Matplotlib是Python中的一个库，它是数字的-NumPy库的数学扩展。轴类包含大多数图形元素：Axis，Tick，Line2D，Text，Polygon等，并设置坐标系。 Axes实例通过callbacks属性支持回调。
matplotlib.axes.Axes.get_contains()函数
matplotlib库的axes模块中的Axes.get_contains()函数用于返回艺术家的自定义包含函数。
用法： Axes.get_contains(self)
参数：此方法不接受任何参数。
返回：此方法返回艺术家的自定义包含函数。
以下示例说明了matplotlib.axes中的matplotlib.axes.Axes.get_contains()函数：
范例1：
# Implementation of matplotlib function
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)
for label in ax2.get_xticklabels():
label.set_picker(True)
def onpick1(event):
if isinstance(event.artist, Line2D):
thisline = event.artist
xdata = thisline.get_xdata()
ydata = thisline.get_ydata()
ind = event.ind
print('onpick1 line:',
np.column_stack([xdata[ind],
ydata[ind]]))
elif isinstance(event.artist, Rectangle):
patch = event.artist
print('onpick1 patch:', patch.get_path())
elif isinstance(event.artist, Text):
text = event.artist
print('onpick1 text:', text.get_text())
ax2.set_contains(onpick1)
ax2.text(0.5, 0.9,
"Value Return:"+ str(ax2.get_contains()),
fontweight ="bold", fontsize = 10)
fig.suptitle('matplotlib.axes.Axes.get_contains() function\
Example', fontweight ="bold")
plt.show()输出：
范例2：
