Indeed this would be a good solution. Without it, the math output is really 
ugly, as shown in this example. 

IIRC, this was the main reason to set the default style to 'classic' while 
upgrading to Matplotlib 2.1.
Let me stress that when using Jupyter notebooks with %display latex, it is 
nice to have exactly the same fonts in legend labels of plots as in MathJax 
outputs.

Best wishes,

Eric.

Consulting 

https://matplotlib.org/users/dflt_style_changes.html

we may keep specifically only the math font of the classic style by:

mpl.rcParams['mathtext.fontset'] = 'cm'
mpl.rcParams['mathtext.rm'] = 'serif'

and adopt the default matplotlib-2 style generally. I assume that the 
matplotlib-2 style is an improvement over the classic style in general.

Generally equations look better with the font choices in the “classic” style 
which was
the default before matplotlib-2.

Yeah, I found one thing that looks ugly on my machine:

In the 'classic' style:



In the current default style:

I looked through the documentation rebuilt with the current default style. 
It still looks great, and I find nothing ugly :-)

I am sorry to have introduced that in the upgrade to matplotlib 2.1. Hardcoding
was easier than setting the style to classic for every calls for the 
documentation.
The reports I had was that the default style from 2.1 onwards made the 
documentation
plots look ugly.

[sage-devel] Matplotlib plotting style 'classic' hardcoded to Sage

[Kwankyu Lee]

Hi,

This ticket

https://trac.sagemath.org/ticket/25799

aims to remove matplotlib style 'classic' hardcoded into Sage. This makes 
customization through the matplotlibrc file work, which fails presently.

After the ticket merged, the default matplotlib styles would be applied to 
all Sage graphics, and Sage graphics may look subtly different than what 
you have been used to. If you don't like this, then raise your voice to the 
ticket.
