Python中的 Matplotlib.axis.Axis.get_offset_text()函数

Matplotlib是Python中的一个库，它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库，用于处理更广泛的 SciPy 堆栈。

matplotlib.axis.Axis.get_offset_text()函数

matplotlib库的axis模块中的Axis.get_offset_text()函数用于获取坐标轴offsetText作为Text实例。

Syntax: Axis.get_offset_text(self) 

Parameters: This method does not accepts any parameter. 
 

Return value: This method returns the axis offsetText as a Text instance. 

下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_offset_text()函数：

示例 1：

Python3

# Implementation of matplotlib function 
from matplotlib.axis import Axis  
import matplotlib.pyplot as plt 
import matplotlib.text 
     
fig, ax = plt.subplots() 
     
ax.plot([5,1], label="Label 1") 
ax.plot([3,0], label="Label 2") 
     
legend = ax.legend(loc="upper right") 
offset = matplotlib.text.OffsetFrom(legend, (1.0, 0.0))
  
ax.annotate("String - Info", 
            xy = (0,0),  
            size = 14, 
            xycoords = 'figure fraction', 
            xytext = (0,-20),  
            textcoords = offset,  
            horizontalalignment = 'right',  
            verticalalignment = 'top') 
    
fig.canvas.draw() 
fig.suptitle('Matplotlib.axis.Axis.get_offset_text()\n\
Function Example')  
ax.grid()
   
print("Value of get_offset_text() :",ax.xaxis.get_offset_text())
      
plt.show()

输出：

Value of get_offset_text() : Text(1, 24.911111111111108, '')

示例 2：

Python3

# Implementation of matplotlib function 
from matplotlib.axis import Axis  
import matplotlib.pyplot as plt 
import numpy as np 
    
    
fig, geeeks = plt.subplots() 
    
t = np.arange(0.0, 5.0, 0.001) 
s = np.cos(3 * np.pi * t) 
line = geeeks.plot(t, s, lw = 2) 
    
# Annotation 
geeeks.annotate('Local Max', xy =(3.3, 1), 
                xytext =(3, 1.8),  
                arrowprops = dict(facecolor ='green', 
                                  shrink = 0.05),) 
    
geeeks.set_ylim(-2, 2) 
fig.suptitle('Matplotlib.axis.Axis.get_offset_text()\n\
Function Example')  
geeeks.grid()
   
print("Value of get_offset_text() :",geeeks.xaxis.get_offset_text())
      
plt.show()

输出：

Value of get_offset_text() : Text(1, 0, '')
