st: growth curve graph

["Sharma, Ramesh R" <Ramesh.Sharma@uky.edu>]

I'm trying to graph a linear growth curve equation (based on xtmixed,
with varying intercepts and slopes). The dependent variable is
continuous. The time variable at level 1 is time (0-300) in days (in
three survey waves, but with different survey dates and different
lengths of time between survey occasions for different respondents).
The variable of interest at level 2 is a dichotomous variable. Is
there a straightforward way to obtain a graph (time in days on the x
axis and the dependent variable on the y axis, showing two straight
lines, sorted by the dichotomous level-2 variable) showing the
estimated population average trajectories (and not the estimated
trajectories for all respondents, sorted by the level 2 variable,
displayed in one graph)?

Thanks,
Ramesh
