Error when trying to change the colour of a line in a figure

18 views (last 30 days)
Hello - I'm using Matlab 2017a with Ubuntu 18.04. I open Matlab using the opengl option. I'm getting the following error when I try to change the colour of a line using the GUI:
Error using matlab.ui.internal.dialog.WebColorChooser/show (line 72)
Java exception occurred:
com.mathworks.html.BrowserCreationException: com.mathworks.html.BrowserCreationException:

Is there a solution to this? I'm also having a graphics bug, I think the two could be related https://www.mathworks.com/matlabcentral/answers/342959-matlab-r2016b-graphics-bug-linux
Thanks,

Error using matlab.ui.internal.dialog.WebColorChooser/show (line 72) indicates you're using uisetcolor, and that's causing the problem - not the actual attempt to change plot line color.
See my own question regarding issues (and workarounds) with the new uisetcolor WebColorChooser.
Since you're running R2017a, try this:
setpref('Mathworks_uisetcolor','Version',1); % RESTART MATLAB

The above solution does not work but the other one that you posted did work:
s = settings;
oldcolorpicker = 'matlab.ui.internal.dialog.ColorChooser';
% For reference:
% newcolorpicker = 'matlab.ui.internal.dialog.WebColorChooser';
s.matlab.ui.dialog.uisetcolor.ControllerName.TemporaryValue = oldcolorpicker;
Thanks for your help!

I confirm that the second solutions works, as I get the error while trying to change textbox color in a figure menu. Thanks
