Matplotlib.figure.Figure.clear() in Python

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The figure module provides the top-level Artist, the Figure, which contains all the plot elements. This module is used to control the default spacing of the subplots and top level container for all plot elements. The clear() method figure module of matplotlib library is used to Clear the figure.

Syntax: clear(self, keep_observers=False) Parameters: This accept the following parameters that are described below:

• keep_observers: This parameter is the boolean value.

Returns: This method does not return any value.

Below examples illustrate the matplotlib.figure.Figure.clear() function in matplotlib.figure: Example 1: Python3

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
    
fig, ax = plt.subplots()
ax.set_xlabel('x-axis')
ax.set_ylabel('y-axis')
ax.plot([1, 2, 3])
ax.grid(True)
fig.clear(True)
 
fig.suptitle('matplotlib.figure.Figure.clear() \
function Example\n\n', fontweight ="bold")
plt.show()

Output: Example 2: Python3

# 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, 
                              sharex = True)
 
ax.set_ylabel('y-axis')
ax.plot(t, s)
ax.grid(True)
ax.set_title('Sample Example',
             fontsize = 12,
             fontweight ='bold')
 
ax1.set_ylabel('y-axis')
ax1.plot(t, s)
ax1.grid(True)
fig.clear(False)
 
fig.suptitle('matplotlib.figure.Figure.clear() \
function Example\n\n', fontweight ="bold")
plt.show()

Output:
