Most dashboards support drill-downs. A drill-down allows you to see more detailed information about the element you have clicked on.
Click an element on the dashboard. Such as a metric, an area of a world-map, or a segment of a chart. If that element supports drill-downs then you will see a small menu pop-up.
Select the appropriate option from that menu to see the drill down.
You will often be able to download the detailed set of data directly from the drill-down too.
