Matplotlib.axis.Axis.get_sketch_params() function in Python

Last Updated : 08 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.Axis.get_sketch_params() Function

The Axis.get_sketch_params() function in axis module of matplotlib library is used to get the sketch parameters for the artist.

Syntax: Axis.get_sketch_params(self)

Parameters: This method does not accepts any parameter.

Return value: This method return the sketch parameters for the artist.

Below examples illustrate the matplotlib.axis.Axis.get_sketch_params() function in matplotlib.axis:

Example 1:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt  
import matplotlib.colors as mcolors  
import matplotlib.gridspec as gridspec  
import numpy as np  
       
       
plt.rcParams['savefig.facecolor'] = "0.8"
plt.rcParams['figure.figsize'] = 6, 5
       
fig, ax = plt.subplots()  
       
ax.plot([1, 2])  
       
ax.locator_params("x", nbins = 3)  
ax.locator_params("y", nbins = 5)  
       
ax.set_xlabel('x-label')  
ax.set_ylabel('y-label')  
     
ax.text(0.2, 1.8, "Sketch Parameters : "
        +str(Axis.get_sketch_params(ax)),   
        fontweight ="bold")

fig.suptitle("""matplotlib.axis.Axis.get_sketch_params()
function Example\n""", fontweight ="bold")  
  
plt.show()

Output:
