You can't update the gauges without redrawing them, but otherwise this is possible. You need to set up a "ready" event handler for the dashboard, and pull the dataTable from one of the charts (using the chartWrapper's #getDataTable method). Group this data and use it to populate a DataTable for the gauges, then draw the gauges. Every time the range filter is changed, the dashboard updates, redraws, and fires the "ready" event, which triggers the update on the gauges. See an example built on your code here: http://jsfiddle.net/asgallant/H4xcX/
