Matplotlib.artist.artist.set_clip_on()

Python matplotlib库的artist模块中的set_clip_on()方法用于设置artist是否使用裁剪。

语法:Artist.set_clip_on(self, b)

参数:该方法只接受一个参数。

• b:包含布尔值。

Returns:该方法不返回任何值。

下面的例子说明了matplotlib中的matplotlib.artist.artist.set_clip_on()函数:

示例1

# Implementation of matplotlib function
from matplotlib.artist import Artist
import matplotlib.pyplot as plt 
import numpy as np 
from matplotlib.patches import Ellipse 
    
  
delta = 45.0
    
angles = np.arange(0, 360 + delta, delta) 
ells = [Ellipse((2, 2), 5, 2, a) for a in angles] 
    
fig, ax = plt.subplots() 
    
for e in ells: 
    e.set_alpha(0.1) 
    ax.add_artist(e) 
        
ax.set_xlim(-1, 5) 
ax.set_ylim(-1, 5) 
Artist.set_clip_on(ax, b = False)
          
fig.suptitle('matplotlib.artist.Artist.set_clip_on()\
function Example', fontweight ="bold") 
  
plt.show()

输出:
