Creating week over week chart

[#1]

Hi there. New to qlikview and wanted to see if anyone could help figure out how to create a rolling 7 day week over week chart.

Do you have idea how this chart should look like?

What values do you like to analyse?

What are your input data?

Thanks for your reply. The look is actually two bar charts…one showing the target and the other showing the actual. There are several metrics that I am graphing and have done a rolling 30 day chart— I want the same look and feel but as a rolling 7 day. It should look like this:

How do you know your chart start and end dates?

Does user selecting it?

I think that you need set analysis to manage dates. But i undestand, that with your first day on the chart you would like to see value fromn that day and value existing 7 days earlier. So, this may be done if you will have additional calendar - dimension. You may create in this dimension 2 rows for each date. The table may have fields like this:

Date_WD, RefType_WD, Date

2014-01-08, 'Curr', 2014-01-08

2014-01-08, 'Prev', 2014-01-01

2014-01-09, 'Curr', 2014-01-09

2014-01-09, 'Prev', 2014-01-02

.........

.........

So, in your chart you will use Date_WD as Dimension.

Date field will be reference to field in your normal calendar.

RefType_WD will be differentaiator, which you will use in your set analysis.

Let me know if this concept meets your requirments and if you need more help.
