"I have a pie chart and I want each piece of the pie to be able to be clicked on to disply another chart. can this be done"
Probably.
"Can you tell me how to do it"
Not without more info about how the data is set up, what you want to display for each pie segment, where the subsequent graphs should go...
Given that, even if you got this sorted, the code would require fairly extensive error checking components to avoid generating multiple verisons of the dame chart, I'd suggest you might be better off creating the secondary charts in advance, then doing something simple link having an index for each segment that provided the link...
anyway, post back with more info.
