删除matplotlib中的乳胶下标中的斜体 [英] remove italics in latex subscript in matplotlib

问题描述

我想删除在标签中使用下标时出现的斜体字体.例如，x标签中的"Teff"用斜体字表示"eff".我希望乳胶不要以这种方式呈现.通常，在乳胶中，可以使用\ rm {}命令来实现.但是，这在matplotlib中不起作用.请帮忙.

I would like to remove the italics font that appears when I use subscripts in labels. For example, the "Teff" in the x-label has "eff" in italics. I would like latex not render it in such a way. Generally, in latex this can be achieved with the \rm{} command. However, that does not work in matplotlib. Please help.

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(10)
y = x

plt.plot(x,y,'ro')
plt.xlabel('Primary T$_{eff}$')

推荐答案

我已经多次遇到此问题，可以通过此技巧解决

I have encountered this problem many times and it can be solved with this trick

plt.xlabel(r'Primary T$_{\rm eff}$')
