MATLAB: MATLAB Plot function, figure is acting weird

brokenfigureMATLABplotyellow

My figure that I created in MATLAB using Plot function looks like the picture.

Any idea why it is happening?

I haven't dont anything, last time it was just fine.

Thanks for the time

I don't really know what happened but when I open my MATLAB from command prompt using opengl the plot is back to normal. I tried it first on command prompt with this command:

matlab -softwareopengl

And then I set my MATLAB to be opened using opengl every time.

This is the link I got from MATLAB support team :

Controlling the OpenGL:

Just follow the step in the link.

NEW ANSWER

Somehow, setting to opengl renderer after Matlab starts causes an issue. I could replicate the bug if I do opengl software first, and then trying to plot. Switching the renderer to painters restores the dots.:

%Replicating the error like this: (Open MATLAB from start)
opengl software
Gx = figure;
x=0:1:100;
y=x.^2;
plot(x,y,'.')  %empty, no dots are showing
set(Gx, 'renderer', 'painters');  %dots reappear

Looks like setting renderer to opengl could cause that issue. To fix, you could just set default renderer to painters via:

set(0, 'defaultFigureRenderer', 'painters')

OLD ANSWER (for the figure not showing at all)

My attempt to answer this vague problem is - one computer has set the default figure visibility to off, hence it plots but does not show anything.

To check this:

get(0, 'DefaultFigureVisible')  %should be 'on'. If not, fix it.

To fix this:

set(0, 'DefaultFigureVisible', 'on')
close all %to make sure any invisible plots are closed before trying to plot again.

Actually, it was my prefs what went haywire. It is all good now.
