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:
