Exportgraphics does only export black images from UIAxes
显示 更早的评论
Hello.
I've been working on an app and I want to export the content of some UIAxes. This results only in black images.
To explain further:
plot(gca, rand(1, 100))
exportgraphics(gca, 'kajsdfgh.png')
gives what expected, a random plot. But
fig = uiaxes;
plot(fig, rand(1, 100))
exportgraphics(fig, 'ydklfg.png')
only returns a black image.
I'm using R2023b and I've been using this approach since some time, so it should work. Has there been a change in the default settings for UIAxes or exportgraphics or what is going on?
Thanks in Advance.
Edit: With further testing I realized, that it's not the exportgraphics with the problem, but the plot is just not happening.
Edit2: I've updated to Update 6 and the problem still persists.
Edit3: It works as expected on R2022a, on the same PC.

When I run this code (from the command window), it all works fine (Windows 10, MATLAB R2023b Update 6). See attached image for result.
fig = uiaxes;
plot(fig, rand(1, 100))
exportgraphics(fig, 'ydklfg.png')
I know this is fairly obvious, but maybe trying restarting and/or updating both your OS and MATLAB.

Hi Adrian, thanks for updating and testing further. I would say to double check your UIAxes settings, but it's interesting that's it's working fine on R2022a for you...
I made a very simple app (attached) to try replicate your situation and it all works fine, maybe have a go at running it yourself.
