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_clip_box()函数
matplotlib库的axiss模块中的Axes.get_clip_box()函数用于获取剪贴板。
用法： Axes.get_clip_box(self)
参数：此方法不接受任何参数。
返回：此方法返回动画状态。
以下示例说明了matplotlib.axes中的matplotlib.axes.Axes.get_clip_box()函数：
范例1：
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
delta = 45.0
angles = np.arange(0, 360 + delta, delta)
ells = [Ellipse((2, 2), 5, 2, a) for a in angles]
fig, ax = plt.subplots()
print("Value Return by get_clip_box()")
for e in ells:
e.set_clip_box(ax.bbox)
print(e.get_clip_box())
e.set_alpha(0.1)
ax.add_artist(e)
plt.xlim(-1, 5)
plt.ylim(-1, 5)
fig.suptitle('matplotlib.axes.Axes.get_clip_box() \
function Example\n\n', fontweight ="bold")
plt.show()输出：
Value Return by get_clip_box()
