To keep settings throughout the current session, we can execute matplotlib.rcParams to override configuration file settings.

For instance, we can set the font size of all text in plots to 18 with the following:

matplotlib.rcParams['font.size'] = 18

Alternatively we can call the matplotlib.rc() function. As matplotlib.rc() just changes one property, to change multiple settings, we can use the function matplotlib.rcParams.update(), and pass parameters in the form of a dictionary of key-value pairs:

matplotlib.rcParams.update({'font.size': 18, 'font.family': 'serif'})
