I don't know if it something wanted but it's very useful for me. For
example sometime to improve the contrast between two values, I plot the
log of the image but I don't want the value of the colorbar in log but
linear or another sample (problably not good but I didn't find any other
way to do it), I want plot the data from yellow to red, I'm using the
hot colormat to do it but I didn't find any way to do the opposite so I
began by plotting the data with the normal value, I plot the colorbar
and I plot another time the opposite of the data, after with gimp I turn
the colorbar and my scale is ok.
It's bad and dirty but it's working. I didn't find any otther way to do
it properly.
