Python Matplotlib.artist.Artist.get_picker()用法及代码示例


Matplotlib是Python中的一个库,它是数字的-NumPy库的数学扩展。 Artist类包含用于呈现到FigureCanvas中的对象的Abstract基类。图中所有可见元素都是Artist的子类。

matplotlib.artist.Artist.get_picker()方法

matplotlib库的艺术家模块中的get_picker()方法用于定义艺术家的挑选行为。

用法:Artist.get_picker(self)


参数:此方法不接受任何参数。

返回:此方法是艺术家的挑选行为。

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

范例1:

# Implementation of matplotlib function 
from matplotlib.artist import Artist 
import numpy as np  
import matplotlib.pyplot as plt  
  
  
np.random.seed(19680801)  
    
volume = np.random.rayleigh(7, size = 40)  
amount = np.random.poisson(7, size = 40)  
ranking = np.random.normal(size = 40)  
price = np.random.uniform(1, 7, size = 40)  
       
fig, ax = plt.subplots()  
       
scatter = ax.scatter(volume,  
                     amount,  
                     c = ranking,  
                     s = price * 3,  
                     vmin = -3,   
                     vmax = 3,  
                     cmap = "Spectral")  
     
legend1 = ax.legend(*scatter.legend_elements(num = 5),  
                    loc = "upper left",  
                    title = "Ranking")  
    
ax.add_artist(legend1)  
      
ax.text(8, 8, "Value return:"
        + str(Artist.get_picker(ax)),  
        fontweight = "bold",  
        fontsize = 18)  
          
fig.suptitle('matplotlib.artist.Artist.get_picker() \ 
function Example', fontweight ="bold")  
  
plt.show()

输出:

范例2:

# Implementation of matplotlib function 
from matplotlib.artist import Artist 
import numpy as np  
import matplotlib.pyplot as plt  
      
  
X = np.random.rand(10, 200)  
xs = np.mean(X, axis = 1)  
ys = np.std(X, axis = 1)  
    
fig = plt.figure()  
ax = fig.add_subplot(111)  
line, = ax.plot(xs, ys, 'go-', picker = 5)  
    
ax.set_picker(True)  
     
ax.text(0.48, 0.3, "Value return:" 
        +  str(Artist.get_picker(ax)),  
        fontweight = "bold",  
        fontsize = 18)  
          
fig.suptitle('matplotlib.artist.Artist.get_picker() \ 
function Example', fontweight ="bold")  
  
plt.show()

输出:
