A nice cross between my proposal and Scott's is
twoway scatter mpg price, ylabel(minmax,nogrid) ///
xlabel(minmax) yscale(nofextend) xscale(nofextend) plotregion(lcol(none))
This is clean and simple but gives the default gap.

Subject: Re: st: RE: Graph axis labelling range
Yes, that gives a version of what I'm looking for. I also want to be
able to extend the range of the axis, yet also retain the ability to
have the axis line only extend over a defined range. For that, I think
I need an approach along the lines of what I was doing, as made more
elegant by Thomas Steichen.
(That is, doing something like yscale(ra(0 50)) then means that the
nofextend draws the axis from 0 to 50.)
A question for Statacorp, perhaps: is there a way to extract
programmatically the size of the default gap between the axis and the
data area, from the current scheme?
