x bar, symbol for average width for labeling
I was wondering if it is possible to display the character x bar. I want to use it in the context of auto labeling the average width of streams/canals so it has to be able to be entered into the tabular record of a feature.
Mapping Center Answer:
You can use a formatted text tag to do this. You also have to find the symbol you want to use. I found it in the MS Reference Sans Serif font. Here is how you can look for it on your computer:
- Click Start, then All Programs, then Accessories, then System Tools, then Character Map. Set the font to be the MS Reference Sans Serif font.
- Find the symbol for the x bar symbol (it is likely U+F7C2, U+F7C3 or U+F7C4 - look in the lower right corner of the dialog box to see this Unicode value).
Now you can use this in a formatted text tag. Say, for example, that you want to use thsi label: x bar = [the average value]". You label expression would be:
"<FNT name='MS Reference Sans Serif'>" & " ? " & "</FNT>" & " = " & [this_is_your_attribute_value]
To get the "?" into this expression, in the Character Map window, click on the x bar symbol, then click Select at the bottom. Once it shows up in the "Characters to copy" area, click "Copy". In ArcMap, in the label expression dialog box, copy that character into the expression.
