feat: fit_fmt and fix some formatting issues

[henryiii]

I think this fixes #167.

Also closes #159.

Awesome! Thanks for being super speedy @henryiii. 👍 Also thanks to this I now have learned about plt.setp.

[matthewfeickert]

Yeah, I agree that the "o" maker looks much better visually then the previous defaults.

[matthewfeickert]

As there is still overlap of y-axes on the test plots, can this get changed to

Suggested change

	fig, ax = plt.subplots()
	fig = plt.figure()

? That then fixes the axis overlap problem

[matthewfeickert]

...and now with me suggesting actual code and not a URL by accident. sigh.
