Matplotlib is a library in Python and it is numerical ā 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_gid() Function
The Axes.get_gid() function in axes module of matplotlib library is used to get the group id.
Syntax: Axes.get_gid(self)
Parameters: This method does not accepts any parameter.
Returns: This method return the group id.
Below examples illustrate the matplotlib.axes.Axes.get_gid() function in matplotlib.axes:
Example 1:
# Implementation of matplotlib function import numpy as np import matplotlib.pyplot as plt Ā Ā Ā Ā y, x = np.mgrid[:5, 1:6] Ā Ā poly_coords = [ Ā Ā Ā Ā (0.25, 2.75), (3.25, 2.75), Ā Ā Ā Ā (2.25, 0.75), (0.25, 0.75) ] fig, ax = plt.subplots() Ā Ā Ā Ā cells = ax.plot(x, y, x + y, color ='green') Ā Ā ax.add_patch( Ā Ā Ā Ā plt.Polygon(poly_coords, color ='forestgreen', Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā alpha = 0.5) Ā Ā Ā Ā ) ax.margins(x = 0.1, y = 0.05) ax.set_aspect('equal') Ā Ā for i, t in enumerate(ax.patches): Ā Ā Ā Ā t.set_gid('patch_% d' % i) Ā Ā Ā Ā print("Value Return :", t.get_gid()) Ā Ā Ā Ā fig.suptitle('matplotlib.axes.Axes.get_gid() function\ Ā Example\n\n', fontweight ="bold") Ā Ā plt.show() |
Output:
Value Return : patch_0
