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:
# Implementation of matplotlib function 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:
# 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) 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() |
Output:
