[vtkusers] Fwd: Questions about char drawing in VTK(Multi-level pie chart or ring chart)

[Lucas Lira Gomes]

Hi everyone,

i've been trying to draw a multi-level pie chart, also now as ring
chart, for a while. Although I already succeeded in drawing a common
pie chart using the vtkChartPie class, I'm completely stuck in the
multi-level part. If someone could help me by giving any tips,
snippets or suggestions, I'd be really grateful.

Ring chart / Multilevel pie chart example:

Thanks in advance, Lucas Lira Gomes.
