The Action Item Progress displays the amount of Action Items with approaching or past due dates.
In this example, there are several items with a due date more than 3 days in the past, four Action Items due within 7 days, and six Action Items with a due date more than 15 days in the future.
Selecting any of the bars on the widget will open an Evaluations list pop-up, listing the Evaluations that match the progress filter you clicked on. Using the View link will open a new tab with the Action items for that evaluation.
