" Why are there no -(lfit y x)- and -(lfitci y x)- options with -graph
matrix?"
I would not call these options. The -twoway- family allows you to add
additional types of -graph-s to an existing one. -gr matrix- is not part of
this family, so systematically I would not expect there to be an -add plots-
capability. -hist-, for instance, does allow that, so in future what you
call for may be desirable. I do note though that -gr matrix- already takes a
long time to draw its plot so allowing additional plots would certainly make
that worse...

I've been playing around with Nick's solution with some of my own
data, and it turns out to be quite useful, especially when I switch on
the -if e(sample)- option.
One question for StataCorp: Why are there no -(lfit y x)- and -(lfitci
y x)- options with -graph matrix? If I'm not missing anything obvious,
this would make -graph matrix- even more useful than it already is.
