Aggregates over time

[IvanMislav]

Hi,

I need some help. I have a Users table with columns User_Name, Joined_Date and Deleted_Date . I would like to create a graph that shows total number of users over time. Does anyone have an idea how can i do this?

Thanks

1) If you haven't already, add a table with dates, say, Dates[Date],

2) Add a measure:

ActiveUsers = COUNTROWS(FILTER(USERS, 
	AND (Users[Joined_Date]<LASTDATE(Dates[Date]) ,
	Users[Deleted_Date]>LASTDATE(Dates[Date]))))

3) Plot ActiveUsers against Dates[Date],

Note: alternatively use FIRSTNONBLANK(Dates[Date],TRUE) instead of LASTDATE(Dates[Date])
