Matplotlib deprecation errors

[HaleySchuhl]

Start a discussion about anything you would like
Functions that are using matplotlib to plot histograms often give verbose depreciation errors. While these don't inherently harm anything they are annoying and can potentially raise the concern that something went wrong while using the function even though it is working fine. I found a way to suppress these warning messages.

import warnings
import matplotlib.cbook
warnings.filterwarnings("ignore",category=matplotlib.cbook.mplDeprecation)

Maybe this gets wrapped in a try block. Objections?

yeah, super annoying. isn't the issue plotnine though?
I filter the plotnine warnings in my scripts.

I think this will be fixed by switching the plotting backend in v4.x.
