python matplot 画网格坐标轴方法

Displaying a grid on the axes in matploblib.

import matplotlib.pyplot as plt

ax = plt.axes([0.025, 0.025, 0.95, 0.95]) #[xmin,ymin,xmax,ymax]

ax.set_xlim(0,4)
ax.set_ylim(0,3)
ax.xaxis.set_major_locator(plt.MultipleLocator(1.0))#设置x主坐标间隔 1
ax.xaxis.set_minor_locator(plt.MultipleLocator(0.1))#设置x从坐标间隔 0.1
ax.yaxis.set_major_locator(plt.MultipleLocator(1.0))#设置y主坐标间隔 1
ax.yaxis.set_minor_locator(plt.MultipleLocator(0.1))#设置y从坐标间隔 0.1
ax.grid(which='major', axis='x', linewidth=0.75, linestyle='-', color='0.75')#由每个x主坐标出发对x主坐标画垂直于x轴的线段
ax.grid(which='minor', axis='x', linewidth=0.25, linestyle='-', color='0.75')#由每个x主坐标出发对x主坐标画垂直于x轴的线段
ax.grid(which='major', axis='y', linewidth=0.75, linestyle='-', color='0.75')
ax.grid(which='minor', axis='y', linewidth=0.25, linestyle='-', color='0.75')
ax.set_xticklabels([])#标记x轴主坐标的值,在这里设为空值，则表示坐标无数值标定；其他情况如

#ax.set_xticklabels([i for i in range(10)])

ax . set_yticklabels ([]) plt.show ()
