Select Viewlet from the side menu of Admin Settings to specify maximum data points per viewlet page and maximum data groups in summary viewlets.
Maximum Data Points per Viewlet Page is the specified data amount that can be displayed in each viewlet. When a viewlet has more data records than the specified limit, additional pages will be present to view all data. The amount of data points displayed can be manually changed, by configuring the viewlet size.
The Maximum Data Groups in Summary Viewlet defines how many data groups can be combined into one summary viewlet.
