We're almost there. I tried this, and got the following

. gs_fileinfo  "/Users/ronanconroy/Documents/Consult files/Richard
Costello/FVC50.gph"

. di r(command)
twoway  (line  __00000H __00000I _t, sort connect(J ...) ylabel(0(.25)1,
grid) ytitle(`""')  x

There is an obvious problem: the graph (A Kaplan-Meier) is described in
terms of the variables that Stata calculated, and the underlying command
(-twoway-) not the original command syntax that I used (-sts graph-).


However, the other information returned is very useful indeed. So much so
that I am surprised that Stata doesn't have a menu item saying 'get graph
info' rather than an undocumented command!

With a little modification, however, it is clear that Stata could capture,
verbatim, the command used to generate a graph. What it captures right now
is maddeningly close...
