Oh! Do you want to show entire month? Me too, but I do not know how to do it, sorry.
So, we want relative time: “This month” instead of “This month so far”
This month so far: now/M
(relative time)
This month: 0M/M
(time shift)
EDIT: I get it!! First time to me
Use “time shift” field: today is 2021/03/12 (for future viewers and ignore the title of the graph)
