```You could do something like this:

sysuse auto, clear
regr mpg weight i.foreign
predict predict
separate predict, by(foreign) veryshortlabel
line predict? weight, sort

If you want the fits to be different, you are going to have to produce them separately and then combine them, I believe.

drop predict?

forval i = 0/1 {
qui regress mpg weight if foreign == `i'
predict predict`i' if foreign == `i'
label var predict`i' "`: label (foreign) `i''"
}

line predict? weight, sort ytitle("`: var label mpg'")

Many thanks, it looks great.
Could I somehow use -lfit- to get the fitted lines only?

From: Nick Cox <n.j.cox@durham.ac.uk>

Try

separate moment, by(brackettype) veryshortlabel
line moment? rotation

and see -help separate-

In Stata 12, I am using the following commands:

twoway (line moment rotation, by(brackettype)) // moment and rotation continuous and brackettype has 4 levels

I like to have all graphs in one plot as shown below but somehow I cannot get on the legend below the x-axis to show the levels of brackettype. It shows "brackettype" for all 4 different color lines. If I use "lfit" instead of "line" it shows lfit instead of brackettype.

twoway (line moment rotation if brackettype==1) ||(line moment rotation if brackettype==2) ||(line moment rotation if brackettype==3) ||(line moment rotation if brackettype==4)
