0 0 1 minute read

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

matplotlib.axes.Axes.clear() Function

The Axes.clear() function in axes module of matplotlib library is used to clear the axes.

Syntax: Axes.clear(self)

Parameters: This method does not accept any parameters.

Returns:This method does not returns any values.

Below examples illustrate the matplotlib.axes.Axes.clear() function in matplotlib.axes:

Example 1:

# 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)
ax.clear()
ax.set_title('matplotlib.axes.Axes.clear() \
Example\n', fontsize = 12, fontweight ='bold')
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, sharex = True)
  
ax.set_ylabel('y-axis')
ax.plot(t, s)
ax.grid(True)
ax.set_title('matplotlib.axes.Axes.clear() Example\n\n Sample Example',
             fontsize = 12, fontweight ='bold')
  
ax1.set_ylabel('y-axis')
ax1.plot(t, s)
ax1.grid(True)
ax1.clear()
ax1.set_title('Above example with clear() \
function', fontsize = 12, fontweight ='bold')
plt.show()
