How to render a patch filled with interpolated vertex color(or alpha) data
sampad1370 last edited by
I Use QwtPolar Library, 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.
