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_sketch_params() method
The set_sketch_params() method in artist module of matplotlib library is used to sets the sketch parameters.
Syntax: Artist.set_sketch_params(self, scale=None, length=None, randomness=None)
Parameters: This method accepts the following parameters.
- scale: This parameter is the amplitude of the wiggle perpendicular to the source line, in pixels.
- length: This parameter is the length of the wiggle along the line, in pixels.
- randomness : This parameter is the scale factor by which the length is shrunken or expanded.
Returns: This method does not return any value.
Below examples illustrate the matplotlib.artist.Artist.set_sketch_params() function in matplotlib:
Example 1:
# Implementation of matplotlib function from matplotlib.artist import Artist 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') Artist.set_sketch_params(ax, 100, 100, 20) fig.suptitle('matplotlib.artist.Artist.set_sketch_params()\ function Example', fontweight ="bold") plt.show() |
Output:
Example 2:
