Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. It is an amazing visualization library in Python for 2D plots of arrays and used for working with the broader SciPy stack.
Matplotlib.axis.Axis.set_label() Function
The Axis.set_label() function in axis module of matplotlib library is used to set the label that will be displayed in the legend.
Syntax: Axis.set_label(self, s)
Parameters: This method accepts the following parameters.
- s: This parameter is converted to a string by calling str.
Return value: This method return the picking behavior of the artist.
Below examples illustrate the matplotlib.axis.Axis.set_label() function in matplotlib.axis:
Example 1:
Python3
# Implementation of matplotlib function from matplotlib.axis import Axis import matplotlib.pyplot as plt import numpy as np from matplotlib.collections import EllipseCollection x = np.arange( 5 ) y = np.arange( 7 ) X, Y = np.meshgrid(x * * 2 , y * * 3 ) XY = np.column_stack((X.ravel(), Y.ravel())) fig, ax = plt.subplots() ec = EllipseCollection( 5 , 7 , 5 , units = 'y' , offsets = XY * 0.5 , transOffset = ax.transData, cmap = "plasma" ) ec.set_array((X * Y + X * X).ravel()) ax.add_collection(ec) ax.autoscale_view() ax.set_xlabel( 'X' ) ax.set_ylabel( 'y' ) cbar = plt.colorbar(ec) cbar.set_label( 'X + Y' ) fig.suptitle('matplotlib.axis.Axis.set_label() \ function Example\n', fontweight = "bold" ) plt.show() |
Output:
