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.

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?

The basic idea is that the axis line is drawn only for the range of the data. I've managed to create it (for the yaxis only in this example) as follows: . sysuse auto . graph twoway scatter mpg price  /// scatteri 12 250 41 250, c(l) msym(none) , /// plotregion(margin(l 0 b 0)) yscale(noline) /// ylab(12 41, nogrid) xscale(ra(200 15000)) /// legend(off) yscal(ra(10 45)) But this seems like a pretty ugly way to go (and requires some adhoc tinkering). I'd have thought that the yscale(noextend) option would get me where I want to go, but this command: . graph twoway scatter mpg price , yscale(noextend) draws a yaxis that runs from about 15.5 to 26.2. Not sure why that's happening. Is this something someone has programmed, or on which someone has a better approach?
