I tried this but it didn't workout for my scenario
This gave me a list of all dates but I am still unable to filter to only 7 days. I created a parameter select a date which helps people select a start date. I am trying to create an end date filter which will do something like this:-
if select a date = today() - 7 then display date list for 7 days
if select a date is < today() -7 then display date list for how many ever days until today.
Do you think it is possible to filter the show missing date list values?
