New user having trouble with cumulative totals.

[Anonymous]

Hi all, 

New to Power BI and I'm having trouble creating cumulative totals.

I want to visualise the cost accociated with certain groups and sites all in one Line Chart visual.

So grouping the cost by e.g. Site, Group and run the total based on date so I have one line for each breakdown.

Here is a set of dumpy data similar to what I am working with. 

Date	Agent	Group	Cost	Site
01/01/2019	Tester 1	ABC	2400	Hogwarts
02/01/2019	Tester 1	ABC	2400	Hogwarts

-- First of all, you should have a proper DATE TABLE in your
-- model that links on dates to the Date column in your,
-- let's call it Costings - table. So, let's say the date
-- table is called Calendar (please find out how to create
-- a proper date table in a tabular model). Then hide the
-- column Date in your Costings table. Once you've done that,
-- you can use this measure:

[Cumulative Total] :=
var __lastVisibleDate = LASTDATE( Calendar[Date] )
RETURN
	CALCULATE(
		SUM( Costings[Cost] ),
		Calendar[Date] <= __lastVisibleDate,
		ALL( 'Calendar' )
	)
