X bar symbol

[one09jason]

Does anyone know how to produce an x bar symbol in Mellel? You know, the symbol for the statistical mean - a lower case x (greek letter chi actually) with an overline or macron over it. I can't figure it out, even witth the character palette. Please help.

In the new Mellel 2.2, you can put an overline over any letter. Open the Character Appearance palette, click on the giant letter, click on the button labeled "Line" directly under the giant letter, and select "overline", then type your greek letter. It will have the overline above it.

It looks like the x-bar symbol isn't a separate symbol in the unicode standard and therefore you couldn’t find it in the character palette. It’s a symbol that is generated by equation editors of the two components “x” and the bar “—”.
To insert such a character into Mellel, you could either use the new (as of version 2.2) overline feature (insert the character x and then add a overline instead of a underline via the Character Appearance palette) or you could use a external equation editor to generate the character.
With the freely available LaTeXiT*, the symbol is generated by inserting the code “\bar x” into the LaTeXiT code window.

LaTeXiT requires a LaTeX base installation which could be downloaded via the so called i-installer from this website: http://ii2.sourceforge.net/tex-index.html

The standard way to do macron x would be with the US Extended layout, typing x then Option + Shift a. However it may only look right with some fonts, like Lucida Grande. You can also try it with chi. For an overline you can input U+0305 from the Character Palette after x or chi.
