Do you have any idea why Daily, Weekly & Monthly Unique Visitor Metrics not showing up in the Workspace? When i am trying to add Daily Unique visitor Metric its not available in Workspace. Only Unique Visitor metric is available
Thought of reverting the discussion a long back, but somehow was packed and unable to reply.
As said by Ashok Kumar, it is a very good idea to Sum the Column to have Daily Unique Visitor but will work only on aggregations.
Explanation goes below:
Assume, you want to understand daily Unique Visitors for May - Jul 2019. You can go to Reports & Analytics interface and just drag the Unique Visitors to it : Below the Screen Grab.
In Work Space, you cannot do it by month, rather you can aggregate the numbers by each month.
I.e. If you take Day Dimension and Unique Visitor as a metrics to Sum the column, you will only get 8,315 as the answer which is Daily Unique Visitor for all 3 months combined : Below the Screen Grab.
So if you want to understand Daily Unique Visitor by month, either you need to create 3 Free Form Tables with different Time Period to Sum the column or compare it with time periods to Sum the column like below in a Single Free Form Table.
Now you can see that Daily Unique Visitors Number matching the column aggregations.
