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_clip_box() method

The get_clip_box() method in artist module of matplotlib library is used to get the clipbox.

Syntax: Artist.get_clip_box(self) 

Parameters: This method does not accepts any parameter. 

Returns: This method return the animated state.

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

Example 1: 

Python3




# Implementation of matplotlib function
from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
    
 
delta = 45.0
    
angles = np.arange(0, 360 + delta, delta)
ells = [Ellipse((2, 2), 5, 2, a) for a in angles]
    
fig, ax = plt.subplots()
   
print("Value Return by get_clip_box()")
for e in ells:
    Artist.set_clip_box(e, ax.bbox)
    print(Artist.get_clip_box(e))
    e.set_alpha(0.1)
    ax.add_artist(e)
    
plt.xlim(-1, 5)
plt.ylim(-1, 5)
         
fig.suptitle('matplotlib.artist.Artist.get_clip_box() \
function Example', fontweight ="bold")
 
plt.show()


Output:

Example 2: 

Python3




# Implementation of matplotlib function
from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
   
   
NUM = 200
      
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("Value Return by get_clip_box()")
x = 0
   
for e in ells:
    ax.add_artist(e)
    Artist.set_clip_box(e, ax.bbox)
    e.set_alpha(np.random.rand())
    e.set_facecolor(np.random.rand(4))
 
    if x<2:
        print(Artist.get_clip_box(e))

ax.set_ylim(3, 7)
