Line Charts with Cumulative values

Hi GaRaGe,

First, you should create a calculated column to get a number format month. If we use the Jan, Feb, Mar and so on. Month will order by alphabet.

Month! = SWITCH(Test[Month],"Jan",1,"Feb",2,"Mar",3,"Apr",4,"May",5,"Jun",6,"Jul",7,"Aug",8,"Sep",9,"Oct",10,"Nov",11,12)

Then create two measure for cumulative spend over month. 

Target = CALCULATE(SUM(Test[Spend]),FILTER(ALL(Test),Test[Month!]<=MAX(Test[Month!])&&Test[Metric]="Target"))

Actual = CALCULATE(SUM(Test[Spend]),FILTER(ALL(Test),Test[Month!]<=MAX(Test[Month!])&&Test[Metric]="Actual"))

Finally, create a line chart, select the [month!] field as axis, the two measures as value level.



Please feel free to ask if you any issue.
