Matplotlib.pyplot.cla() in Python

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface. There are various plots which can be used in Pyplot are Line Plot, Contour, Histogram, Scatter, 3D Plot, etc.

matplotlib.pyplot.cla() Function

The cla() function in pyplot module of matplotlib library is used to clear the current axes.
Syntax:

matplotlib.pyplot.cla()

Below examples illustrate the matplotlib.pyplot.cla() function in matplotlib.pyplot:

Example 1:

# Implementation of matplotlib function
import matplotlib.pyplot as plt

plt.plot([1, 2, 3, 4], [16, 4, 1, 8])

plt.cla()
plt.title('matplotlib.pyplot.cla Example')
plt.show()

Output:

Example 2:

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt

t = np.linspace(0.0, 2.0, 201)
s = np.sin(2 * np.pi * t)

fig, [ax, ax1] = plt.subplots(2, 1)

ax.set_ylabel('y-axis')
ax.plot(t, s)
ax.grid(True)

ax1.set_ylabel('y-axis')
ax1.set_xlabel('x-axis')
ax1.plot(t, s)
ax1.grid(True)
ax1.cla()

fig.suptitle('matplotlib.pyplot.cla Example')
plt.show()

Output:
