Cards the section contains data items used to calculate values displayed within cards.
Data items are arranged in containers. Each data item container can hold two data items. The first item contains actual data and the second item (optional) contains target data. If both items are provided, cards show the difference between actual and target values.
Series the section contains data items whose values are used to label cards.
Sparkline the section is used to provide a date-time dimension whose data will be used to visualize values using sparklines.
To control how cards are arranged, use the Content Arrangement group in the Design Ribbon tab.
