    Help with Window_AVG([My Measure], First(), First() + 7)

    Jonathon Carrell

      I'm currently using Tableau Desktop v. 8.3.

       

      For some reason Window_AVG([My Measure], First(), First() + 7) returns null.  Am I missing something?

       

      Window_AVG([My Measure], First(), Last()) returns the expected value, but I want to base this center line on only the first few rows.

       

      Any insight would be greatly appreciated.

       

      Thanks,
