Equal axis labels and ranges for all subplots

Question

Say I\'m plotting an image with 4 subplots like so:

import matplotlib.pyplot as plt
fig = plt.figure()

ax1 = fig.add_subplot(221)
plt.xlim(0, 10)
plt.ylim(0, 20         


        

Answer 1

I know this was posted a while ago, but for anyone seeing this post now, I would add to @zhangxaochen answer to note that in plt.subplots command also has the parameters sharex and sharey. So if you want, you could just use:

import matplotlib.pyplot as plt
fig, axes=plt.subplots(2, 2, sharex = True, sharey = True)
for ax in axes.ravel(): #ravel axes to a flattened array 
# Do plotting here
plt.show()

Answer 2

use plt.subplots:

In [36]: import matplotlib.pyplot as plt
    ...: fig, axes=plt.subplots(2, 2)
    ...: for ax in axes.ravel(): #ravel axes to a flattened array 
    ...:     ax.set_xlim(0, 10)
    ...:     ax.set_ylim(0, 20)
    ...:     ax.set_xlabel('Label_x')
    ...:     ax.set_ylabel('Label_y')
    ...: plt.show()
    ...:
