What can this extension do?[edit]

The pChartWiki feature produces an embedded image from wikitext, much in the same way as Erik Zachte's EasyTimeline. It works as a wrapper for the pChart php class (Version 1.27d), http://pchart.sourceforge.net/

What isn't in this extension?[edit]

The following methods have not been carried over from the original pChart class, but that doesn't mean they wont in the future.

  • ImportFromCSV
  • drawFromPNG
  • drawFromGIF
  • drawFromJPG
  • Stroke
  • setImageMap
  • getImageMap

Usage[edit]

This code is INCOMPLETE and will only render a radar graph. It has NOT been TESTED for any vulnerabilities either.

Download instructions[edit]
