In the same spirit, and standing on Vince's shoulders (*),
------------------------------- myhistogram.do
qui su `0'
local imin = ceil((r(min) - r(mean))/r(sd))
local imax = floor((r(max) - r(mean))/r(sd))
forval i = `imin'/`imax' {
local labels `"`labels' `= r(mean) + (`i') * r(sd)' "`i'" "'
}
set graphics off
histogram `0', t1(z scale)
.Graph.insert (.xaxis2 = .axis.new , position(above)) above plotregion1
.Graph.set_axis_plotregion xaxis2 plotregion1 x
.Graph.xaxis2.major.add_ticks `labels'
set graphics on
graph display
-----------------------------------
This should work as follows:
do myhistogram systolic
do myhistogram systolic if female
etc.

"at whose feet we sit, on whose shoulders we stand". Only topologists could
visualise the resulting position.
