Nothing prevents you from using your -egen-erated variables, btw:
*************
sysuse auto, clear
egen maxprice=max(price)
egen minprice=min(price)
egen meanprice=mean(price)
scatter weight price, ///
xline(`=minprice' `=meanprice' `=maxprice') ///
xla(`=minprice' `=meanprice' `=maxprice')
*************
As you rightly say, these are constant. Stata just grabs the first
observation and processes it, if you refer to it via `= '...

Betreff: st: finding the max of a variable and then using it
Hi,
I have a data set with a variable called opp_price. I'd like to find
the maximum value for opp_price (I would imagine I'd use
egen opp = max(opp_price)
or something like this, but then use this single value in subsequent
graphing statements like the following:
xline(opp, lwidth(thin))
text(0.0 238 "OPP: $opp", place(w))
Of course this doesn't work since opp is a new variable with as many
observations as opp_price. I need a scalar that I can then use in
subsequent statements. Can anyone help?
Thanks,
Walt
