are loaded before you can use them (Flot skips
incomplete images). The plugin comes with a couple of helpers
for doing that.</p>

<p>With the navigate plugin it is easy to add panning and zooming.
Drag to pan, double click to zoom (or use the mouse scrollwheel).</p>
<p>The plugin fires events (useful for synchronizing several
plots) and adds a couple of public methods so you can easily build
a little user interface around it, like the little buttons at the
top right in the plot.</p>

<p>Height in centimeters of individuals from the US (2003-2006) as function of
age in years (source: <a href="http://www.cdc.gov/nchs/data/nhsr/nhsr010.pdf">CDC</a>).
The 15%-85%, 25%-75% and 50% percentiles are indicated.</p>
<p>For each point of a filled curve, you can specify an arbitrary
bottom. As this example illustrates, this can be useful for
plotting percentiles. If you have the data sets available without
appropriate fill bottoms, you can use the fillbetween plugin to
compute the data point bottoms automatically.</p>

<h2>Pie Options</h2>
<ul class="options">
<li style="border-bottom: 1px dotted #ccc;"><b>option:</b> <i>default value</i> - Description of option</li>
<li><b>show:</b> <i>false</i> - Enable the plugin and draw as a pie.</li>
<li><b>radius:</b> <i>'auto'</i> - Sets the radius of the pie. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length. If set to 'auto', it will be set to 1 if the legend is enabled and 3/4 if not.</li>
<li><b>innerRadius:</b> <i>0</i> - Sets the radius of the donut hole. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the radius, otherwise it will use the value as a direct pixel length.</li>
<li><b>startAngle:</b> <i>3/2</i> - Factor of PI used for the starting angle (in radians) It can range between 0 and 2 (where 0 and 2 have the same result).</li>
<li><b>tilt:</b> <i>1</i> - Percentage of tilt ranging from 0 and 1, where 1 has no change (fully vertical) and 0 is completely flat (fully horizontal -- in which case nothing actually gets drawn).</li>
<li><b>offset:</b> <ul>
<li><b>top:</b> <i>0</i> - Pixel distance to move the pie up and down (relative to the center).</li>
<li><b>left:</b> <i>'auto'</i> - Pixel distance to move the pie left and right (relative to the center).</li>
</ul>
<li><b>stroke:</b> <ul>
<li><b>color:</b> <i>'#FFF'</i> - Color of the border of each slice. Hexadecimal color definitions are prefered (other formats may or may not work).</li>
<li><b>width:</b> <i>1</i> - Pixel width of the border of each slice.</li>
</ul>
<li><b>label:</b> <ul>
<li><b>show:</b> <i>'auto'</i> - Enable/Disable the labels. This can be set to true, false, or 'auto'. When set to 'auto', it will be set to false if the legend is enabled and true if not.</li>
<li><b>radius:</b> <i>1</i> - Sets the radius at which to place the labels. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length.</li>
<li><b>threshold:</b> <i>0</i> - Hides the labels of any pie slice that is smaller than the specified percentage (ranging from 0 to 1) i.e. a value of '0.03' will hide all slices 3% or less of the total.</li>
<li><b>formatter:</b> <i>[function]</i> - This function specifies how the positioned labels should be formatted, and is applied after the legend's labelFormatter function. The labels can also still be styled using the class "pieLabel" (i.e. ".pieLabel" or "#graph1 .pieLabel").</li>
<li><b>radius:</b> <i>1</i> - Sets the radius at which to place the labels. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length.</li>
<li><b>background:</b> <ul>
<li><b>color:</b> <i>null</i> - Backgound color of the positioned labels. If null, the plugin will automatically use the color of the slice.</li>
<li><b>opacity:</b> <i>0</i> - Opacity of the background for the positioned labels. Acceptable values range from 0 to 1, where 0 is completely transparent and 1 is completely opaque.</li>
</ul>
</ul>
<li><b>combine:</b> <ul>
<li><b>threshold:</b> <i>0</i> - Combines all slices that are smaller than the specified percentage (ranging from 0 to 1) i.e. a value of '0.03' will combine all slices 3% or less into one slice).</li>
<li><b>color:</b> <i>null</i> - Backgound color of the positioned labels. If null, the plugin will automatically use the color of the first slice to be combined.</li>
<li><b>label:</b> <i>'Other'</i> - Label text for the combined slice.</li>
</ul>
<li><b>highlight:</b> <ul>
<li><b>opacity:</b> <i>0.5</i> - Opacity of the highlight overlay on top of the current pie slice. Currently this just uses a white overlay, but support for changing the color of the overlay will also be added at a later date.
</ul>
</ul>
<h2>Changes/Features</h2>
<ul>
<li style="list-style: none;"><i>v1.0 - November 20th, 2009 - Brian Medendorp</i></li>
<li>The pie plug-in is now part of the Flot repository! This should make it a lot easier to deal with.</li>
<li>Added a new option (innerRadius) to add a "donut hole" to the center of the pie, based on comtributions from Anthony Aragues. I was a little reluctant to add this feature because it doesn't work very well with the shadow created for the tilted pie, but figured it was worthwhile for non-tilted pies. Also, excanvas apparently doesn't support compositing, so it will fall back to using the stroke color to fill in the center (but I recommend setting the stroke color to the background color anyway).</li>
<li>Changed the lineJoin for the border of the pie slices to use the 'round' option. This should make the center of the pie look better, particularly when there are numerous thin slices.</li>
<li>Included a bug fix submitted by btburnett3 to display a slightly smaller slice in the event that the slice is 100% and being rendered with Internet Explorer. I haven't experienced this bug myself, but it doesn't seem to hurt anything so I've included it.</li>
<li>The tilt value is now used when calculating the maximum radius of the pie in relation to the height of the container. This should prevent the pie from being smaller than it needed to in some cases, as well as reducing the amount of extra white space generated above and below the pie.</li>
<li><b>Hover and Click functionality are now availabe!</b><ul>
<li>Thanks to btburnett3 for the original hover functionality and Anthony Aragues for the modification that makes it compatable with excanvas, this was a huge help!</li>
<li>Added a new option (highlight opacity) to modify the highlight created when mousing over a slice. Currently this just uses a white overlay, but an option to change the hightlight color will be added when the appropriate functionality becomes available.
<li>I had a major setback that required me to practically rebuild the hover/click events from scratch one piece at a time (I discovered that it only worked with a single pie on a page at a time), but the end result ended up being virtually identical to the original, so I'm not quite sure what exactly made it work.</li>
<li><span style="color: red;">Warning:</span> There are some minor issues with using this functionality in conjuction with some of the other more advanced features (tilt and donut). When using a donut hole, the inner portion still triggers the events even though that portion of the pie is no longer visible. When tilted, the interactive portions still use the original, untilted version of the pie when determining mouse position (this is because the isPointInPath function apparently doesn't work with transformations), however hover and click both work this way, so the appropriate slice is still highlighted when clicking, and it isn't as noticable of a problem.</li>
</ul></li>
<li>Included a bug fix submitted by Xavi Ivars to fix array issues when other javascript libraries are included in addition to jQuery</li>
<br/>
<li style="list-style: none;"><i>v0.4 - July 1st, 2009 - Brian Medendorp</i></li>
<li>Each series will now be shown in the legend, even if it's value is zero. The series will not get a positioned label because it will overlap with the other labels present and often makes them unreadable.</li>
<li>Data can now be passed in using the standard Flot method using an array of datapoints, the pie plugin will simply use the first y-value that it finds for each series in this case. The plugin uses this datastructure internally, but you can still use the old method of passing in a single numerical value for each series (the plugin will convert it as necessary). This should make it easier to transition from other types of graphs (such as a stacked bar graph) to a pie.</li>
<li>The pie can now be tilted at an angle with a new "tilt" option. Acceptable values range from 0-1, where 1 has no change (fully vertical) and 0 is completely flat (fully horizontal -- in which case nothing actually gets drawn). If the plugin determines that it will fit within the canvas, a drop shadow will be drawn under the tilted pie (this also requires a tilt value of 0.8 or less).</li>
<br/>
<li style="list-style: none;"><i>v0.3.2 - June 25th, 2009 - Brian Medendorp</i></li>
<li>Fixed a bug that was causing the pie to be shifted too far left or right when the legend is showing in some cases.</li>
<br/>
<li style="list-style: none;"><i>v0.3.1 - June 24th, 2009 - Brian Medendorp</i></li>
<li>Fixed a bug that was causing nothing to be drawn and generating a javascript error if any of the data values were set to zero.</li>
<br/>
<li style="list-style: none;"><i>v0.3 - June 23rd, 2009 - Brian Medendorp</i></li>
<li>The legend now works without any modifications! Because of changes made to flot and the plugin system (thanks Ole Laursen!) I was able to simplify a number of things and am now able to use the legend without the direct access hack that was required in the previous version.</li>
<br/>
<li style="list-style: none;"><i>v0.2 - June 22nd, 2009 - Brian Medendorp</i></li>
<li>The legend now works but only if you make the necessary changes to jquery.flot.js. Because of this, I changed the default values for pie.radius and pie.label.show to new 'auto' settings that change the default behavior of the size and labels depending on whether the legend functionality is available or not.</li>
<br/>
<li style="list-style: none;"><i>v0.1 - June 18th, 2009 - Brian Medendorp</i></li>
<li>Rewrote the entire pie code into a flot plugin (since that is now an option), so it should be much easier to use and the code is cleaned up a bit. However, the (standard flot) legend is no longer available because the only way to prevent the grid lines from being displayed also prevents the legend from being displayed. Hopefully this can be fixed at a later date.</li>
<li>Restructured and combined some of the options. It should be much easier to deal with now.</li>
<li>Added the ability to change the starting point of the pie (still defaults to the top).</li>
<li>Modified the default options to show the labels to compensate for the lack of a legend.</li>
<li>Modified this page to use a random dataset. <span style="color: red">Note: you may need to refresh the page to see the effects of some of the examples.</span></li>
<br/>
<li style="list-style: none;"><i>May 21st, 2009 - Brian Medendorp</i></li>
<li>Merged original pie modifications by Sergey Nosenko into the latest SVN version <i>(as of May 15th, 2009)</i> so that it will work with ie8.</li>
<li>Pie graph will now be centered in the canvas unless moved because of the legend or manually via the options. Additionally it prevents the pie from being moved beyond the edge of the canvas.</li>
<li>Modified the code related to the labelFormatter option to apply flot's legend labelFormatter first. This is so that the labels will be consistent, but still provide extra formatting for the positioned labels (such as adding the percentage value).</li>
<li>Positioned labels now have their backgrounds applied as a seperate element (much like the legend background) so that the opacity value can be set independently from the label itself (foreground). Additionally, the background color defaults to that of the matching slice.</li>
<li>As long as the labelOffset and radiusLimit are not set to hard values, the pie will be shrunk if the labels will extend outside the edge of the canvas</li>
<li>Added new options "radiusLimitFactor" and "radiusLimit" which limits how large the (visual) radius of the pie is in relation to the full radius (as calculated from the canvas dimensions) or a hard-pixel value (respectively). This allows for pushing the labels "outside" the pie.</li>
<li>Added a new option "labelHidePercent" that does not show the positioned labels of slices smaller than the specified percentage. This is to help prevent a bunch of overlapping labels from small slices.</li>
<li>Added a new option "sliceCombinePercent" that combines all slices smaller than the specified percentage into one larger slice. This is to help make the pie more attractive when there are a number of tiny slices. The options "sliceCombineColor" and "sliceCombineLabel" have also been added to change the color and name of the new slice if desired.</li>
<li>Tested in Firefox (3.0.10, 3.5b4), Internet Explorer (6.0.2900, 7.0.5730, 8.0.6001), Chrome (1.0.154), Opera (9.64), and Safari (3.1.1, 4 beta 5528.16).

<p>There are plenty of options you can set to control the precise
looks of your plot. You can control the ticks on the axes, the
legend, the graph type, etc. The idea is that Flot goes to great
lengths to provide sensible defaults so that you don't have to
customize much for a good result.</p>

/* Plugin for jQuery for working with colors.
*
* Version 1.1.
*
* Inspiration from jQuery color animation plugin by John Resig.
*
* Released under the MIT license by Ole Laursen, October 2009.
*
* Examples:
*
* $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
* var c = $.color.extract($("#mydiv"), 'background-color');
* console.log(c.r, c.g, c.b, c.a);
* $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
*
* Note that .scale() and .add() return the same modified object
* instead of making a new one.
*
* V. 1.1: Fix error handling so e.g. parsing an empty string does
* produce a color rather than just crashing.

/*
Flot plugin for showing crosshairs, thin lines, when the mouse hovers
over the plot.
crosshair: {
mode: null or "x" or "y" or "xy"
color: color
lineWidth: number
}
Set the mode to one of "x", "y" or "xy". The "x" mode enables a
vertical crosshair that lets you trace the values on the x axis, "y"
enables a horizontal crosshair and "xy" enables them both. "color" is
the color of the crosshair (default is "rgba(170, 0, 0, 0.80)"),
"lineWidth" is the width of the drawn lines (default is 1).
The plugin also adds four public methods:
- setCrosshair(pos)
Set the position of the crosshair. Note that this is cleared if
the user moves the mouse. "pos" is in coordinates of the plot and
should be on the form { x: xpos, y: ypos } (you can use x2/x3/...
if you're using multiple axes), which is coincidentally the same
format as what you get from a "plothover" event. If "pos" is null,
the crosshair is cleared.
- clearCrosshair()

- lockCrosshair(pos)
Cause the crosshair to lock to the current location, no longer
updating if the user moves the mouse. Optionally supply a position
(passed on to setCrosshair()) to move it to.
Example usage:
var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } };
$("#graph").bind("plothover", function (evt, position, item) {
if (item) {
// Lock the crosshair to the data point being hovered
myFlot.lockCrosshair({ x: item.datapoint[0], y: item.datapoint[1] });

Free the crosshair to move again after locking it.

/*
Flot plugin for computing bottoms for filled line and bar charts.
The case: you've got two series that you want to fill the area
between. In Flot terms, you need to use one as the fill bottom of the
other. You can specify the bottom of each data point as the third
coordinate manually, or you can use this plugin to compute it for you.
In order to name the other series, you need to give it an id, like this
var dataset = [
{ data: [ ... ], id: "foo" } , // use default bottom
{ data: [ ... ], fillBetween: "foo" }, // use first dataset as bottom
];
$.plot($("#placeholder"), dataset, { line: { show: true, fill: true }});
As a convenience, if the id given is a number that doesn't appear as
an id in the series, it is interpreted as the index in the array
instead (so fillBetween: 0 can also mean the first series).
Internally, the plugin modifies the datapoints in each series. For
line series, extra data points might be inserted through
interpolation. Note that at points where the bottom line is not
defined (due to a null point or start/end of line), the current line
will show a gap too. The algorithm comes from the jquery.flot.stack.js
plugin, possibly some code could be shared.

/*
Flot plugin for plotting images, e.g. useful for putting ticks on a
prerendered complex visualization.
The data syntax is [[image, x1, y1, x2, y2], ...] where (x1, y1) and
(x2, y2) are where you intend the two opposite corners of the image to
end up in the plot. Image must be a fully loaded Javascript image (you
can make one with new Image()). If the image is not complete, it's
skipped when plotting.
There are two helpers included for retrieving images. The easiest work
the way that you put in URLs instead of images in the data (like
["myimage.png", 0, 0, 10, 10]), then call $.plot.image.loadData(data,
options, callback) where data and options are the same as you pass in
to $.plot. This loads the images, replaces the URLs in the data with
the corresponding images and calls "callback" when all images are
loaded (or failed loading). In the callback, you can then call $.plot
with the data set. See the included example.
A more low-level helper, $.plot.image.load(urls, callback) is also
included. Given a list of URLs, it calls callback with an object
mapping from URL to Image object when all images are loaded or have
failed loading.
Options for the plugin are
series: {
images: {
show: boolean
anchor: "corner" or "center"
alpha: [0,1]
}
}
which can be specified for a specific series
$.plot($("#placeholder"), [{ data: [ ... ], images: { ... } ])
Note that because the data format is different from usual data points,
you can't use images with anything else in a specific data series.
Setting "anchor" to "center" causes the pixels in the image to be
anchored at the corner pixel centers inside of at the pixel corners,
effectively letting half a pixel stick out to each side in the plot.
A possible future direction could be support for tiling for large
images (like Google Maps).

/*
Flot plugin for adding panning and zooming capabilities to a plot.
The default behaviour is double click and scrollwheel up/down to zoom
in, drag to pan. The plugin defines plot.zoom({ center }),
plot.zoomOut() and plot.pan(offset) so you easily can add custom
controls. It also fires a "plotpan" and "plotzoom" event when
something happens, useful for synchronizing plots.
Options:
zoom: {
interactive: false
trigger: "dblclick" // or "click" for single click
amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out)
}
pan: {
interactive: false
cursor: "move" // CSS mouse cursor value used when dragging, e.g. "pointer"
frameRate: 20
}
xaxis, yaxis, x2axis, y2axis: {
zoomRange: null // or [number, number] (min range, max range) or false
panRange: null // or [number, number] (min, max) or false
}
"interactive" enables the built-in drag/click behaviour. If you enable
interactive for pan, then you'll have a basic plot that supports
moving around; the same for zoom.
"amount" specifies the default amount to zoom in (so 1.5 = 150%)
relative to the current viewport.
"cursor" is a standard CSS mouse cursor string used for visual
feedback to the user when dragging.
"frameRate" specifies the maximum number of times per second the plot
will update itself while the user is panning around on it (set to null
to disable intermediate pans, the plot will then not update until the
mouse button is released).
"zoomRange" is the interval in which zooming can happen, e.g. with
zoomRange: [1, 100] the zoom will never scale the axis so that the
difference between min and max is smaller than 1 or larger than 100.
You can set either end to null to ignore, e.g. [1, null]. If you set
zoomRange to false, zooming on that axis will be disabled.
"panRange" confines the panning to stay within a range, e.g. with
panRange: [-10, 20] panning stops at -10 in one end and at 20 in the
other. Either can be null, e.g. [-10, null]. If you set
panRange to false, panning on that axis will be disabled.
Example API usage:
plot = $.plot(...);
// zoom default amount in on the pixel (10, 20)
plot.zoom({ center: { left: 10, top: 20 } });
// zoom out again
plot.zoomOut({ center: { left: 10, top: 20 } });
// zoom 200% in on the pixel (10, 20)
plot.zoom({ amount: 2, center: { left: 10, top: 20 } });
// pan 100 pixels to the left and 20 down
plot.pan({ left: -100, top: 20 })
Here, "center" specifies where the center of the zooming should
happen. Note that this is defined in pixel space, not the space of the
data points (you can use the p2c helpers on the axes in Flot to help
you convert between these).
"amount" is the amount to zoom the viewport relative to the current
range, so 1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is
70% (zoom out). You can set the default in the options.

/*
Flot plugin for rendering pie charts. The plugin assumes the data is
coming is as a single data value for each series, and each of those
values is a positive value or zero (negative numbers don't make
any sense and will cause strange effects). The data values do
NOT need to be passed in as percentage values because it
internally calculates the total and percentages.
* Created by Brian Medendorp, June 2009
* Updated November 2009 with contributions from: btburnett3, Anthony Aragues and Xavi Ivars
* Changes:
2009-10-22: lineJoin set to round
2009-10-23: IE full circle fix, donut
2009-11-11: Added basic hover from btburnett3 - does not work in IE, and center is off in Chrome and Opera
2009-11-17: Added IE hover capability submitted by Anthony Aragues
2009-11-18: Added bug fix submitted by Xavi Ivars (issues with arrays when other JS libraries are included as well)
Available options are:
series: {
pie: {
show: true/false
radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
offset: {
top: integer value to move the pie up or down
left: integer value to move the pie left or right, or 'auto'
},
stroke: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
width: integer pixel width of the stroke
},
label: {
show: true/false, or 'auto'
formatter: a user-defined function that modifies the text/style of the label text
radius: 0-1 for percentage of fullsize, or a specified pixel length
background: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
opacity: 0-1
},
threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
},
combine: {
threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
label: any text value of what the combined slice should be labeled
}
highlight: {
opacity: 0-1
}
}
}
More detail and specific examples can be found in the included HTML file.

Flot plugin for automatically redrawing plots when the placeholder

It works by listening for changes on the placeholder div (through the

There are no options. If you need to disable the plugin for some
plots, you can just fix the size of their placeholders.

/*
Flot plugin for selecting regions.
The plugin defines the following options:
selection: {
mode: null or "x" or "y" or "xy",
color: color
}
Selection support is enabled by setting the mode to one of "x", "y" or
"xy". In "x" mode, the user will only be able to specify the x range,
similarly for "y" mode. For "xy", the selection becomes a rectangle
where both ranges can be specified. "color" is color of the selection
(if you need to change the color later on, you can get to it with
plot.getOptions().selection.color).
When selection support is enabled, a "plotselected" event will be
emitted on the DOM element you passed into the plot function. The
event handler gets a parameter with the ranges selected on the axes,
like this:
placeholder.bind("plotselected", function(event, ranges) {
alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to)
// similar for yaxis - with multiple axes, the extra ones are in
// x2axis, x3axis, ...
});
The "plotselected" event is only fired when the user has finished
making the selection. A "plotselecting" event is fired during the
process with the same parameters as the "plotselected" event, in case
you want to know what's happening while it's happening,
A "plotunselected" event with no arguments is emitted when the user
clicks the mouse to remove the selection.
The plugin allso adds the following methods to the plot object:
- setSelection(ranges, preventEvent)
Set the selection rectangle. The passed in ranges is on the same
form as returned in the "plotselected" event. If the selection mode
is "x", you should put in either an xaxis range, if the mode is "y"
you need to put in an yaxis range and both xaxis and yaxis if the
selection mode is "xy", like this:
setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } });
setSelection will trigger the "plotselected" event when called. If
you don't want that to happen, e.g. if you're inside a
"plotselected" handler, pass true as the second parameter. If you
are using multiple axes, you can specify the ranges on any of those,
e.g. as x2axis/x3axis/... instead of xaxis, the plugin picks the
first one it sees.
- clearSelection(preventEvent)
Clear the selection rectangle. Pass in true to avoid getting a
"plotunselected" event.
- getSelection()
Returns the current selection in the same format as the
"plotselected" event. If there's currently no selection, the
function returns null.

/*
Flot plugin for stacking data sets, i.e. putting them on top of each
other, for accumulative graphs.
The plugin assumes the data is sorted on x (or y if stacking
horizontally). For line charts, it is assumed that if a line has an
undefined gap (from a null point), then the line above it should have
the same gap - insert zeros instead of "null" if you want another
behaviour. This also holds for the start and end of the chart. Note
that stacking a mix of positive and negative values in most instances
doesn't make sense (so it looks weird).
Two or more series are stacked when their "stack" attribute is set to
the same key (which can be any number or string or just "true"). To
specify the default stack, you can set
series: {
stack: null or true or key (number/string)
}
or specify it for a specific series
$.plot($("#placeholder"), [{ data: [ ... ], stack: true }])
The stacking order is determined by the order of the data series in
the array (later series end up on top of the previous).
Internally, the plugin modifies the datapoints in each series, adding
an offset to the y value. For line series, extra data points are
inserted through interpolation. If there's a second y value, it's also
adjusted (e.g for bar charts or filled areas).
