• It is the whole figure. It keeps track of all the child Axes.

fig = plt.figure() # an empty figure with no Axes
fig, ax = plt.subplots() # a figure with a single Axes
fig, axs = plt.subplots(2, 2) # a figure with a 2x2 grid of Axes

2. Axes

• It is the plot. It is the region of the image with the data space.

axes.Axes.set_xlim()
axes.Axes.set_ylim()
axes.Axes.set_title()
axes.Axes.set_x_label()
axes.Axes.set_y_label()
