how to set axis range matplotlib

# For a given y=time-dependent variable, x=time
fig, ax = plt.subplots(figsize=(12, 6))

ax.plot(y, label='y')
#'lower' is lower limit of the range you wanna set
#'upper' is upper limit of the range you wanna set
plt.xlim(lower, upper)

python plot range

import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure(figsize=(12, 6))

x = np.arange(0, 10, 0.1)
y = np.sin(x)
z = np.cos(x)

ax = fig.add_subplot(121)
ax2 = fig.add_subplot(122)

ax.set_title('Full view')
ax.plot(y, color='blue', label='Sine wave')
ax.plot(z, color='black', label='Cosine wave')

ax2.set_title('Truncated view')
ax2.plot(y, color='blue', label='Sine wave')
ax2.plot(z, color='black', label='Cosine wave')

ax2.set_xlim([25, 50])

plt.show()
