To follow up my previous posting, you
can do this with less typing (and without changing
your existing variables)
sysuse auto,clear
reg price mpg fore
predict fit
separate fit, by(foreign) veryshortlabel
twoway line fit? mpg, clcolor(blue green)
ytitle(Predicted Price)
The -veryshortlabel- option is undocumented,
but helpful here.
