From the dashboard of a group or meter you can add and rearrange widgets. At the top of the dashboard there are a couple of drop-down menus that let you choose the type of widget you want. It reads, “I want a…” next to the first drop-down, which lets you select the type of widget you want to add. The second drop-down lets you select, from all available options, what data to display. That could be an individual meter, or “Everything” meaning all of the meters in the group.
