I should have mentioned one more thing: I use an older version of
Stata (Stata 8), but when I was researching commands, some
instructions mentioned "addplot" instead of just plot, but this did
not work for me.  Possibly this is the command you would want to use
for more recent versions of Stata, but I am not sure.
