Matplotlib.axis.axis.get_majorticklabels()

matplotlib库的Axis模块中的Axis.get_majorticklabels()函数用于获取主要标记的文本实例列表。

语法:Axis.get_majorticklabels(self)

参数:该方法不接受任何参数。

返回值:该方法返回主要ticklabel的Text实例列表。

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

示例1

# Implementation of matplotlib function 
import numpy as np
from matplotlib.axis import Axis  
import matplotlib.pyplot as plt
import matplotlib.ticker as ticker
     
np.random.seed(19680801)
  
fig, ax = plt.subplots()
ax.plot(100*np.random.rand(20))
  
formatter = ticker.FormatStrFormatter('%1.2f')
Axis.set_major_formatter(ax.yaxis, formatter)
  
print("Value of get_major_ticks() :")
for i in ax.xaxis.get_majorticklabels():
    print(i)
      
plt.title("Matplotlib.axis.Axis.get_majorticklabels()\n\
Function Example", fontsize = 12, fontweight ='bold') 
plt.show()

输出:

Matplotlib.axis.axis.get_majorticklabels()

Value of get_majorticklabels() :
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
