Hi
I want to plot a patch with its vertex position coordinate and its vertex color (or alpha) data in QWTPolarItem's draw function,
but I need the renderer fill the patch automatically with interpolated vertex data.
As example, I plotted a simple triangle in MATLAB with 3 vertex and 3 different vertex color (or alpha) data, see below image carefully:

How can I do it in QWTPolar?Is there any way?

Thanks a lot.
