Given rectangles with text:

\starttext Before:\\ \startMPcode draw unitsquare xscaled 2cm yscaled 1cm; \stopMPcode \\ After:\\ \startMPcode for i=0 upto 1: draw unitsquare scaled 1cm xshifted i*cm; endfor; \stopMPcode \stoptext

How can a line be drawn connecting the right edges of the rectangles? I have played with:

\startuniqueMPgraphic{line} path a; a:=(0,0)--(0,3cm); draw a withpen pencircle scaled 3pt withcolor green; \stopuniqueMPgraphic

\defineoverlay[line][{\uniqueMPgraphic{line}}]

and using it in \framed, but placing the line correctly is elusive.

Look at chapter 5 in the metafun manual. Wolfgang
