Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Artist class contains Abstract base class for objects that render into a FigureCanvas. All visible elements in a figure are subclasses of Artist.

matplotlib.artist.Artist.set_zorder() method

The set_zorder() method in artist module of matplotlib library is used to set the zorder for the artist.
Syntax: Artist.set_zorder(self, level) Parameters: This method accepts the following parameters.
  • level: This parameter contains the float value.
Returns: This method does not return any value.
Below examples illustrate the matplotlib.artist.Artist.set_zorder() function in matplotlib: Example 1: Python3 1==
# Implementation of matplotlib function
from matplotlib.artist import Artist  
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)

Artist.set_zorder(m, -15)

fig.suptitle('matplotlib.artist.Artist.set_zorder()\
function Example', fontweight ="bold") 

plt.show()
Output: Example 2: Python3 1==
# Implementation of matplotlib function
from matplotlib.artist import Artist  
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) 
Artist.set_zorder(m, -20) 
  
ax4.set_title("Zorder Value : -20") 

fig.suptitle('matplotlib.artist.Artist.set_zorder()\
function Example', fontweight ="bold") 

plt.show()
Output:
