Thanks, James, but what you're suggesting oversimplifies the problem and eliminates part of the dataset I want to include. Eric properly expresses it-- I have a dataset for which a < b < c < d of my x-axis variable. I want to estimate and fit a line over [a, d], but only want the graph to display [b, c]. This is the base command I'm working with, if that tells you anything: twoway (scatter var1 var2 if year >= 1990 & year <= 2004 & usegr2==1, msymbol(smcircle)) (lfit var1 var2 if year >= 1990 & year <= 2004) if usegr==1, yscale(range(0 40)) xscale(range(0 10)) Is this possible?

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?
