I still have no idea how you want to use this "filter", so I cannot really provide more information.
I have attached modified version of JMP's sample data table Big Class with dates.

It has date column (generated with formula) and column which should tell if date is in last 7 days (also formula)

There is also table script which will create graph builder to with local data filter
