Matplotlib: Annotate Subplots in a Figure with A, B, C [duplicate]
If you want the annotation relative to the subplot then plotting it using ax.text seems the most convenient way to me.
Consider something like:
import numpy as npimport matplotlib.pyplot as pltimport stringfig, axs = plt.subplots(2,2,figsize=(8,8))axs = axs.flatfor n, ax in enumerate(axs): ax.imshow(np.random.randn(10,10), interpolation='none') ax.text(-0.1, 1.1, string.ascii_uppercase[n], transform=ax.transAxes, size=20, weight='bold')
