In case anybody else is interested in this question, here is an answer
that Stata Tech Support emailed to me today:

There isn't an option in Stata that will allow you to create a "clear"
background for graphs.  However, I have seen users add a picture or scene
as the background with third-party programs such as PhotoShop.

You can try the following instructions in PhotoShop to place a graph
on a picture background:

Open Stata graph in PhotoShop.  Place graph in its own layer (not background).

Select magic wand and in the magic wand options, set tolerance to 0, uncheck
anti-aliasing, check contiguous.

Select background.  If all of background not selected, select Similar from
the Select menu.  Delete selection.

Place background image in layer below Stata graph.


If you're looking to match the background to a specific color, Stata graphs
will take RBG values in addition to the preset colors listed.  For example:

. twoway (scatter x4 x3), graphregion(fcolor(212 55 155))

Hope this helps.

It's possible that the transparent feature could be made available in a
future release, but there hasn't been anything mentioned specifically for
an update, etc.
