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

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:

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,

These lines you are trying to change: are they on "traditional" figures, or are they on the much newer uifigure() such as are used with App Designer ?

[Shannon]

Traditional figures.

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

[Shannon]

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
