plotting needs to configure 'linewidth' greater than default 0.5, otherwise no display of figure

Hi,

After I upgraded to R2016a, I noticed that I have to specify 'linewidth' greater than the default value 0.5 to display the plot. Otherwise, the figure is shown as empty.

For example, x=1:10; plot(x) The figure will be empty.

Similarly, x=1:10; plot(x, 'linewidth', 0.5) The plot will be empty too. But plot(x,'linewidth', 1) The figure will be displayed.

Is there somewhere that I can configure the Matlab environment variables to fix this issue?

Thanks! Jing

You appear to be running Windows.

Are you running on a high resolution display? Please check your zoom settings; https://www.mathworks.com/matlabcentral/answers/317869-display-issues-with-matlab-images-in-gui#answer_248354

Does it help to set your figure renderer to zbuf or painters?

I have a vague memory of this having shown up once before for Linux -- indeed when I read your description I thought it must be Linux until I looked at the window decoration and decided you were using MS Windows.

Unfortunately I do not seem to be able to google up whatever post it was (if indeed I am not just misremembering.)

I think it turned out to be an OpenGL driver issue. My confabulating memory is also suggesting to me it had to do with Intel HD 5000. My memory is probably lying.

You can create a startup script which runs everytime you start MATLAB automatically. To do so, place a script named startup.m inside a folder which is on the path (i.e. default MATLAB folder works just fine) with the following:

 set(0,'DefaultAxesFontSize',10,...
      'DefaultTextFontSize',12,...
      'DefaultLineLineWidth',1.5,...
      'DefaultLineMarkerSize',10));

Thanks a lot Richard!! It works!!!

set(groot,'DefaultLineLineWidth',1);

Note: I do NOT have the same issue running R2016a or R2016b on Windows 7 or 10. I've even explicitly run plot(1:10,'LineWidth',.1) and the plot looks great.

Thank you Greg for your prompt answer. I should mention that I run Matlab in on a SUSE Linux server. I don't know how it is on Windows OS. Do you know which configuration file to put "set(groot,'DefaultLineLineWidth',1);" ? Thanks!
