Matplotlib - Setting Limits

Matplotlib automatically arrives at the minimum and maximum values of variables to be displayed along x, y (and z axis in case of 3D plot) axes of a plot. However, it is possible to set the limits explicitly by using set_xlim() and set_ylim() functions.

In the following plot, the autoscaled limits of x and y axes are shown −

import matplotlib.pyplot as plt
fig = plt.figure()
a1 = fig.add_axes([0,0,1,1])
import numpy as np
x = np.arange(1,10)
a1.plot(x, np.exp(x))
a1.set_title('exp')
plt.show()

Now we format the limits on x axis to (0 to 10) and y axis (0 to 10000) −

import matplotlib.pyplot as plt
fig = plt.figure()
a1 = fig.add_axes([0,0,1,1])
import numpy as np
x = np.arange(1,10)
a1.plot(x, np.exp(x),'r')
a1.set_title('exp')
a1.set_ylim(0,10000)
a1.set_xlim(0,10)
plt.show()
