Thank you Nick.
Your suggestion
foreach ID of local IDS {
su BMI if id == `ID', meanonly
line hem time, t1title(`r(min)')
}
seems the only one which allows to display a changing value for each subject.

Objet : st: RE: RE: Add variable value on a graph
The persuasion Martin suggests is unnecessary. You can add text to a
-line- graph using
-text()-. Or you can put the same text in a title or the legend.
Here is a dopey example.
. sysuse auto
. sort weight mpg
. line weight mpg, text(3000 25 "some text")
If Alvine's problem were mine, I'd probably use -t1title()-. This is best
done as a loop, e.g.
levelsof id, local(IDS)
foreach ID of local IDS {
su BMI if id == `ID', meanonly
line hem time, t1title(`r(min)')
}

If you could be persuaded to use a -scatter- instead of -line-, then -help
scatter##marker_options- shows that you can add the value of a variable of
your choice to the marker symbols...

I would like to create a graph with repeated values of hemoglobin versus
time (0,1,2,6 and 12 months) for each subject of my data .
gr twoway (line hem time) if id==1
I have a variable "BMI" in my data base which gives the BMI of each subject.
I would like to add the value of BMI on each graph for each subject (as
legend) .
Is it possible to add on a plot the value of a variable ?
