The Top 10 section of the widget lists the top 10 active users. Each horizontal bar shows the total number/percentage of calls they made within the selected time frame.
The default view of active users appears in descending order (users who made the most number of calls to users who made the least number of calls). Click on the sort icon (arrow) to the left of the Calls column to sort in ascending order.
In the example, there are 5,356 active users, or 50.2% of the user base. There are 5,309 inactive users, or 49.8% of the user base. The top active users are Samantha with 3,821 calls, Bobbie with 437 calls, and Elta with 416 calls. The remaining active users each have fewer than 400 calls.
