    2 date ranges within Set analysis  - to create a setp change in a SPC

    sarah worthy


      Please could you help me? I am fairly new to Qlikview and I am scrabbling around to get info.  I am creating an SPC chart in Qlikview and all appears as it should.  However I have been asked to create appropriate step changes and to allow a user to input their own into the chart.

       

      For Example. a number of weeks the data runs fairly consistently as expected... then between a range of weeks the data changes dramatically due a special circumstance.  I would like to have the limits showing one date range and then change to reflect the second date range.

      This chart in excel  reflects the change.

      how do I write the set analysis to move the limits on a different date range ?

      Thank you
