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_gid() Method
The set_gid() method in artist module of matplotlib library is used to set the (group) id for the artist.
Syntax: Artist.set_gid(self, gid)
Parameters: This method accepts only one parameters.
- gid: This parameter is the string given as gid.
Returns: This method does not return any value.
Below examples illustrate the matplotlib.artist.Artist.set_gid() function in matplotlib:
Example 1:
# Implementation of matplotlib function from matplotlib.artist import Artist import numpy as np import matplotlib.pyplot as plt y, x = np.mgrid[:5, 1:6] poly_coords = [ (0.25, 2.75), (3.25, 2.75), (2.25, 0.75), (0.25, 0.75) ] fig, ax = plt.subplots() cells = ax.plot(x, y, x + y, color='green') ax.add_patch( plt.Polygon(poly_coords, color='forestgreen', alpha=0.5) ) ax.margins(x=0.1, y=0.05) ax.set_aspect('equal') for i, t in enumerate(ax.patches): Artist.set_gid(t, 'patch_% d' % i) fig.suptitle("""matplotlib.artist.Artist.set_gid() 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 fig, ax = plt.subplots() circle = plt.Circle((0, 0), 5, fc ='blue') rect = plt.Rectangle((-5, 10), 10, 5, fc ='green') ax.add_patch(circle) ax.add_patch(rect) circle_tip = ax.annotate('This is a blue circle.', xy =(0, 0), xytext =(30, -30), textcoords ='offset points', color ='w', ha ='left', bbox = dict(boxstyle ='round, pad =.5', fc =(.1, .1, .1, .92), ec =(1., 1., 1.), lw = 1, zorder = 1), ) rect_tip = ax.annotate('This is a green rectangle.', xy =(-5, 10), xytext =(30, 40), textcoords ='offset points', color ='w', ha ='left', bbox = dict(boxstyle ='round, pad =.5', fc =(.1, .1, .1, .92), ec =(1., 1., 1.), lw = 1, zorder = 1), ) for i, t in enumerate(ax.patches): Artist.set_gid(t, 'patch_% d'% i) for i, t in enumerate(ax.texts): Artist.set_gid(t, 'tooltip_% d'% i) ax.set_xlim(-30, 30) ax.set_ylim(-30, 30) ax.set_aspect('equal') fig.suptitle("""matplotlib.artist.Artist.set_gid() function Example""", fontweight="bold") plt.show() |
