Python中的 Matplotlib.artist.Artist.format_cursor_data()

Matplotlib是Python中的一个库，它是 NumPy 库的数值数学扩展。 Artist 类包含呈现为 FigureCanvas 的对象的 Abstract 基类。图中所有可见元素都是 Artist 的子类。

matplotlib.artist.Artist.format_cursor_data() 方法

matplotlib 库的 Artist 模块中的 format_cursor_data () 方法用于获取数据的字符串表示形式。

Syntax: Artist.remove_callback(self, data)

Parameters: This method accepts the following parameters.

• data: This parameter is the data which is used to be used.

Returns: This method returns the string representation of data.

以下示例说明了 matplotlib 中的 matplotlib.artist.Artist.format_cursor_data()函数：

示例 1：

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.artist import Artist
       
  
np.random.seed(10**7)
geeksx = np.random.randn(10)
   
fig, ax = plt.subplots()
ax.plot(geeksx)
   
ax.text(1.5, 0.85, 
        "Value return by format_cursor_data():", 
        fontweight ="bold")
   
ax.text(0, 0.7,
        Artist.format_cursor_data(ax, data = geeksx))
         
fig.suptitle('matplotlib.artist.Artist.format_cursor_data()\
function Example', fontweight ="bold") 
  
plt.show()

输出：

示例 2：

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.artist import Artist
        
  
geeksx = np.array([24.40, 110.25, 20.05,
                   22.00, 61.90, 7.80,
                   15.00])
       
fig, ax = plt.subplots()
ax.plot(geeksx, 'go-')
    
ax.text(1, 95,
        "Value return by format_cursor_data():",
        fontweight ="bold")
  
ax.text(1.3, 85,
        Artist.format_cursor_data(ax,
                                  data = geeksx))
          
fig.suptitle('matplotlib.artist.Artist.format_cursor_data()\
function Example', fontweight ="bold") 
  
plt.show()

输出：
