This can be easily overcome with the overline option.

overline: \overline

usage: \overline{test}

Explanation: The overline option should be used instead of bar option.

The following code demonstrates the difference

\documentclass[12pt]{beamer}

\mode

\usetheme{Boadilla}

}

\begin{document}

\begin{frame}[plain]

\begin{alertblock}{WRONG}

\begin{align*}

Z& = \frac{\bar{BMI}-\mu}{\sqrt{\frac{\sigma^2}{N}}} \\

& = \frac{\bar{BMI}-\mu}{SE(\bar{BMI})} \\

\end{align*}

\end{alertblock}

\begin{exampleblock}{RIGHT}

\begin{align*}

& = \frac{\overline{BMI}-\mu}{SE(\overline{BMI})} \\

\end{align*}

\end{exampleblock}

\end{frame}

\end{document}

Which produces the following slide

Thanks, this was exactly what I was looking for. Keep it up!

ReplyDeleteIt helps a lot...

ReplyDeleteThanks so much. I really needed this for my thesis.

ReplyDeleteThanks! Just what the doctor ordered.

ReplyDeleteMany Thanks!

ReplyDeleteThank you!! My thesis was looking weird until I found this.

ReplyDeleteThank you, though if you have an index to the letter than the overline, there is a white space between the letter and its index and it looks horrible.

ReplyDelete\documentclass[12pt]{beamer}

\begin{document}

$\overline{V}_\textrm{p}$ instead of $\bar{V}_\textrm{p}$

\end{document}

Does anyone knows how to avoid the space between the V and p?

Thanks

You can put whatever you want in the argument to the overline command, so to put the overline above a number and its subscript, you do:

ReplyDelete$\overline{V_\textrm{p}}$

You can also eliminate the space without having the overline cover both the symbol and its subscript by inserting a negative space (\!) between them:

ReplyDelete$\overline{V}\!_\textrm{p}$

Thank you Kbolino, that's exactly what I was looking for.

DeleteThank you!

ReplyDeleteThat made my notes look nicer, and also lead me to try underline, which is what I wanted elsewhere. Thanks!

ReplyDeleteThanks, nice tip!

ReplyDeleteTHANK YOU! :)

ReplyDeleteThank you for helping me write my paper!

ReplyDeleteThanks! It saved the beauty of my thesis!

ReplyDeleteVery helpful, thanks!

ReplyDeleteI would say this is correct if you have a variable with several letters (eg. BMI in the example). But if you have a variable with a single letter (eg. x), then \bar is better than \overline.

ReplyDeleteThank you!

ReplyDeleteThanks man, thesis on course too

ReplyDeleteThanks, this helped fix my thesis!

ReplyDeleteSometimes the overline is too wide. Is there a command in-between \bar and \overline?

ReplyDeleteYes, but you have to define it yourself.
