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.cla() Function
The Axes.cla() function in axes module of matplotlib library is used to clear the current axes.
Syntax: Axes.cla(self)
Parameters: This method does not accept any parameters.
Returns:This method does not returns any values.
Below examples illustrate the matplotlib.axes.Axes.cla() function in matplotlib.axes:
Example 1:
import numpy as np
import matplotlib.pyplot as plt
np.random.seed( 19 )
data = np.random.random(( 5 , 10 , 10 ))
fig, ax = plt.subplots()
for i in range ( len (data)):
ax.cla()
ax.imshow(data[i])
ax.set_title( "Axes {}" . format (i))
plt.pause( 0.1 )
|
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 )
ax.set_ylabel( 'y-axis' )
ax.plot(t, s)
ax.grid( True )
ax.set_title( 'matplotlib.axes.Axes.cla() Example\n\n Sample Example' ,
fontsize = 12 , fontweight = 'bold' )
ax1.set_ylabel( 'y-axis' )
ax1.set_xlabel( 'x-axis' )
ax1.plot(t, s)
ax1.grid( True )
ax1.cla()
ax1.set_title('Above example with cla()\
function ', fontsize = 12, fontweight =' bold')
plt.show()
