   Actions	Description
   Aggregation method	Options: Sum (default), Average, Maximum, Minimum, and Count. This feature is available only for measure fields. The configured aggregation method appears before the field name. After setting an aggregation method for a measure field, you can configure filter conditions to display specific data. Note This feature is available only when the component's data source type is Data Table Resource.
   Filter	Add a field to the Filter section to use it as a filter item. You can then configure conditions based on this field to filter the displayed data. A maximum of 10 filters is supported. Alternatively, from the Dimension or Measure section on the left, you can click the triangle icon next to a field to add it to the Filter section.
