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

Matplotlib是Python中的一个库，它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库，用于处理更广泛的 SciPy 堆栈。

Matplotlib.axis.Axis.get_children()函数

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

下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_children()函数：

示例 1：

Python3
# 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()

Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt  
import numpy as np  
from matplotlib.patches import Ellipse  
      
       
NUM = 20
       
ells = [Ellipse(xy = np.random.rand(2) * 10,  
                width = np.random.rand(),  
                height = np.random.rand(),  
                angle = np.random.rand() * 360)  
        for i in range(NUM)]  
       
fig, ax = plt.subplots(subplot_kw ={'aspect': 'equal'})  
    
print("List of the child Artists of this Artist \n") 
for e in ells:  
    ax.add_artist(e)  
    e.set_clip_box(ax.bbox)  
    e.set_alpha(np.random.rand())  
    e.set_facecolor(np.random.rand(4)) 
        
print(*list(ax.get_children()), sep = "\n") 
      
ax.set_xlim(3, 7)  
ax.set_ylim(3, 7)  
  
fig.suptitle("""matplotlib.axis.Axis.get_children()
function Example\n""", fontweight ="bold")  
    
plt.show()

输出：

示例 2：

Python3 

# Implementation of matplotlib function
from matplotlib.axis import Axis

import numpy as np  
from matplotlib.patches import Ellipse  
      
       
NUM = 20

                width = np.random.rand(),  
                height = np.random.rand(),  
                angle = np.random.rand() * 360)  
        for i in range(NUM)]  
       
fig, ax = plt.subplots(subplot_kw ={'aspect': 'equal'})  
    
print("List of the child Artists of this Artist \n") 
for e in ells:  
    ax.add_artist(e)  
    e.set_clip_box(ax.bbox)  
    e.set_alpha(np.random.rand())  
    e.set_facecolor(np.random.rand(4)) 
        
print(*list(ax.get_children()), sep = "\n") 
      
ax.set_xlim(3, 7)  
ax.set_ylim(3, 7)  
  
fig.suptitle("""matplotlib.axis.Axis.get_children()
function Example\n""", fontweight ="bold")  
    
plt.show()

输出：
