    Finding the avg value of the last 3 weeks:

    Abdallah Shouli

      Hello, I'm new to Qlik and I'm trying to figure out a rather difficult expression to write... I have provided an example of the data below:

       

      I have a table with values taken every day.. I am trying to figure out an expression so that the values shown are calculated as followed, if I choose date 12/28, a new valueB will be calculated by taking the average of the value of the  7, 14, and 21st  day BEFORE the date selected.

       

       

       

      I would also like to have that average subtracted from the actual value shown for 12/28 below:

       

       

      Value B =  Avg of Value (12/7, 12/14, 12/21)

       

       

       

      Value C =   Value A - Value B

       

      so that I can result : if( value C > 3.00) ... flag Value A below.

       

       

       

       

       

       

       

       

      DateValue A
      12/75
      12/143
      12/212
      12/288
