Text Formatting ⇒ The greek letter chi

[Bleevoe]

I'm trying to make a chi (the greek letter) that looks like this:

I've managed to find three different chis: \chi, \chiup and \upchi, but none of them look like the one above. This is the result I get using those three:

My biggest qualm with these three is that they are all kind of lowered compared to the x and \in symbol.

I realize that the chi in the first picture might be custom-made, but here's to hoping it isn't and that someone knows about it.

Use the \raisebox command to raise the chi. If I do this in math mode:

Code: Select all

x \in \raisebox{2pt}{$\chi$}

I get this:

Ah, it's still not the same as the one in the first picture, but I suppose it's good enough for me. Thank you.

The "chi" in your first picture is a simple capital »X« in math mode.

Sorry about the previous external links.

My capital X (or capital chi, which apparently is the same) doesn't look like that.

Code: Select all

\documentclass[a4paper,12pt]{article}
\begin{document}
    \[x \in X\]
\end{document}

gives me

I missed a small detail in my last post. Originally I wanted to write that it is a capital calligraphic »X«. Sorry for the confusion. Sometimes one word can make a big difference.

Code: Select all

\documentclass[12pt,a4paper]{article}

\begin{document}
  \[
    x\in\mathcal{X}
  \]
\end{document}

Ah, there it is! Thank you.

Be careful with \raisebox since is a fragile command. With the current definition for "chi" you can have problems when trying to use it, for instance, in a caption. You will have to used the command \protect each time, or introduce it in the definition of chi

Code: Select all

\newcommand{\goodchi}{\protect\raisebox{2pt}{$\chi$}}

Additionally, it good be also good to have a more generic measure instead of 2pt. For instance a length that is a fraction of the actual length of the letter chi. This way, the definition will be still valid even when changing the font size.
