Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The figure module provides the top-level Artist, the Figure, which contains all the plot elements. This module is used to control the default spacing of the subplots and top level container for all plot elements.
matplotlib.figure.Figure.get_children() method
The get_children() method figure module of matplotlib library is used to get a list of artists contained in the figure.
Syntax: get_children(self)
Parameters: This method does not accept any parameters.
Returns: This method returns a list of artists contained in the figure.
Below examples illustrate the matplotlib.figure.Figure.get_children() function in matplotlib.figure:
Example 1:
# Implementation of matplotlib function 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) for label in ax2.get_xticklabels(): label.set_picker(True) def onpick1(event): if isinstance(event.artist, Line2D): thisline = event.artist xdata = thisline.get_xdata() ydata = thisline.get_ydata() ind = event.ind print('onpick1 line:', np.column_stack([xdata[ind], ydata[ind]])) elif isinstance(event.artist, Rectangle): patch = event.artist print('onpick1 patch:', patch.get_path()) elif isinstance(event.artist, Text): text = event.artist print('onpick1 text:', text.get_text()) print("List of the child Artists of this Artist \n", *list(fig.get_children()), sep ="\n") fig.suptitle('matplotlib.figure.Figure.get_children()\ function Example\n\n', fontweight ="bold") plt.show() |
Output:
List of the child Artists of this Artist Rectangle(xy=(0, 0), width=1, height=1, angle=0) AxesSubplot(0.125, 0.11;0.775x0.77)
Example 2:
# Implementation of matplotlib function import matplotlib.pyplot as plt import numpy as np from matplotlib.patches import Ellipse NUM = 200 ells = [Ellipse(xy = np.random.rand(2) * 10, width = np.random.rand(), height = np.random.rand(), angle = np.random.rand() * 360) for i in range(NUM)] fig, ax = plt.subplots(subplot_kw ={'aspect': 'equal'}) for e in ells: ax.add_artist(e) e.set_clip_box(ax.bbox) e.set_alpha(np.random.rand()) e.set_facecolor(np.random.rand(4)) ax.set_xlim(3, 7) ax.set_ylim(3, 7) print("List of the child Artists of this Artist \n", *list(fig.get_children()), sep ="\n") fig.suptitle('matplotlib.figure.Figure.get_children() \ function Example\n\n', fontweight ="bold") plt.show() |
Output:
List of the child Artists of this Artist Rectangle(xy=(0, 0), width=1, height=1, angle=0) AxesSubplot(0.125, 0.11;0.775x0.77)
