Perhaps you can react to a selection event in the first chart by initiating a selection event on the second chart (and vice versa, but be careful of co-recursion).
To do so, you will need to hook into the selection event as described here<http://code.google.com/apis/visualization/documentation/gallery/linechart.html#Events>, and initiate "setSelection(...)" as described here<http://code.google.com/apis/visualization/documentation/reference.html#vissetselection> . I hope this helps.
