John,

I'd use a grads script to return the XY coordinates of the sides of the
plot using "q gxinfo", then use "draw string" to plot labels relative to
the 4 corners.  Include something like this to  get the X and Y values
of the sides of the plots:

'q gxinfo'
xvalues=sublin(result,3)
yvalues=sublin(result,4)
* xl = plot starts xl inches from left
* xr = plot ends xr inches from left
* yb = plot starts yb inches from bottom
* yt = plot ends yt inches from bottom
xl=subwrd(xvalues,4)
xr=subwrd(xvalues,6)
yb=subwrd(yvalues,4)
yt=subwrd(yvalues,6)


The lower left corner of the plot would be at "xl" "yb". Upper left at
"xl" "yt". Upper right "xr" "yt". Lower right "xr" "yb".
