In OO Calc how do you insert a x-bar symbol (an x with a bar on top of it)?

Can't find this in my fonts (Insert>Special Character) but I did not search too long.
You can insert a formula-object.
Insert>Object>Formula...
Button "Attributes" provides: overline <?>
Replace <?> with x

That gives you a picture. I need x-bar in text. I looked for 10 minutes in the special character lookup. Mad

I've had a quick look in google and alltheweb. From what I can see the options are:
  • Use a graphic
  • Use a suitable equation/math editor (ie. insert an OOo Formula object)
  • Write up your doc in such a way as to avoid the use of the x-bar symbol
What I have done in spreadsheets in the past is just type "X-bar" (and if you're setting up control charts, I have used R-bar, UCLx, LCLx, UCLr....) - - not as pretty, but it gets the message across.

Another day and another incomprehensible concept.

Try an image search. I found a lower case and an upper case symbol on < this page >.

According to Wikipedia:
Quote:
The term X-bar is derived from the notation representing this new structure. Certain structures are represented by X (an X with an overbar). Because this is difficult to typeset, this is often written as X′, using the prime symbol. In English, however, this is still read as "X bar". The notation XP stands for X Phrase, and is equivalent to X-bar-bar (X with a double overbar), written X″, usually read aloud as X double bar.


Sun has one.

Yeah, I found that when I went looking for a suitable font (character set). However, given that we're in the
Calc forum (hence arithmetic and other number-crunching) I had assumed x-bar to refer to the Arithmetic Mean

Obviously, you are correct. So, there are two of these things? How's a person supposed to keep up?

IIRC Latex would do this quite easily.

Use the math editor.... bar x
You might want to size the result larger.

IMO, this is easier do now with the overline feature in OpenOffice.org 3.1. It's near the emboss setting in the Format menu under Characters.

(I know it's an old post, but people do search the archives.)

AndrewZ, that is definitely the best answer to this solution. Thank you so very much! I didn't even realize that feature was in the software until I read your comments.

Thank you! This is so easy. You're right, too: we DO search archives.
