Matplotlib中使用乳胶的Sans-Serif数学 [英] Sans-serif math with latex in matplotlib

问题描述

以下脚本:

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as mpl

mpl.rc('font', family='sans-serif')
mpl.rc('text', usetex=True)

fig = mpl.figure()
ax = fig.add_subplot(1,1,1)
ax.text(0.2,0.5,r"Math font: $451^\circ$")
ax.text(0.2,0.7,r"Normal font (except for degree symbol): 451$^\circ$")

fig.savefig('test.png')

尝试在matplotlib和LaTeX中使用sans-serif字体.问题在于数学字体仍然是衬线字体(如轴号所示，以及中心的标签所示).有没有办法将数学字体也设置为sans-serif?

is an attempt to use a sans-serif font in matplotlib with LaTeX. The issue is that the math font is still a serif font (as indicated by the axis numbers, and as demonstrated by the labels in the center). Is there a way to set the math font to also be sans-serif?

推荐答案

我的matplotlibrc文件中总是有text.usetex = True.除此之外，我也使用它:

I always have text.usetex = True in my matplotlibrc file. In addition to that, I use this as well:

mpl.rcParams['text.latex.preamble'] = [
       r'\usepackage{siunitx}',   # i need upright \micro symbols, but you need...
       r'\sisetup{detect-all}',   # ...this to force siunitx to actually use your fonts
       r'\usepackage{helvet}',    # set the normal font here
       r'\usepackage{sansmath}',  # load up the sansmath so that math -> helvet
       r'\sansmath'               # <- tricky! -- gotta actually tell tex to use!
]
