FlotChartPlugin

A JQuery based CHARTs for Foswiki

Description

Currently based on Flot 0.6

(from http://code.google.com/p/flot)

Flot is a pure Javascript plotting library for jQuery. It produces graphical plots of arbitrary datasets on-the-fly client-side.

The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming.

Although Flot is easy to use, it is also advanced enough to be suitable for Web 2.0 data mining/business intelligence purposes which is its original application.

The plugin is targeting all newer browsers. If you find a problem, please report it. Drawing is done with the <canvas> tag introduced by Safari and now available on all major browsers, except Internet Explorer where the excanvas Javascript emulation helper is used.
