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

[Hartmut]

Follow-up Comment #6, bug #59589 (project octave):

I have new compiled a "fresh" dev Octave and tested this behavior, including
Rik's patch from comment #4. Result:

* The color produced with a simple call to bar(), not using any special
arguments, seems now to be compatible with Matlab. Perfect.

* But the color produced with hist() is still DIFFERENT from the color in
Matlab. (or with bar(...,'hist'))


clear, close all, clc
x = rand(1,20);
h = bar(x, 'hist'); % which I think is the same as: hist(x)
title('hist');
histcolor = get(h, 'FaceColor')


* result in Matlab:  'flat', and via Gimp on screenshot: [0.239, 0.149, 0.659]
(dark blue). 
* result in Octave (including patch from comment #4): [0 0.447 0.7410] (light
blue).

my conclusions:
* Also for hist() the compatibility to Matlab colors is now much better than
before. They both use a blueish color.
*  But hist() still produces a different (blue) color. And this seems also to
be a qualitative difference, because Octave returns 3 numbers, but Matlab just
returns the string 'flat', as property of the FaceColor.

I cannot judge if it is worth to pursue even better Matlab compatibility in
this issue. Strictly speaking this issue is NOT solved as fixed. But I
personally would already be happy with the current result.
