matplotlib.axes.axes.can_pan()

Matplotlib是Python中的一个库，它是NumPy库的数值-数学扩展。Axes包含了大多数图形元素:Axis、Tick、Line2D、Text、Polygon等，并设置坐标系。Axes的实例通过callbacks属性支持回调。

matplotlib.axes.axes.can_pan()函数

matplotlib库的Axes模块中的Axes.can_pan()函数用于检查Axes是否支持任何平移/缩放按钮功能。

语法:

Axes.can_pan(self)

参数:该方法不接受任何参数。

返回值:如果该方法支持任何平移/缩放按钮功能，则返回布尔值True。

下面的例子演示了matplotlib.axes.axes.can_pan()函数在matplotlib.axes中的作用:

示例1

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
  
     
fig, ax = plt.subplots()
ax.plot([1, 2, 3])
  
w = ax.can_pan()
# print(w)
  
ax.text(0.4, 2.75, "Value return by can_pan() function:",
        fontweight ="bold")
ax.text(0.9, 2.6, w, fontweight ="bold")
  
fig.suptitle('matplotlib.axes.Axes.can_pan() function \
Example\n\n', fontweight ="bold")
  
plt.show()

输出:

matplotlib.axes.axes.can_pan()

示例2

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import Slider, Button, RadioButtons
     
fig, ax1 = plt.subplots()
plt.subplots_adjust(bottom = 0.25)
t = np.arange(0.0, 1.0, 0.001)
a0 = 5
f0 = 3
delta_f = 5.0
s = a0 * np.sin(2 * np.pi * f0 * t)
     
ax1.plot(t, s, lw = 2, color = 'green')
ax1.set_ymargin(0.5)
  
w = ax1.can_pan()
  
ax1.text(0.2, 7.5, "Value return by can_pan() function:",
         fontweight ="bold")
ax1.text(0.47, 5.6, w, fontweight ="bold")
  
fig.suptitle('matplotlib.axes.Axes.can_pan() function\
 Example\n\n', fontweight ="bold")
  
plt.show()
