I need to be able to graph the baseline and treatment as a single graph with a vertical line separating the two phases. In each phase I need to have a line connecting each data point (but not from phase 1 to phase 2). I also need the ability to add a regression line to each phase - each phase gets its own line, independent of the other phase regression line. I've looked through Mitchell's "A Visual Guide to Stata Graphics" 3rd Ed., but there isn't an example like this and so far I haven't found anything like this in the archives. My efforts to use twoway have so far failed to produce anything close. Using twoway with xrescale and a by statement gives me two separate graphs and I really want to do this in a single graph. Ideas?
