No, it is not linked to date. This chart gives total data until today without any filter on time.
This report deals with a database where once the tickets are closed they are out of the system so the closed tickets are not there in the database for QV to pull.
So I would like to capture these numbers on every Monday morning & save it somewhere so that I can present it in another chart in the same report.
I think you could use a cyclic group with fields like month/week/date/hour for all your wanted periods and then toggling between them with the small cycle-button. It's quite easy: Creating Cycle and Drill Groups.
