Follow-up Comment #2, bug #48667 (project octave):

In general, Matlab seems to be able to assign different colormaps to different
axes of the same figure, see e.g. here [1].
This seems to have been introduced with Matlab R2014b [2].

Maybe, we could add a hidden property "__colormap__" to the axes that would be
used if it is not empty and use the "colormap" property of the figure
otherwise.
But that would probably mean that we would have to duplicate "clim" and
"climmode" (and maybe other properties?) as well.
