Hi,
I am using (in Matlab2018b, MacbookPro 2019 with macOS Catalina):
pcolor(xdata,ydata,zdata));
colorbar
shading interp
colormap(hsv);
colorbar
and the figure I get is a perfect 2D plot.
Now, when I want to save it (in any format, I have tried eps, pdf, png...), I get these anoying white lines you can see in the attachment.
When I copy the figure in my report the lines are even more accused.
Thanks in advance for your help.

There isn't an accepted answer, but the following question has a lot of potential pointers that might be of use.

No problem. I'm sure there must be a "nicer" way of doing it but I've ended up doing it this way hundreds of times!
