please find attached a patch to visualise 3D histograms as fixed-size
coloured boxes. This can be useful in some circumstances to help the
eye. As I was not quite happy with the color scale already existing, I
added a "natural" ("hot-to-cold") scale for this which I find a bit more
intuive to interpret.
Thanks for writing this extremely nice tool in python !!!
PS: the patch is against paida-3.2.1_2.9
