[PD] graph-on-parent feature - how to use?

i have some questions concerning the graph on parent feature.

first of all: does it work only on a subpatch? (namely: can i have graph for an abstraction)?

then, i tried to create a subpatch, inserted a lot of radio and toggles (my purpose is to make a sequencer... for now i'm creating the data matrix), but when i activate the graph-on-parent, my subpatch (seen from the parent) doesn't looks like the original. please jump here to see: http://xaero.ath.cx:2005/8674/ (if you can't view it: the controls on graph appear at wrong position. i have to resize the subpatch at least twice its size, leaving a lot of blank space around the graph(controls))

i tried playng with these parameters:

• [subpatch canvas] -> X/Y units per pixels (it doesn't change at all),
• [subpatch] screen width/height (it resizes, but also move controls at

wrong positions)

what i have to do to make an UI appear as i see it in the corrispective (sub)patch?

thanks
