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.set_picker() method
The set_picker() method in artist module of matplotlib library is used to define the picking behavior of the artist.
Syntax: Artist.set_picker(self, picker)
Parameters: This method accept the following parameters as discussed below:
- picker : This parameter is used to set picking behavior. This can be None or bool or float or function.
Returns: This method the picking behavior of the artist.
Below examples illustrate the matplotlib.artist.Artist.set_picker() function in matplotlib:
Example 1:
# Implementation of matplotlib function from matplotlib.artist import Artist import numpy as np import matplotlib.pyplot as plt np.random.seed( 19680801 ) volume = np.random.rayleigh( 27 , size = 40 ) amount = np.random.poisson( 7 , size = 40 ) ranking = np.random.normal(size = 40 ) price = np.random.uniform( 1 , 7 , size = 40 ) fig, ax = plt.subplots() scatter = ax.scatter(volume * 2 , amount * * 3 , c = ranking * * 3 , s = price * * 3 , vmin = - 3 , vmax = 3 , cmap = "Spectral" ) Artist.set_picker(ax, picker = 4 ) fig.suptitle('matplotlib.artist.Artist.set_picker()\ function Example', fontweight = "bold" ) plt.show() |
Output:
Example 2:
# Implementation of matplotlib function from matplotlib.artist import Artist import numpy as np import matplotlib.pyplot as plt X = np.random.rand( 10 , 200 ) xs = np.mean(X, axis = 1 ) ys = np.std(X, axis = 1 ) fig = plt.figure() ax = fig.add_subplot( 111 ) line, = ax.plot(xs, ys, 'go-' ) Artist.set_picker(ax, picker = True ) fig.suptitle('matplotlib.artist.Artist.set_picker()\ function Example', fontweight = "bold" ) plt.show() |
Output:
