[python] How to change the font size on a matplotlib plot

This is an extension to Marius Retegan answer. You can make a separate JSON file with all your modifications and than load it with rcParams.update. The changes will only apply to the current script. So

import json
from matplotlib import pyplot as plt, rcParams

s = json.load(open("example_file.json")
rcParams.update(s)

and save this 'example_file.json' in the same folder.

{
  "lines.linewidth": 2.0,
  "axes.edgecolor": "#bcbcbc",
  "patch.linewidth": 0.5,
  "legend.fancybox": true,

  ],
