-qfitci- and -lfitci- are just bivariate regressions displayed
as graphs, so they won't capture any interactions. If you are
thinking about doing this for a number of variables then you
are probably better of using -graph matrix-, see : 
-help graph matrix-. This displays the actual bivariate 
relationships rather than imposing some model on it. If you
are interested in displaying interactions, than you will need
to tell us more about your model.

Hope this helps,
Maarten
