An often-overlooked feature of AM360 dashboards is the ability to drill deeper into tabular data views by expanding column summaries, where the message “Hover over a column and click -/+ to remove or add groupings” is displayed. Hovering over column headers exposes a plus sign to expand the results. Clicking the plus sign drills into the next layer of data, revealing specific details of the summary. Pressing the minus sign returns the table view to the original summary data.
