<p>No problem Alan. Thanks for replying. I thought my issue was due to truncation. Anyhow, I had a look at the bug #16978 and, if I can, I would like to give my opinion. When min and max are the same or both zero, I expect as user to see an unique color in
the color map either red or blue. If you add an eps to the max and still show the full rgb color map, I would think immediately that there are not enough digit in the label and I would start playing with that or rescaling to find where the differences are.</p>
