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.get_children() Method

The get_children() method in artist module of matplotlib library is used to return a list of the child Artists of this Artist.

Syntax: Artist.get_children(self)

Parameters: This method does not accept any parameters.

Returns: This method return a list of the child Artists of this Artist.

Below examples illustrate the matplotlib.artist.Artist.get_children() function in matplotlib:

Example 1:




# Implementation of matplotlib function
from matplotlib.artist import Artist 
import matplotlib.pyplot as plt 
from matplotlib.lines import Line2D 
import numpy as np 
from numpy.random import rand 
     
    
fig, ax2 = plt.subplots() 
     
art = ax2.bar(range(10), rand(10), picker = True
  
print("List of the child Artists of this Artist \n"
      *list(art.get_children()), sep ="\n")
  
plt.title("""matplotlib.artist.Artist.get_children()
function Example""", fontweight="bold")
  
plt.show()


Output:

List of the child Artists of this Artist 

Rectangle(xy=(-0.4, 0), width=0.8, height=0.58236, angle=0)
Rectangle(xy=(0.6, 0), width=0.8, height=0.305497, angle=0)
Rectangle(xy=(1.6, 0), width=0.8, height=0.650615, angle=0)
Rectangle(xy=(2.6, 0), width=0.8, height=0.397435, angle=0)
Rectangle(xy=(3.6, 0), width=0.8, height=0.634406, angle=0)
Rectangle(xy=(4.6, 0), width=0.8, height=0.377936, angle=0)
Rectangle(xy=(5.6, 0), width=0.8, height=0.229145, angle=0)
Rectangle(xy=(6.6, 0), width=0.8, height=0.755452, angle=0)
Rectangle(xy=(7.6, 0), width=0.8, height=0.954083, angle=0)
Rectangle(xy=(8.6, 0), width=0.8, height=0.509706, angle=0)

Example 2:




# Implementation of matplotlib function
from matplotlib.artist import Artist 
import matplotlib.pyplot as plt 
import numpy as np 
from matplotlib.patches import Ellipse 
    
     
NUM = 20
     
ells = [Ellipse(xy = np.random.rand(2) * 10
                width = np.random.rand(), 
                height = np.random.rand(), 
                angle = np.random.rand() * 360
        for i in range(NUM)] 
     
fig, ax = plt.subplots(subplot_kw ={'aspect': 'equal'}) 
  
print("List of the child Artists of this Artist \n")
for e in ells: 
    ax.add_artist(e) 
    e.set_clip_box(ax.bbox) 
    e.set_alpha(np.random.rand()) 
    e.set_facecolor(np.random.rand(4))
      
print(*list(ax.get_children()), sep = "\n")
    
ax.set_xlim(3, 7
ax.set_ylim(3, 7
  
plt.title("""matplotlib.artist.Artist.get_children()
function Example""", fontweight="bold")
  
plt.show()


Output:
