    Add a column to data source

    Pacifico Fratta

      Hi, I'm new to Tableau. In the following snapshot of a table (txt file), I want to compute the average of the Execution_time column until the Sample_id = 30, and restart the procedure for the next 30 Sample_id, till the end of dataset. I want to write the computes average values in another column, say "Average".

       

      Sample_id      Execution_time      Average

      1                     2.5                             4

      2                     3.5                             2

      3                     4.5

      ..

      30

      1

      2

      3

      ..

      30

       

      I want something like the previous example or, alternatively, a new table with "Total size MB - Partitions - Average" columns.  How can I do it?Schermata 2017-05-08 alle 17.21.59.png
