How do I get multiple subplots in matplotlib?

Question

I am a little confused about how this code works:

fig, axes = plt.subplots(nrows=2, ncols=2)

plt.show()

How does the fig, axes work in this case? What does it do?

Also why wouldn't this work to do the same thing:

fig = plt.figure()

axes = fig.subplots(nrows=2, ncols=2)

Answer 1

For getting multiple subplots in matplotlib you can use the below-mentioned code:-

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

ax[0, 0].plot(range(10), 'r')

ax[1, 0].plot(range(10), 'b') 

ax[0, 1].plot(range(10), 'g')

ax[1, 1].plot(range(10), 'k') 

plt.show()
