Dear Aga,

If you had Stata8 you could have used my earlier post:

-twoway function y = exp(-_b[mpg]*x- _b[mpg2]*x^2), range(12 41) 
ytitle("odds") xtitle("mpg")- gives you the odds of belonging to a
group versus all `lower' groups.

now you could do something like: 

version 7
sysuse auto
gen mpg2 = mpg^2
ologit rep78 mpg mpg2

preserve

drop _all
set obs 31         
gen mpg =11 + _n
gen odds = exp(_b[mpg]*mpg + _b[mpg2]*mpg^2)

graph odds mpg, c(l) 

restore


I forgot the correct -graph- syntax for stata7 to make the pretty, but
this should get you started.
