st: subscript in legend labels

[Katja Recknagel <recknagel@phil-fak.uni-duesseldorf.de>]

Hello!

Is it possible to use the subscript-option to label legends? I have 
tried and got a superscript instead of a subscript. What have I done 
wrong? I´m using Stata 11 by the way.
The code of my graph:
graph twoway (function y=exp(2+x)/(1+exp(2+x)), range(-10 10) 
lcolor(black) lpattern(solid)) (function y=exp(x)/(1+exp(x)), range(-10 
10) lcolor(black) lpattern(dash)), legend(label(1 "ß {sub:0} = 2") 
label(2 "ß {sub:0} = 0"))
Thanks a lot!
