修改python plot折线图的坐标轴刻度方法

from matplotlib import pyplot as plt
import matplotlib.ticker as ticker
import numpy as np

 plt.figure()
 plt.plot(overall_std, label='average_std')

 plt.plot(max_std, label='max_std')
 plt.legend()
 plt.xlabel('window')
 plt.ylabel('std')
 plt.xticks(range(len(max_std)))
 # plt.gca().xaxis.set_major_formatter(ticker.FormatStrFormatter('%1.1f'))

 plt.show()
