Matplotlib.axes.Axes.set_zorder() 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. The Axes.set_zorder() function in axes module of matplotlib library is used to set the zorder for the artist.

Syntax: Axes.set_zorder(self, level) Parameters: This method accepts only one parameters.

• level: This parameter contains the float value.

Returns: This method does not return any value.

Below examples illustrate the matplotlib.axes.Axes.set_zorder() function in matplotlib.axes: Example 1: Python3

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
 
d = np.arange(100).reshape(10, 10)
xx, yy = np.meshgrid(np.arange(11), np.arange(11))
 
fig, ax = plt.subplots()
 
ax.set_aspect(1)
m = ax.pcolormesh(xx, yy, d)
m.set_zorder(-15)
 
fig.suptitle('matplotlib.axes.Axes.set_zorder() function\
 Example', fontweight ="bold")

plt.show()

Output: Example-2: Python3

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
 
xx = np.random.rand(16, 30)
 
fig, (ax3, ax4) = plt.subplots(1, 2)
 
m = ax3.pcolor(xx)
 
ax3.set_title("No Zorder value ")
 
m = ax4.pcolor(xx)
m.set_zorder(-20)

ax4.set_title("Zorder Value : -20")
 
fig.suptitle('matplotlib.axes.Axes.set_zorder() \
function Example', fontweight ="bold")

plt.show()

Output:
