twoway, label | tick properties

[Chiara Tasselli]

Good morning,
I a trying to run the following command for seeing the trend in multiple sub-samples:

twoway   (lfit WORK_avarage Time if TREAT == 0 & FEMALE == 1)(lfit WORK_avarage Time if TREAT == 1 & FEMALE == 1) (lfit WORK_avarage Time if TREAT == 0 & FEMALE == 0)(lfit WORK_avarage Time if TREAT == 1 & FEMALE == 0), by(school)

The command work, but once run it I cannot distinguish to which sub-sample each line belongs because they are all labelled 'fitted value'. There is an option that I can enter to have a distinction ? (like i was thinking to give a title|label in each intra-parenthesis line... is it possible?

Many thanks in advance for your time

Consider this similar problem (in the absence of a data example)

sysuse auto, clear

twoway lfit mpg weight if rep78 <= 3 || lfit mpg weight if rep78 >3 , by(foreign) legend(order(1 "Record <= 3" 2 "Record 3 or 4"))
