将换行符与Python中的TeX一起放在matplotlib标签中? [英] Putting newline in matplotlib label with TeX in Python?

问题描述

如何在matplotlib中向图的标签(例如xlabel或ylabel)添加换行符?例如，

How can I add a newline to a plot's label (e.g. xlabel or ylabel) in matplotlib? For example,

plt.bar([1, 2], [4, 5])
plt.xlabel("My x label")
plt.ylabel(r"My long label with $\Sigma_{C}$ math \n continues here") 

理想情况下，我也希望y标签也居中.有没有办法做到这一点?标签必须同时包含TeX(用'$'括起来)和换行符.

Ideally I'd like the y-labeled to be centered too. Is there a way to do this? It's important that the label have both TeX (enclosed in '$') and the newline.

推荐答案

您的示例正是使用\n的示例.您需要删除r前缀，以便python不会将其视为原始字符串

Your example is exactly how it's done, you use \n. You need to take off the r prefix though so python doesn't treat it as a raw string
