It is important to understand what data you are looking at in each widget. For example, you should know if you are viewing data for a particular package, region, etc. You can view a summary of this information by placing your cursor over the widget title bar. The tooltip shows the By, date range, sort, filters, and more.
You can also view information about specific items within a widget by placing your cursor over the item. (Some mobile devices may not support mouse-over tooltips.)
