matplotlib pyplot: subplot size

Question

If I plot a single graph as below, it will be of size (x * y).

import matplotlib.pyplot as plt
plt.plot([1, 2], [1, 2])

However, if I plot 3 sub-graphs in the same row, each of them will be of size ((x / 3) * y).

fig, ax = plt.subplots(1, 3, sharey = True)
for i in range(3):
    ax[i].plot([1, 2], [1, 2])

How can I obtain these 3 subplots, each of which is of size (x * y)?

Thanks. I was thinking if there's a way to specify that i'd like to retain its original size, instead of specifying the size. — goldfrapp04

The figure object has a default size that does not know about the number of subplots. You can change the figure size when you make the figure to suit your needs though.

import matplotlib.pyplot as plt

nx = 3
ny = 1

dxs = 8.0
dys = 6.0

fig, ax = plt.subplots(ny, nx, sharey = True, figsize=(dxs*nx, dys*ny) )
for i in range(nx):
    ax[i].plot([1, 2], [1, 2])
