[Zope] ZGDChart - Passing parameters

[Igor Leturia]

  Hi all!

  I am using ZGDChart to draw a chart, and I use a Data Method to obtain
the values for the chart. The problem is I want to pass some parameters
to the Data Method, and I can't get it right. I put the parameters in
the REQUEST object and then I include <dtml-var chart>, but it gives me
an error.

  Any ideas?
