I don't think this is what Amanda wanted. The way I understand her, she wishes to estimate and fit a line over the range (a b) but only show the graph for that fit over the range (c d) where a < c and d < b

Hello,
I haven't seen a response to this yet, so I'll take a stab at it.
I'll have to make some assumptions, since you haven't explicitly said which command you are using.
I assume you're using -twoway lfit-.
Here's another option, which forgoes the convenience of -twoway lfit- but gives extra control:
regress y x
predict yhat
twoway (scatter y x if x >= 1 & x <= 10) (line yhat x if x >= 1 & x <= 10, sort(x))

Subject: st: Graph: Control plot region- contract, not expand
Hello all,
I'm trying to create a fairly simple graph- just a scatterplot overlayed with a linear prediction. My problem is that I can't seem to control which area of the graph to display. I know I can expand the plot region, but there doesn't seem to be a similar code to force-contract it.
All I care about is the 1-10 region on my scale (x-axis), where some outliers are outside of this region. Of course, if I drop these outliers, the graph region cooperates. Is it possible to crop the display region without dropping the observations which determine the behavior of the linear prediction? Like a way to force the command
"xscale(range(0 10)"?
Ideally, I'd like to compare 2 graphs-- one with the outliers, and one without, but only along the smaller region of the x-axis.
Many thanks-
Amanda
