matplotlib子图的刻度标签字体不一致 [英] Inconsistent tick labels font with matplotlib subplots

问题描述

我正在使用 matplotlib.pyplot.subplots 绘制图表网格，我希望刻度标签使用LaTeX的sans-serif字体，但是当我使用subplots时，我总能得到至少一个刻度标签以 matplotlib 的默认字体呈现.

I'm making a grid of plots using matplotlib.pyplot.subplots, and I want the tick labels to be in LaTeX's sans-serif font, but when I do use subplots I always get at least one tick label rendered in matplotlib's default font.

这是MWE:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=1, ncols=1)
x = [1,2,3,4,5]
plt.plot(x)
plt.rc('text', usetex=True)
plt.rc('font', family='sans-serif')
plt.show()

如果您注释掉 fig, axes = plt.subplots 行，刻度标签会按原样显示.

If you comment out the fig, axes = plt.subplots line, the tick labels display as they should.

我正在使用python 3.6.0版和matplotlib 2.0.0版

I'm using python version 3.6.0 and matplotlib version 2.0.0

推荐答案

对 rcParams 的更改应始终尽快进行，并且必须在创建它们影响的对象之前进行.

Changes to the rcParams should always be made as soon as possible and necessarily before the objects they affect are created.

因此，将rc更改放在最前面，可以解决此问题:

Thus, putting the rc changes at the top, resolves the issue:

import matplotlib.pyplot as plt
plt.rc('text', usetex=True)
plt.rc('font', family='sans-serif')

fig, axes = plt.subplots(nrows=1, ncols=1)
x = [1,2,3,4,5]
plt.plot(x)

plt.show()
