label on plot

[<Nigel.Yateman@sanofi-aventis.com>]

Dear All
I would like to add a label "³65" on a plot (i.e., a greater than or equal sign, where ">" and "=" are given in one single character).

I already have a label "m²", and for this I used "m\262" in the text() function.

Is there an equivalent code for "greater than or equal to", and in general how do I find out what other codes exist.

Thanks a lot in advance,
Nigel
