PlotKit

PlotKit is a Javascript graph plotting library. It is aimed at web applications that require plotting series of data in modern web browsers.

PlotKit requires MochiKit. (1.3 or higher)

PlotKit supports both HTML Canvas and SVG, along with an emulated canvas for Internet Explorer.

PlotKit is easily extensible to include other rendering engines, styles and layouts. Please pursue the documentation for more information.

PlotKit is licensed under the BSD License, so you can include it in your free or commercial applications without worrying.

PlotKit Components

Base : Common functionality that is used in other classes, including default styles.
Layout : The default chart layout engine, supports bar, line and pie charts.
Renderer: Customising the look of the output

CanvasRenderer: Basic renderer using an HTML Canvas.
SVGRenderer: Basic renderer using SVG.
SweetCanvasRenderer: Customised Renderer that builds on CanvasRenderer to provide nicer looking charts.
SweetSVGRenderer: Customised renderer that builds on SVGRenderer to provide nicer looking charts.

PlotKit Quick Start - A thorough quick start to getting charts working for Safari, Mozilla, Firefox, Opera and IE.
SVG/Canvas Browser Support Status - Quirks about browser support that you should know about.
Simple Canvas Demo - Very basic Canvas demo all contained in an HTML file.
Simple SVG Demo - Very basic SVG demo all contained in an HTML file.

Make Sweet{Canvas/SVG}Renderers respect shouldFill.
Fixed ignoring of maximum x and y values when setting xAxis/yAxis.
Fixed typo for calculating yrange in Layout.js (thanks to HubrisSonic).
Changed SweetCanvasRenderer to use axisLineColor for drawing lines over background (thanks to HubrisSonic).
Fixed bug in y-axis tick drawing (thanks to Cliff).
Fixed x-axis calculation bug when xAxisIsZero is false (thanks to Loic Jeannin)
Fixed xTicks drawing that exceed the bounds of the chart (thanks to Cliff)

Fixed some redraw issues with clear()
Replaced IECanvas.HTC with ExplorerCanvas
Added auto import and packed versions just like MochiKit.
Added horizontal bar chart rendering mode.
Added awareness of prototype.js and workaround Array/Object mutilation issues with MochiKit.
Added EasyPlot for single line plotting with Ajax support.
More tests, dynamic charting and quickstart demos.

AutoSelectRenderer, automatically choose Canvas or SVG by auto detecting browser support.
