Matplotlib.axis.axis.grid()

matplotlib库的Axis模块中的Axis.grid()函数用于配置网格线。

语法:Axis.grid(self, b=None，which= ‘ major ‘， **kwargs)

参数:该方法接受以下参数。

• b:可选参数，是否显示网格线。
• 该参数也是一个可选参数，它是应用更改的网格线。

返回值:该方法不返回任何值。

下面的例子说明了matplotlib.axis.axis.grid()函数在matplotlib.axis中:

示例1

# Implementation of matplotlib function 
from matplotlib.axis import Axis  
import matplotlib.pyplot as plt 
import numpy as np 
       
fig, ax = plt.subplots() 
ax.plot([1, 2, 3]) 
ax.xaxis.grid() 
    
fig.suptitle("Matplotlib.axis.Axis.grid()\
Function Example", fontsize = 12, fontweight ='bold')
  
plt.show()

输出:

示例2

# Implementation of matplotlib function 
from matplotlib.axis import Axis  
import numpy as np 
import matplotlib.pyplot as plt 
      
x = np.arange(-5, 5, 0.01) 
y1 = -3 * x*x + 10 * x + 10
y2 = 3 * x*x + x 
      
fig, [ax, ax1] = plt.subplots(2, 1,  
                              sharex = True) 
    
ax.plot(x, y1, x, y2, color ='black') 
ax.fill_between(x, y1, y2, where = y2 >y1, 
                facecolor ='green', 
                alpha = 0.8) 
    
ax.fill_between(x, y1, y2, where = y2 <= y1,  
                facecolor ='black',  
                alpha = 0.8) 
    
ax.xaxis.grid(True, color ="black") 
ax.set_title('\n Grid in X-axis', 
             fontsize = 12, fontweight ='bold') 
    
ax1.plot(x, y1, x, y2, color ='black')
