I'm not quite sure what you mean by your first question, but it sounds like you are looking for something similar to the "domain" data role: http://code.google.com/apis/chart/interactive/docs/roles.html
As to your second, I don't believe there is any way to put a PieChart (or anything other than text, for that matter) inside a tooltip. You could create a Pie chart along side the main chart and link them together, though. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
