Pivot and jfreechart

Hi,
I'm starting with Pivot and for us jfreechart is very important.
I've playing with the demo, and with the provider pivot-jfree-1.5. It looks
well, but I need not just a static chart.
Do anyone know how to represent  a dynamic chart(like memory usage, the
example shown in jfreechart library)  or any other type of dynamic chart in
PIVOT?

Thanks.

I just added an example that demonstrates this to the pivot-jfree project. It produces the same pie chart shown in the other example, but does so programmatically rather than in WTKX:

http://code.google.com/p/pivot-jfree/source/browse/trunk/demos/src/biz/ixnay/pivot/demos/charts/jfree/dynamic_data_demo.wtkx

You can see the result here:

Hope this helps,

Charts are data driven, just like lists, tables, and trees. If you modify the underlying data model (i.e. the value you passed to setChartData()), the chart will update to reflect the current state of the data.
