Hi Max,

I'm glad to know it solved your problem.
Infact, drawing the a 3d slice needs 6 drawing processes, when a plain slice needs only one call to Gdi+ for drawing purposes. This is the main reason for the difference of performance we noticed.

Apart from this, your Pie chart is not usual, because it has lots of slices ( more than 80), when, for the vast majority of cases, this quantity does not exceed 15 slices.

Thanks to you for the samples that helped me solving other issues in FoxCharts.

Regards

Cesar

>>The recommended and default setting for this property is 3 steps. That means that when you detach a slice of doughnut or pie interactively, the slice detached will appear in 3 different positions till it reaches the final definitive position.
>>Notice that the whole chart image will be redrawn on each step. So, if you increase too much this value, it may take a long and undesirable time till the slice is completely detached.
