I'm using matplotlib to generate some graphs, I wanted to have a bigger font for the axis scale so I used :
font = {'size' : 22}
matplotlib.rc('font', **font)
This affected my Legends size as in the figure:

Is there anyway to control the size of mpatches.Patch() text ?
Idealis in the legend. Do you only want to change the size of one of the legend labels? Please also add a minimal reproducible example.
