I want to count unique visitors each day, and then sum over the week. At present I have a unique visitor segment and I can do it by day/week/month etc. But if I count it by week it only counts a single visitor once, rather than the sum of the daily counts. So if a user visited 3 times in a week, I would see that each day. But the week total would not be 3, it would be 1.
I have tried a few calculations but I somehow need to count it by day then sum it across the week.
