hi
I tried the example u suggested,but I could not find DemoDatasetFactory and also ExtendedStackedBarRenderer().

Any suggestions??

Divya

[koldy]

just click on DemoDatasetFactory in the code and it will search the references,the last result will give u the source code of DemoDatasetFactory class
and in the case of ExtendedStackedBarRenderer
just click on it and the first result will give u the code of ExtendedStackedBarRenderer class.
