Matplotlib.axes.Axes.clear() in Python
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:
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:
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()
