Help/ChartPlugin

The Chart plugin allows to easily draw simple graphs on a wiki page.

Three graph formats are possible: line, bar and pie. In pie mode, negative values are ignored.

The browser must support SVG in order graphs to be displayed. If you are using a recent browser (Firefox, Opera, Chrome, Safari) then you should see the examples.
