PlotKit

PlotKit is a Chart and Graph Plotting Library for Javascript. It has support for HTML Canvas and also SVG via Adobe SVG Viewer and native browser support.

PlotKit is fully documented and there is also a quick tutorial to get you started.

PlotKit is a complete rewrite of CanvasGraph. It is better structured and supported.

Changes in 0.9.1 Version:
- 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 barchart drawing with only 2 values (thanks to HubrisSonic)
- Hide pie chart labels of 0% (thanks to Attiks)
- Added optional field to addDatasetFromTable to include x-axis labels.
- Updated excanvas.js version to fix possible printing issues.

Requirements:

· MochiKit 1.3 or higher
· HTML Canvas: Safari 2+, Opera 9+, Firefox 1.5+, IE 6 (in emulated mode)
· SVG: Opera 9+, Firefox 1.5+ (see note), IE6 with Adobe SVG
· Firefox 1.5+ on Linux and Windows is supported. Firefox 1.5+ on Mac does not draw labels in SVG, so you must set axisLabelUseDiv to true if you want to have maximum compatibility.
