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 axes bounding box in display space.
Below examples illustrate the matplotlib.axes.Axes.get_window_extent() function in matplotlib.axes:
Example 1:
Python3
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),
BboxTransformTo(
TransformedBbox(
Bbox(x0=0.0, y0=0.0, x1=6.4, y1=4.8),
Affine2D(
[[100. 0. 0.]
[ 0. 100. 0.]
[ 0. 0. 1.]]))))
Example 2:
Python3
import numpy as np
import matplotlib.pyplot as plt
xx = np.random.rand( 16 , 30 )
fig, ax3 = plt.subplots()
m = ax3.pcolor(xx)
m.set_zorder( - 20 )
w = ax3.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),
BboxTransformTo(
TransformedBbox(
Bbox(x0=0.0, y0=0.0, x1=6.4, y1=4.8),
Affine2D(
[[100. 0. 0.]
[ 0. 100. 0.]
[ 0. 0. 1.]]))))
