Python Matplotlib.axes.Axes.get_picker()用法及代碼示例

Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。軸類包含大多數圖形元素:Axis,Tick,Line2D,Text,Polygon等,並設置坐標係。 Axes實例通過callbacks屬性支持回調。

matplotlib.axes.Axes.get_picker()函數

matplotlib庫的axiss模塊中的Axes.get_picker()函數用於返回藝術家的選擇行為。

用法: Axes.get_picker(self)


參數:此方法不接受任何參數。

返回:此方法是藝術家的挑選行為。

以下示例說明了matplotlib.axes中的matplotlib.axes.Axes.get_picker()函數:

範例1:

#Implementation of matplotlib function 
import numpy as np 
np.random.seed(19680801) 
import matplotlib.pyplot as plt 
  
  
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(ax.get_picker()), 
        fontweight = "bold", 
        fontsize=18) 
     
fig.suptitle('matplotlib.axes.Axes.get_picker() function \ 
Example', fontweight="bold") 
  
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
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(ax.get_picker()), 
        fontweight = "bold", 
        fontsize = 18) 
    
fig.suptitle('matplotlib.axes.Axes.get_picker()\ 
function Example', fontweight ="bold") 
  
plt.show()

輸出:
