Aggregation is a function that applies to the entries of a certain field. It allows you to see the function of your choice — Sum, Minimum, Maximum or Average value of a certain field. To add Aggregation to your Library, you need to choose it whether during the creation process or while Editing an existing Library:

  • Click Aggregation, then press Add function to start. Click Edit to rearrange the existing functions.
  • When adding a function, first you need to specify the type of a Function (Sum, Minimum, Maximum or Average).
  • Choose a Field to apply this function to.
  • Set a Prefix to define how this function will be shown to the end-user.

This is how Aggregation is displayed while browsing the Library (Average duration line):

You can Hide or Show aggregation anytime, just tap the  icon and choose the required option.
