Matplotlib.axes.Axes.set_zorder() in Python

  • Last Updated : 30 Apr, 2020

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.set_zorder() Function

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:




# 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:




# 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:
