Extension:GoogleCharts

Purpose
Provides a simple interface for embedding GoogleCharts.

One notable feature of this extension comes from the fact that the native GoogleCharts formatting language is almost entirely untouched and transparent; this allows for very easy forward compatibility.

gchart parser function

 * each parameter must be separated by an &
 * alternate text is the text displayed if the chart can not be loaded
 * alternate text is the text displayed if the chart can not be loaded

gchart_pipe parser function
Many optional parameters of the GoogleCharts must be separated with the pipe | character. This character bears syntaxical meaning in MediaWiki and thus must be accounted for in a special way. The use of the parser function gcharts_pipe solves this issue.


 * Each parameter must be coma separated and the produced output parameter list will be pipe | separated.
 * Each parameter must be coma separated and the produced output parameter list will be pipe | separated.
