Hello,
I am generating contour plots with OpenDX where the min and max values
of the
colormap does not match the min and max values of the data. (e.g.
colormap
range is from 0 to 20, but data values can be lower than 0 and higher
than 20)
Is there a possibility to give those out of range data points the
minimum / maximum
color of the colormap instead of not coloring the points at all ? There
is such a feature
for AutoColor (at least for one limit) but I have to use COLOR and
COLORMAP.
Thanks for any help ...

Of course. Don't data-drive the Colormap, so it won't auto-reset to a
changing input range, then set whatever min and max you always want.
Then add two control points to the HUE curve (double-click). Drag one
all the way to the left so you have a vertical line from "good max"
up to "real max". Same for min except drag to right to make a
vertical line. Result is a roughly "S" or "Z" shaped curve (standing
on one end).
Note that the curve shape will remain but the values it maps to will
change if you data-drive and the range changes. This is rarely
desirable.
