Apologies for not getting back to you earlier.
The pan & zoom support was mainly designed as part of the Stock Chart. We still have a few kinks to iron out to make it truly usable on its own. Hence the missing demos in the official release.
I've prepared a quick demo of a custom pan & zoom implementation over here: http://jsbin.com/ulapis/1
There is a problem with the ranges for vertical axes (they're reported in reverse), but we're working on a fix.
