How do these graphs come into being? In your example, you reuse the "a"
graph three times, but in reality I bet you have different ones. Note that
with the -by- option, you do get a nice placement for the -legend-:


*************
sysuse auto, clear
tw (scatter mpg price), by(, legend(on position(0) at(6))) by(rep78)
*************

Hi,

I'm trying to automate a modification to -grc1leg-, to move the single 
legend into a "hole" in the combined plot.  There are two ways I can get 
what I want:


sysuse auto, clear
gr two scatter mpg mpg price, name(a, replace) legend(col(1))

* Way One
grc1leg a a a , ring(0) pos(4) name(drag)
gr_edit .legend.DragBy 21 -15

* Way Two
grc1leg a a a , ring(0) pos(4) name(setmargin)
gr_edit .legend.style.editstyle boxmargin(0 15 20 0) editcopy


So my question is whether anyone can give me advice on automating 
figuring out the amount to drag (method 1) or the size of margins needed 
(method 2) to put the legend in the middle of an arbitrarily specified 
hole in the grid of plots?

Ideally I'd like to be able to do something like:

   grc1leg a a a a a, hole(5) putlegend(5)

Which I can achieve by trial and error with

   grc1leg a a a a a, hole(5) ring(0)
   gr_edit .legend.DragBy 21 0


which moves the legend to the middle of the hole created by the hole() 
option.  But to do that I need to figure out the size of the legend, and 
the size of the hole, I'd guess.

Thanks for any thoughts.
