Variable time

[#1]

Hello

I would need help. I have 2 tables that your union is the passport. The first table is sales per day, and the second table is trips per day.

I would like to create a variable that when selecting the date I would filter the data of trips of a day and sales from the day of travel to 72 hours more and I can see it in two graphics

Can you post a small qlikview document that explains the problem?
