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.get_picker() method
The get_picker() method in artist module of matplotlib library is used to define the picking behavior of the artist.
Syntax: Artist.get_picker(self)
Parameters: This method does not accept any parameters.
Returns: This method the picking behavior of the artist.
Below examples illustrate the matplotlib.artist.Artist.get_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(7, 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, amount, c = ranking, s = price * 3, vmin = -3, vmax = 3, cmap = "Spectral") legend1 = ax.legend(*scatter.legend_elements(num = 5), loc = "upper left", title = "Ranking") ax.add_artist(legend1) ax.text(8, 8, "Value return : " + str(Artist.get_picker(ax)), fontweight = "bold", fontsize = 18) fig.suptitle('matplotlib.artist.Artist.get_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-', picker = 5) ax.set_picker(True) ax.text(0.48, 0.3, "Value return : " + str(Artist.get_picker(ax)), fontweight = "bold", fontsize = 18) fig.suptitle('matplotlib.artist.Artist.get_picker() \ function Example', fontweight ="bold") plt.show() |
Output:
