Hi.
I found this very nice looking pie chart in the Gallery on your website:
I did not found this as an example shipping with TeeChart V8.04.
Can you please tell me if such a chart can be build with TeeChart in Delphi 2007?
If so, can you please send me some example code?
Best regards!

Hi marder,
Notice that some of those charts were plotted using TeeChart for .NET
v3 and some of Micrsoft .NET Framework drawing tecniques are not available
in the VCL framework.
However, I've sent to your forums registered mail an example
reproducing similar pie to the one in the gallery using TeeChart Pro v8
VCL.

Hi marder,
I think that the most probably is that your delphi's search path is still referencing some previous teechart installation packages. Could you please verify the search and the library path?

Hello,
I've upgraded the Pie in the post above to TeeChart v2010 and its new properties: BevelPercent, EdgeStyle and Transparency.
The result is quite better:
