Python Matplotlib.axis.Axis.get_children()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_children()函数

matplotlib库的axis模块中的Axis.get_children()函数用于获取此Artist的子Artist的列表。

用法： Axis.get_children(self) 
 

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

范例1：

# Implementation of matplotlib function 
from matplotlib.axis import Axis 
import matplotlib.pyplot as plt   
from matplotlib.lines import Line2D   
import numpy as np   
from numpy.random import rand   
       
      
fig, ax2 = plt.subplots()   
       
ax2.bar(range(10), rand(10), picker = True)   
    
print("List of the child Artists of this Artist \n",   
      *list(ax2.get_children()), sep ="\n") 
  
fig.suptitle("""matplotlib.axis.Axis.get_children() 
function Example\n""", fontweight ="bold")   
    
plt.show()

输出：

List of the child Artists of this Artist
