Matplotlib.artist.artist.get_sketch_params()

Python matplotlib库的artist模块中的get_sketch_params()方法用于获取artist的草图参数。

语法:Artist.get_sketch_params(self)

参数:该方法不接受任何参数。

返回:该方法返回artist的草图参数。

下面的例子说明了matplotlib中.artist.artist.get_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') 
     
ax.text(0.2, 1.8, "Sketch Parameters : "
        +str(Artist.get_sketch_params(ax)),  
        fontweight ="bold")  
  
fig.suptitle('matplotlib.artist.Artist.get_sketch_params()\
function Example', fontweight ="bold") 
  
plt.show()
