I run it twice due to the addition of extra conditions in the second run, I suppose I could create another variable to go in the varlist sequence, but it's probably not worth it and I can at least see what the difference is here, rather than guessing some time later what I have coded up. I used capture noisily because I was finding my analysis was stopping and not graphing (or at least stopping halfway through the run, but I may need to revisit this to see why - I think due to collinearity in the regression but I'll have to take another look.


You can also condition producing the graph on success in the estimation: e.g., 

sysuse auto,clear
forv i=3/6 {
	capt reg price mpg weight turn displacement if rep78==`i'
	if !_rc {
		predict double res`i' if e(sample), res
		scatter res`i' mpg, ti("Graph #`i'") 
	}
}

Although there is no regression #6, it just skips working with the nonexistent results.
