Based on your comment and updated question, you can do it as you intend, though it isn't as straight-forward.
NOTE: I did this very quickly and with a random data set, so it will be important for you to test this thoroughly with your data set.
- Create a parameter control that the users will use to change the selected date range. I created this as a list of strings with values that I can use directly in a calculated (after simple casting):
- Create a calculated field that you will use as a filter that references the selection of the parameter control. It tests to see if the difference (in weeks) between the maximum date in the view and the date of any given row is less than the value of the parameter.
Calculation: INT([Date Filter Parameter]) > DATEDIFF("week",ATTR([Date Field]),WINDOW_MAX(MAX([Date Field])))
- Place the calculated field in the filter box and set it to True.
You will be able to filter your data like so:
