Hi,
Is there anyway to fill the area under a curve with gradient-by-value using Zedgraph? I know how to that with the symbol, bar, and segment line. But I could not do it with the are under the curve. I would like to have something like: Dark red (the color of the area under the curve) at 0, red up until "a" value. Light Green above "a" values. Dark green at and above "b" values. Something like the Gradient-by-value Zedgraph demo with symbol but now with the area under the curve. Something like the thermal chart, red=hot at certain values then lighter red->yellow->light blue->blue=cool.
I have tried the GradientZ fill type but it seems works only for symbol and bar. Not for the area under the curve
Thank you,
Anh
