@rcomer Awesome spot 👀

Works for me, tested it locally 👍

Would you mind just adding a comment above matplotlib.use("agg") to ensure that a future developer doesn't move this statement back to being before matplotlib.rcdefaults(), thanks 😀

You could even quote this PR, just to add some connective tissue...

Thanks @bjlittle, I've added that comment. Also a comment about why the rcdefaults is there for good measure.

# Standardise the figure size across matplotlib versions.
# This permits matplotlib png image comparison.
matplotlib.rcParams["figure.figsize"] = [8.0, 6.0]
