Write proper instructions for various use cases

Opened this issue · 0 comments

What to aggregate and not aggregate in the PowerBI variable selector isn't always immediately clear.

Write instructions for the following:

  • Simple use case for single KPI
  • Aggregating a KPI over multiple levels (e.g. having a chart made up of the sum or median of several other KPIs)
  • Using the KPI matrix
  • Using the KPI summary table
