Oops, I mean 1,2 and 2,3 positions.

Is this the kind of thing you want?

The following should put the legend in the 2,1 and 1,3 positions (the second-to-last command shuts off the plot region of graph b).

gr two scatter mpg mpg price, name(a, replace) legend(off)
gr two scatter mpg mpg price, name(b, replace) yscale(off) xscale(off) leg(, ring(0) pos(0))
gr_edit .plotregion1.draw_view.setstyle, style(no)
graph combine a b a a a b, rows(2)

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.
