In fact you need to display for each month, the value for the month and the value for the 11 months before this month.
You can use the chart function before() or above() if you want to calculate the sum of last 11 months only on values in graph.
Or if you need a real moving sum, you can follow this thread http://community.qlik.com/message/229267#229267
Thank you for the reply. Unfortunately it's not exactly what I'm looking for. If you look at the attachment with selections Year = 2012, Month = May and FinncPriod = 111, you will see that the column with the monthname 'May' has the qty's for May 2012 underneath. These qty's are correct. In the column to the left of it (with the light red shading) I want the qty's for Apr 2012 and in the column to the left of that one, Qty's for Mar 2012 and so on.
So I'm hoping to achieve this with set analysis without going through building a calender. One would think a set analysis
or something similar should give me the Qty's for Apr 2012? FinncPriod after all has a unique no for all transactions in a particular month.
