Python Matplotlib.axis.Axis.get_clip_box()用法及代码示例

Matplotlib是Python中的一个库，它是数字的-NumPy库的数学扩展。它是Python中令人惊叹的可视化库，用于数组的2D图，并用于与更广泛的SciPy堆栈配合使用。

Matplotlib.axis.Axis.get_clip_box()函数

matplotlib库的轴模块中的Axis.get_clip_box()函数用于获取剪贴板。

用法： Axis.get_clip_box(self) 
 

以下示例说明了matplotlib.axis中的matplotlib.axis.Axis.get_clip_box()函数：

范例1：

# Implementation of matplotlib function 
from matplotlib.axis import Axis 
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()   
      
print("Value Return by get_clip_box()")   
for e in ells:   
    e.set_clip_box(ax.bbox)   
    print(Axis.get_clip_box(e))   
    e.set_alpha(0.1)   
    ax.add_artist(e)   
       
plt.xlim(-1, 5)   
plt.ylim(-1, 5)   
  
fig.suptitle("""matplotlib.axis.Axis.get_clip_box() 
function Example\n""", fontweight ="bold")   
    
plt.show()

输出：
