Python中的 Matplotlib.artist.Artist.set_sketch_params()

Matplotlib是Python中的一个库，它是 NumPy 库的数值数学扩展。 Artist 类包含呈现为 FigureCanvas 的对象的 Abstract 基类。图中所有可见元素都是 Artist 的子类。

matplotlib.artist.Artist.set_sketch_params() 方法

matplotlib 库的艺术家模块中的set_sketch_params() 方法用于设置草图参数。

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.

以下示例说明了 matplotlib 中的 matplotlib.artist.Artist.set_sketch_params()函数：

示例 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()

输出：
