I had a simple 2D pie chart on a page that was working fine. I converted the charttype to a 3D pie chart through code. Now the charts height increases. Eventhough i have specified the hight of the chart in the markup. Any ideas what would cause the chart to change its height. Iam pasting the markup for the chart control below if it is of any help. Also this is not 100% reproducible. Sometimes the first time the chart is generated its height is correct, but after a postback the height increasses.

i think the property you are looking for is Transform3D.Scale.
The Extent property is ignored on 3D charts.
that sounds very unusual; i don't know what would cause such a problem. can you provide a sample project or steps to reproduce?
