    Difference bar (By week) - Qlik sense

    Joanna Seldon

      Hiya

       

      I have a bar chart

       

      this shows Customer_ID totals for each week. 05/01/2015, 12/01/2015  column labelled =  Week_Beginning

       

      I need an expression that will show the difference between the two weeks

       

      Like

       

      count({$< Department = {"Catering"},  Week_Beginning - Date(Week)  >}Customer_ID)

       

      e.g

       

      05/01/2015 total was 30

      12/01/2015 total was 35  ...so customer difference bar will show the total difference of 5

       

       

       

      please help

          Hi Joanna

           

          I've faced the same problem few days ago

           

          I was needed to calculate the difference between sales from a week with the week before. It's seems that it is what you are looking for.

           

          below the way you may test It :

           

          count({$< Department = {"Catering"}>}Customer_ID)

          -

          rangesum(above(count({$< Department = {"Catering"}>}Customer_ID)),1,1))

           

           

          For my need I was able with this kind of formula to have this :

           

          bar chart :

           

          take Week Or Week_Beginning as dimension and the formula above as mesure.

           

          here the same as a table :

           

           

          hope this will help you

           

          Regards

           

          Bruno

              Hiya

               

              this works great thank you however, the subtraction is showing on the wrong week bar week beginning date, its showing the correct figure, but on the week before

               

              Dimension Week_Beginning

               

              e.g difference of 5 is showing on 05/10/2015, where it should be showing on 12/10/2015

               

              if you can help, please do but not to worry as chart looks ok

               

              Kind Regards
