[Octave-bug-tracker] [bug #59589] default color in bar (and hist) plots is different from Matlab

[Hartmut]

Follow-up Comment #9, bug #59589 (project octave):

I have recompiled and retested this:

* The color in the bar plot (first part of code in  comment #0) is still light
blue, and as such fully Matlab compatible as before.

* The color in the hist plot is now greenish-blueish (last part of code in
comment #0). This color is NOT the same as in Matlab, and also the property
'FaceColor' does not have the same content as in Matlab.

* hist plot in Matlab: color [0.239, 0.149, 0.659] (dark blue)
** property 'FaceColor' is 'flat'
* hist plot in dev Octave (as of Dec 4): color [0 0.569 0.541 (green-blue)
** property 'FaceColor' is 'interp'

I have no clue about the logic behind this color mess. But for me the version
before gave nicer colors (patch from comment #4), and the newest version
(patch from comment #8) does not seem to be any "better" in terms of
compatibility.
