I have a problem in which I have to design a chart in which certain number of dimension values need to be displayed. Let me explain you with an example. The selections can be made in any of 'Half Year', 'Quarter', 'Period' or the 'Week' itself. On such a selection, there are to be displayed, 13 weeks only, from the end i.e. the latest 13 weeks in the selection as a dimension in the aforementioned chart. I can use some help. Thanks in advance!
