why does my colorbar have lines in it?

Question

Edit: Since this seems to be a popular post, here\'s the solution that seems to be working well for me. Thanks @gazzar and @mfra.

cbar.solid         


        

Answer 1

I generally prefer to rasterize the colorbar contents to avoid this issue using Eric Firing's advice here by adding the following line.

cbar.solids.set_rasterized(True) 

This workaround supposedly fails for images with transparency, but for most normal cases it produces the desired result.
