Dear All,
Is there any way to plot a contour with two different palette?
for instance in the following example dose it possible to color the data range [0,650] with only blue gradient and fill other levels with yellow color gradient?
data = cgDemoData(2)
cgcontour,data,nlevels=10

Decide which color indices you are using to fill the contours so you can
tell cgContour about them (with the C_COLORS keyword), then load
whatever colors you like into those indices. Job done!
Cheers,
