Matplotlib.axis.axis.set_pickradius()

matplotlib库的Axis模块中的Axis.set_pickradius()函数用于设置选择器使用的轴的深度

语法:Axis.set_pickradius(self, pickradius)

参数:该方法接受以下参数。

• pickradius:这个参数是float。

返回值:该方法不返回任何值。

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

示例1

# Implementation of matplotlib function
from matplotlib.axis import Axis
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-')
  
ax.grid()
  
ax.yaxis.set_pickradius(-3)
ax.xaxis.set_pickradius(3)
   
fig.suptitle("""matplotlib.axis.Axis.set_pickradius()
function Example\n""", fontweight ="bold")  
       
plt.show()

输出:

示例2

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np 
np.random.seed(19680801) 
import matplotlib.pyplot as plt 
        
volume = np.random.rayleigh(27, size = 100) 
amount = np.random.poisson(7, size = 100) 
ranking = np.random.normal(size = 100) 
price = np.random.uniform(1, 7, size = 100) 
        
fig, ax = plt.subplots() 
        
scatter = ax.scatter(volume * 2,  
                     amount**3, 
                     c = ranking, 
                     s = price**3, 
                     vmin = -3, 
                     vmax = 3, 
                     cmap ="Spectral")
ax.yaxis.set_pickradius(25)
ax.xaxis.set_pickradius(5)
ax.grid()
   
fig.suptitle("""matplotlib.axis.Axis.set_pickradius()
