Matplotlib是Python中的一個庫，它是數字的-NumPy庫的數學擴展。軸類包含大多數圖形元素：Axis，Tick，Line2D，Text，Polygon等，並設置坐標係。 Axes實例通過callbacks屬性支持回調。
matplotlib.axes.Axes.get_contains()函數
matplotlib庫的axes模塊中的Axes.get_contains()函數用於返回藝術家的自定義包含函數。
用法： Axes.get_contains(self)參數：此方法不接受任何參數。
返回：此方法返回藝術家的自定義包含函數。
以下示例說明了matplotlib.axes中的matplotlib.axes.Axes.get_contains()函數：
範例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()輸出：
範例2：
