Dear Team,

I have bellow Data set 

Project	Week	date	sales
ABC	week1	01/05/2020	10
ABC	week1	02/05/2020	20
ABC	week1	03/05/2020	30
ABC	week1	04/05/2020	40
ABC	week1	05/05/2020	50
ABC	week1	06/05/2020	60
ABC	week1	07/05/2020	70
ABC	week2	08/05/2020	17
ABC	week2	09/05/2020	18
ABC	week2	10/05/2020	19
ABC	week2	11/05/2020	20
ABC	week2	12/05/2020	21
ABC	week2	13/05/2020	22
ABC	week2	14/05/2020	23
	week2	15/05/2020	24

Basically I want to show in bar graph week1 data i,e  in X axis it will show from 01/05/2020 to  07/05/2020  (week1 data)
but in measure I want to show cumulative sales amount 
Example: for 01/05/2020 -- it  is 10 
                          02/05/2020 -- it is 10 + 20 (data of 1st May and 2nd May)

                          03/05/2020 --  it is 10 + 20 + 30 so on.....
