    Yesterday Value

      Hi,

      I am a beginner in QlikView.

      I made a Chart table, of which one of the Dimension is Day/Month/Year.

      My expression is SUM (FieldName)

      I have also some time (last week,month,year and set) list box from which I select the relevant period.

      My result is a table with Date and the relative Sum value

       

      My problem -I wish to have another column (expression) which show the value of the day before (I know that yesterday =today -1 BUT I am not using this in my chart.

      My wish full result should be

       

      Date               Sum          Yesterday's Sum          

      05/08/2015     10               7              

      05/08/2015     15               10

      05/08/2015     17               15

      05/08/2015     27               17    


      Any suggestions will be appreciated

          Is this SUM from yesterday or from line above?

          Your Date field has only one value, how did you get 7 for first line of yesterday's SUM?

           

          Check this doc

          Missing Manual - Above() and Below()

           

          If you are looking for value from previous row

              Hello,

              The sum column = quantity which arrives, each day for each container (we have many , of which I present by place, by type of material inside and so on) . This table chart show the sum by container , and aggregated by let Factory >> Factory Group >> Geographic Area. But this I have managed to do in the chart.

               

              Surly the first day, from which we started to collect data will have no yesterday info value.

              The 7 was just an  example from the previous day, but maybe I was not clear enough.

              The idea in total is , once I have the correct expression from the day before I can show in the yesterday column the GAP (today-yesterday) - that is my final goal.

               

              Your help will be appreciated.

              There are a few different approaches to take here.

               

              The easiest solution is using the above() function, which will always return the value from the chart line above the current line. Keep in mind that the first line in your chart will always show NULL as the above() value. This solution can only work in a chart by Date, of course.

               

              A more generic solution involves building a special table in your dataset. We usually call it the "As of Date" table. In this table, we associate the "display" date with the "transaction" date and assign a number of conditional flags, for example "Current Date" flag and the "Previous Date" flag. Your can find plenty of documents describing how to use the "As of Date" table, including my blog.

               

              I also described it in great detail in my book "QlikView Your Business".

               

              Cheers,

                Hi,

                 

                You need to try Above([Expression Name]) OR Above(Expression) for this.  Hope this helps you.

                 

                Regards,

                Jagan.

                  Hello,

                  Sorry for the late response BUT i have managed to bring en example:

                  Attached is a photo in which maybe my problem will be clear:

                  In this photo you can see that all the point are spread near one SINGLE Y-Axis greed line.

                  I would have expect the greed line to automatically changed, In this zoom-in example, to a range between 89-91 and with jump of 1/3 or 1/2 or something similar so the user can  see the little differences between the values.

                  AGAIN, I would have not expect the range to be smaller if one of the points was out of range.

                   

                  I would appreciate your input in this issue.
