问题描述
不幸的是，由于Windows问题，我无法使用LaTeX呈现我的任何matplotlib文本.因此，基本上我已经不需要在matplotlib's文本处理中在字母下方放置一行.
Unfortunately due to a problem with windows I cannot render any of my matplotlib text with LaTeX. So basically I need away already in matplotlib's text handling to place a line underneath a letter.
到目前为止，我最近的是ax.text(x,y,z, r'$\mathbf{\underbar r}$')，但这只会产生_r.因此，如果有一种方法可以使此标杆位于"r"之下，那将是惊人的.预先感谢！
So far the closest I have is ax.text(x,y,z, r'$\mathbf{\underbar r}$'), but this just produces _r. So if there is a way to get this bar under the 'r' that would be amazing. Thanks in advance!
P.S.我已经尝试过ax.text(x,y,z, r'$\underline{\mathbf{r}}$')，但这似乎不起作用，:，(
P.S. I have already tried ax.text(x,y,z, r'$\underline{\mathbf{r}}$') but this doesn't seem to work, :,(
修改
仅意识到您可以通过仅用\underbar将文本放置在完全相同的位置来欺骗" matplotlib:D，从而使它显示在字母下方.即ax.text(x,y,z, r'$\mathbf{r}$')后跟ax.text(x,y,z, r'$\mathbf{\underbar}$')
Just realized that you can 'cheat' matplotlib :D by placing text in the exact same position with just an \underbar, which makes it appear under the letter. i.e. ax.text(x,y,z, r'$\mathbf{r}$') followed by ax.text(x,y,z, r'$\mathbf{\underbar}$')
但是，还是要感谢您指一种快捷的方法！
But a quicker way would still be appreciated, thanks!
推荐答案
您可以在下划线和角色之间使用一些负间距.在这种情况下，\!的三倍效果似乎很好:
You could use some negative spacing between the underbar and your character. In this case it seems that tripling the \! works well:
ax.text(2,7, r'$\mathbf{\underbar \!\!\! r }$')
