Below examples illustrate the matplotlib.axis.Axis.set_major_locator() function in matplotlib.axis:
Example 1:

Python3




# Implementation of matplotlib function 
from matplotlib.axis import Axis
import numpy as np 
import matplotlib.pyplot as plt 
import matplotlib.dates as mdates 
import matplotlib.cbook as cbook 
    
years = mdates.YearLocator()    
months = mdates.MonthLocator()   
years_fmt = mdates.DateFormatter('% Y'
    
with cbook.get_sample_data('goog.npz') as datafile: 
    data = np.load(datafile)['price_data'].view(np.recarray) 
        
fig, ax = plt.subplots() 
ax.plot('date', 'adj_close', data = data, color ="green"
    
Axis.set_major_locator(ax.xaxis, years) 
ax.set_ylim((100, 300)) 
    
ax.format_xdata = mdates.DateFormatter('% m'
ax.grid(True
   
fig.suptitle("Matplotlib.axis.Axis.set_major_locator()\n\
Function Example", fontsize = 12, fontweight ='bold'
  
plt.show()


Output:
