Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Artist class contains Abstract base class for objects that render into a FigureCanvas. All visible elements in a figure are subclasses of Artist.
Matplotlib.artist.Artist.findobj() Method
The findobj() method in artist module of matplotlib library is used to return find artist objects.
Syntax: Artist.findobj(self, match=None, include_self=True)
Parameters: This method accepts the following parameters.
- match : This parameter is the filter criterion for the matches. It default value is None.
- include_self : This parameter include self in the list to be checked for a match.
Returns: This method return artists(list of Artist).
Below examples illustrate the matplotlib.artist.Artist.findobj() function in matplotlib:
Example 1:
# Implementation of matplotlib function from matplotlib.artist import Artist import matplotlib.pyplot as plt from matplotlib.lines import Line2D import numpy as np from numpy.random import rand fig, ax2 = plt.subplots() ax2.bar(range(10), rand(10), picker = True) print("Value return : \n", *list(Artist.findobj(ax2)), sep ="\n") plt.title("""matplotlib.artist.Artist.findobj() function Example""", fontweight="bold") plt.show() |
Output:
