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

Try:

cbar = mymap.colorbar(sc, drawedges=False, location="bottom")

It is now well documented on the web (that I could find), but

*drawedges*   [ False | True ] If true, draw lines at color
              boundaries.

(pulled from matplotlib/lib/matplotlib/colorbar.py) I think by setting drawedges to True you are telling it to draw those lines.
