Hello Nokia Devs.
I have posted this question in numerous forums and never had a single answer, so please put your thinking hats on
I need help drawing in using VB.net in WP8 due to the absence of GDI+.
See the attached image.
Imagine that the background is black. I want the points along the polyline to be the same color as the gradient through which it (currently) passes, such that low level values appear green, high level values yellow and over max levels in red.
I think OpacityMasks might be the way to go, but the examples I have found use the DrawingGroup class which (as far as I can see) is absent from WP8.
Hope you can help.
