用对数刻度设置刻度 [英] set ticks with logarithmic scale

问题描述

set_xticks似乎无法以对数比例工作:

It seems that the set_xticks is not working in log scale:

from matplotlib import pyplot as plt
fig1, ax1 = plt.subplots()
ax1.plot([10, 100, 1000], [1,2,3])
ax1.set_xscale('log')
ax1.set_xticks([20, 200, 500])
plt.show()

有可能吗?

推荐答案

import matplotlib
from matplotlib import pyplot as plt
fig1, ax1 = plt.subplots()
ax1.plot([10, 100, 1000], [1,2,3])
ax1.set_xscale('log')
ax1.set_xticks([20, 200, 500])
ax1.get_xaxis().set_major_formatter(matplotlib.ticker.ScalarFormatter())

或

ax1.get_xaxis().get_major_formatter().labelOnlyBase = False
plt.show()
