Help with set analysis

[#1]

I have forecast for 20 weeks in the future. I want a graph that only shows current week + 10 weeks. What set analysis could I use?

hi

have a look at the attach example

Now if I had actual sales details from the past months... how can I incorporate that into this graph to show me 4 weeks of previous sales?

The problem that I'm having here is that, for sales.. there is no snapshot week. only calendar_week. The goal of this graph is to see 4 weeks of actual sales prior to current week and also see 12 weeks of future forecast data.

example: if the current week in the example is 9/1/2014. I want to see actual sales for 8/25/2014, 8/18/2014, 8/11/2014, 8/4/2014 and then I want to see future forecast from 9/1/2014 to 11/10/2014 ............see sample app
