I think the short answer to Paul is that there is no easy way that he can use to translate automatically to the -graph- syntax he knows. 

Developing this a bit and interpolating between various Stata developer comments: 

Paul is seeing low-level language that is intended primarily for Stata's internal consumption. 

Since Stata 8 came out I know of precisely one person outside StataCorp who has had the perseverance and ingenuity to work up a good understanding of this low-level language, Sergiy Radyakin. 

I am a fairly dedicated user of Stata's graphics and have written several programs on top of it, but whenever I've felt I needed to know some of this low-level language perseverance of a different kind has typically shown a way round. 

There was for a while an intention that StataCorp would document this language, but it was quickly realised that that would mean writing, in effect, an extra volume of the manual for about three people. Those three people (plus or minus a few, perhaps) may feel cheated, but the rest of the user community benefits from whatever the developers did with the time freed. 

So, Paul, you would need a manual volume to help you do this, but it does not exist. If it did exist, you would still need to exert considerable programming skills.

the best description of this was sent to me by Luis Armando Galvis off list (thanks). he pointed me to this page: http://www.survey-design.com.au/tips.html

as it is buried in the page i have copied it here:

> Getting Stata's Graph editor commands into Stata graphs
> Stata has a great graph editor. However, after you have modified your graph the editor will not produce the normal Stata code for this graph. However, it is possible to retrieve the editing commands if they have been recorded using the Stata graph editor recorder, adding gr_edit at the start of each editor line and then adding this to the initial graph code. Now you have the code to reproduce the graph.

==================

now, the question is how to translate this line:

gr_edit plotregion1.plot1.style.editstyle area(shadestyle(color(gs7))) editcopy

into a command. 

this is a very simple one, changing colour. are there general rules?
