Matplotlib.axis.axis.set_tick_params()

matplotlib库的Axis模块中的Axis.set_tick_params()函数用于设置刻度、刻度标签和网格线的外观参数。

Axis.set_tick_params(self, Axis = ‘ major ‘， reset=False， \\kw)

参数:该方法接受以下参数。

• axis:此参数用于将参数应用到哪个轴。

返回值:该方法不返回任何值。

下面的例子说明了matplotlib.axis.axis.set_tick_params()函数在matplotlib.axis中的作用:

示例1

# Implementation of matplotlib function 
import matplotlib.pyplot as plt
import numpy as np
  
t = np.arange(0.0, 2.0, 0.02)
  
fig, ax1 = plt.subplots()
  
ax1.plot(t, np.sin(4*np.pi * t))
ax1.grid(True)
ax1.set_ylim((-2, 2))
  
ax1.xaxis.set_tick_params(labelcolor='r')
ax1.yaxis.set_tick_params(labelcolor='g')
  
plt.title('matplotlib.axis.Axis.set_tick_params()\n\
function Example', fontweight ="bold") 
    
plt.show()

输出:
