Problem

I am trying to generate scientific journal compatible figures in Matplotlib. Most of the journals have specific font requirements (e.g. Times New Roman) and I find myself typing something like $\mathdefault{_x}$ instead of just ${_x}$ throughout the script, which reduces the readability of the scrpit.

Proposed solution

Is it possible to have a global setting like matplotlib.rcParams that can be set once for the entire figure?
