matplotlib-users Mailing List for matplotlib

I think what the responders have in mind is simply outputting files in a
different format, e.g. png, which is rasterized. One alternative you might
consider is using code written by Tom Robataille called rasterized_scatter.
 It automatically rasterizes your data points. You can find it on github.

I think that 'axes.facecolor' does the job.
'figure.facecolor' changes the background of the figure outside the
plots (axes), that is the background color of the windows (which is not
visible in the Notebook).
