Gradient Chart

[zerocool2k]

Hi,

I want to create a chart that has gradient color representing the actual values. For example, I have values for every point within a circle:
r = 2, angle = 10 degrees : x = 100
r = 2, angle = 30 degrees : x = 150
r = 3, angle = 50 degrees : x = 180
......
I want to display this in something similar to a pie chart but with gradient coloring.

I'm looking to do this in MFC. Is there any available codes that I can look at? Either single point color gradient or gradient blending is good (the latter is preferred of course).

TIA.

I know GTK+ has a color picker widget, so I suspect MFC and most of the others do as well.

Looks like the GDI+ has support for this:

Thanks. I will look into those.
Is there any special requirement for GDI+? (like .NET framework, etc.) because I try not to rely on those.

GDI+ is included in WinXP and later IIRC. Win2K has a free update from MS for GDI+, but no .NET dependencies are required.

what control are you using for charting?

I have not decided yet. I am still looking for a good one. Do you have any suggestion?
