Is there a way to make filled GoPolygons transparent? They are polygons with the FillSimpleGradient option.
If you wanted them completely transparent, you wouldn’t be using a Fill, so I’m guessing you want them partially transparent…
sure... if you set the colors to Color.FromArgb(A, R, G, B), the "A" is the Alpha, or the transparency level from 0 to 255.
That worked. Thanks! 
Here’s what it looks like. Doing a graph program that must display the overlap between function areas.
