Last Updated : 10 Jun, 2020

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. It is an amazing visualization library in Python for 2D plots of arrays and used for working with the broader SciPy stack.

matplotlib.axis.Tick.set_gid() Function

The Tick.set_gid() function in axis module of matplotlib library is used to set the (group) id for the artist.

Syntax: Tick.set_gid(self, gid)

Parameters: This method accepts the following parameters.

gid: This parameter is the string given as gid.

Return value: This method does not return any value.

Below examples illustrate the matplotlib.axis.Tick.set_gid() function in matplotlib.axis:
Example 1:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Tick
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='red') 
ax.add_patch( 
    plt.Polygon(poly_coords, 
                color='lightblue', 
                alpha=0.5) 
) 
   
ax.margins(x=0.1, y=0.05) 
ax.set_aspect('equal') 
   
for i, t in enumerate(ax.patches): 
    Tick.set_gid(t, 'patch_% d' % i)
