MS,

That is certainly not the expected behavior. Please report this to MathWorks Technical Support so this can be looked into. It will help if you can provide reproduction steps and information about how you are running MATLAB (startup options, platform/OS, machine configuration, etc). Since you mentioned that it was working properly until a few days ago, it might help if you are able to identify what might have changed... did you update your hardware or software? Did you change machines? ...

Thanks

Hi richard,

Thanks for the suggestion. I have made a request to MATlab team. I have not made any changes. I will check it once again

在 MATLAB Online 中打开

I didn't face this problem in R2020a update 2, however, I remember observing something like this (not exactly sure if it was exportgraphics). Have you installed update 2? Alternatively, I suggest using this excellent package by Yair on FEX: https://www.mathworks.com/matlabcentral/fileexchange/23629-export_fig. I have found that this usually gives a better output as compared to the built-in function from MATLAB. Download this and add it to MATLAB's path and run it like this

export_fig(gcf,[filenames(1:end-4),'.tiff'], '-r300');

Your exportgraphics command is correct. But have you installed update 2 for R2020a?
