python之从 matplotlib 散点图中恢复数据

从 matplotlib 散点图中，我正在尝试恢复点数据。考虑

from matplotlib import pyplot as plt 
import numpy as np 
fig = plt.figure() 
x = np.linspace(0.0, 1.0, 5) 
y = np.linspace(0.0, 1.0, 5) 
plt.scatter(x, y) 
 
ax = fig.get_children()[1] 
pc = ax.get_children()[2] 
for path in pc.get_paths(): 
    print 
    print('path:') 
    print(path) 
    print 
    print('segments:') 
    for vert, code in path.iter_segments(): 
        print(code, vert) 
 
plt.show() 

这产生

path: 
Path(array([[ 0.        , -0.5       ], 
       [ 0.13260155, -0.5       ],

  if self._edgecolors == str('face'): 

但我没有看到任何与实际分散输入数据相关的数据。也许这不是我需要查看的 ax.get_children()[2] 路径集合？
