OK, I have added the plus-minus symbol, designated as
"+-" in cgSymbol. But the minus-plus symbol does not
exist in the Symbol true-type font distributed with
IDL. Thus, I can only do this symbol in a Hershey font,
but not in a PostScript font. So, I have not implemented
the minus-plus symbol.

The updated program is here:

Cheers,

David

I assume he was looking for the "plus/minus" symbol, not the "plus" and
"minus" symbols :-)

That one would be at octal 261 in the symbol font table on the greek
symbol page that you referenced earlier.

Oh, sorry for the confusion. The symbol after values and before 1-sigma uncertainties. \pm in tex. And inversely, also the "-/+" symbol.

I've just always used "+" and "-" from the normal
font. A Hershey font on the display and a hardware or
true-type font in PostScript. Do you mean some kind
of special plus and minus!? I'm not really sure what
you are looking for here.

Cheers,

David

Thanks again David. I didn't see a plus-minus symbol in there. Is there an easy way of getting one that postscript will like without using octal tables?

Humm. I wonder where that page went. I'll look into this. :-(

You can display all the symbols in cgSymbol by doing this:

IDL> void = cgSymbol(/Example)

Or, you can create a PostScript example page like this:

IDL> PS_Start
IDL> void = cgSymbol(/Example)
IDL> PS_End

The old Greek page also has a list of the symbols:

http://www.idlcoyote.com/ps_tips/greeksym.html

The additional cgSymbol symbols are at the end of the page.

Cheers,

David

Ha! Never mind, chalk that dumb question up to lack of caffeine. Of course, I could just *scroll down* in the code. Facepalm.

David,

Thanks so much for the quick reply. I'm trying to get a full symbol list for cgsymbol, and the docs point me to:

http://www.idlcoyote.com/cg_tips/cgsymbol.html

which doesn't appear to be alive anymore. Is there a reference online for all symbols, including non-greek symbols?

Yes, see the end of this article:

http://www.idlcoyote.com/cg_tips/kwexpressions.php

This can be made slightly easier by using cgSymbol instead of
TexToIDL, if you can, since cgSymbol can return the PostScript
value by simply setting the PS keyword.

Cheers,
