Set the color of the axes per default to black (instead of dark gray)?

62 views (last 30 days)
I am using
%#!/bin/rm
clc
clear
set(groot,'DefaultFigureGraphicsSmoothing','off') %not blurry function (circles)
set(groot, 'DefaultAxesFontSmoothing', 'off'); %not blurry axes-text-labels
close all;
fig=figure;
scatter((1:20),rand(1,20),'k'); %# example from https://de.mathworks.com/help/matlab/ref/figure.html
print('-dpng','grayAxes.png');
set(gca,'XColor','k','YColor','k');
print('-dpng','blackAxes.png');
close all force; %# https://de.mathworks.com/support/bugreports/1812836
Can I set
set(gca,'XColor','k','YColor','k');
as a default for all figures ( a: for all figures in a document on every computer ; b: for all figures created on my computer)?

Try putting this in your startup.m file
set(groot,{'DefaultAxesXColor','DefaultAxesYColor','DefaultAxesZColor'},{'k','k','k'})
Test:
axh = axes;
axh.XAxis.Color

In my case (Linux) it was in my home-directory under ~/Documents/MATLAB , on Windows it is in `%userprofile%/Documents/MATLAB`.

I'd try it with:
set(groot, 'DefaultAxesXColor', [0,0,0], ...
'DefaultAxesYColor', [0,0,0], ...
'DefaultAxesZColor', [0,0,0])

Sorry for this offtopic, but @Jan: I assume with Greasemonkey (Firefox) or Tampermonkey (Chrome) you can fix this locally on your browser.
