Matplotlib.axes.Axes.get_window_extent() 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_window_extent() Function

The Axes.get_window_extent() function in axes module of matplotlib library is used to return the axes bounding box in display spaced.

Syntax: Axes.get_window_extent(self, \*args, \*\*kwargs)

Here, args and kwargs are empty.
Parameters: This method does not accepts any parameters.

Returns: This method return the the axes bounding box in display space.



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

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
        
  
X = np.arange(-10, 10, 0.5)
Y = np.arange(-10, 10, 0.5)
U, V = np.meshgrid(X, Y)
    
fig, ax = plt.subplots()
ax.quiver(X, Y, U, V)
ax.invert_xaxis()
w = ax.get_window_extent()
print(str(w))
   
fig.suptitle('matplotlib.axes.Axes.get_window_extent()\
 function Example', fontweight ="bold"
  
plt.show()

Output:

TransformedBbox(
    Bbox(x0=0.125, y0=0.10999999999999999, x1=0.9, y1=0.88),
