Matlab scatter dots look strange

Hello, I use m_scatter (the m_map version of scatter) on Windows 10. The issue is, that my circles are not nicely filled with the corresponding value. This occurs in both m_scatter, gscatter and scatter. An example of what happens is attached to this post. Any idea where this comes from and how to solve this? Best, Anne

Hm, I've never seen that happen before. Does this help?

scatter(1, 1, 1000, 'fill')
set(gcf, 'renderer', 'painters')

Did that happen on the screen, or did it only happen when you saved to pdf or saved to image?

I find it odd that the top and right axes lines are not present, as if a different software package was being used, or as if you had saved to pdf but those parts got cut off (that is known to happen sometimes for pdf)

@Walter, I think the 'Box' property is off by default in a scatter plot.

At least, this is true for both the first plot on the documentation page and in one test I did.

Yes OCDER, that did the trick, thank you very much! The error is already visible on the screen (I zoomed in for you to make it clearer), and also in all other formats I saved it in on Windows (pdf, png, jpg). The same script on Ubuntu actually works fine, but I might have a slightly different version of Matlab there...

Cheers, Anne

Since it only happens with the default renderer (opengl) which use hardware acceleration you may want to see if updating your graphics driver helps.

Otherwise, have a look at https://www.mathworks.com/help/matlab/creating_plots/resolving-low-level-graphics-issues.html

Thanks Guillaume!
