I am making a bar chart and I want two separate gradients for each bar. First I want a gradient to go from top to bottom solid red to transparent red. I want to paint over the top of that a gradient that goes from right to left, black to opaque.

So - In the bottom left we should have;

• Bottom left - Alpha 0
• Bottom right - Alpha 0
• Top left - Alpha 255 Colour Red
• Top Right - Alpha 255 Colour Black

So in effect I want to take a solid colour, add a left to right gradient to black then take the output of that and add a top to bottom gradient to transparency.

All this and I want it to be in a single brush, is this even possible?
