Matplotlib.axes.Axes.get_clip_box() 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.get_clip_box() Function

The Axes.get_clip_box() function in axes module of matplotlib library is used to get the clipbox.

Syntax: Axes.get_clip_box(self)

Parameters: This method does not accepts any parameter.

Returns: This method return the the animated state.

Below examples illustrate the matplotlib.axes.Axes.get_clip_box() function in matplotlib.axes:

Example 1:




# Implementation of matplotlib function
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:
    e.set_clip_box(ax.bbox)
    print(e.get_clip_box())
    e.set_alpha(0.1)
    ax.add_artist(e)
   
plt.xlim(-1, 5)
plt.ylim(-1, 5)
  
fig.suptitle('matplotlib.axes.Axes.get_clip_box() \
function Example\n\n', fontweight ="bold")
  
plt.show()

Output:

Example 2:




# Implementation of matplotlib function
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)
    e.set_clip_box(ax.bbox)
    e.set_alpha(np.random.rand())
    e.set_facecolor(np.random.rand(4))
    if x<2:
        print(e.get_clip_box())
        x+= 1
     
ax.set_xlim(3, 7)
ax.set_ylim(3, 7)
  
fig.suptitle('matplotlib.axes.Axes.get_clip_box()\
 function Example\n\n', fontweight ="bold")
  
plt.show()

Output:
