matplotlib横轴密度修改

import numpy as npimport matplotlib.pyplot as pltx = [0,5,9,10,15]y = [0,1,2,3,4]plt.plot(x,y)plt.xticks(np.arange(min(x), max(x)+1, 1.0))plt.show()

import matplotlib.pyplot as pltimport matplotlib.ticker as tickerx = [0,5,9,10,15]y = [0,1,2,3,4]tick_spacing = 1tick_spacing = 5#通过修改tick_spacing的值可以修改x轴的密度#1的时候1到16，5的时候只显示几个fig, ax = plt.subplots(1,1)ax.plot(x,y)ax.xaxis.set_major_locator(ticker.MultipleLocator(tick_spacing))plt.show()
