Cumulative chart does not cummulate

[Anonymous]

Hi Power BI Community!

I want to show a cumulative chart after what delivery time span all deliveries had reached the customers.

At first the chart looks fine but the line must always go up because it should add the numbers. So the fram of 10-15 must be bigger than 5-10 and so on.

Here is my calculation:

On Axis:
Delivery time frame =

var _diff = datediff([PO Date] , [delivered on],DAY)

return

Switch ( True() ,

_diff <= 2, " 0-2" ,

_diff <= 5, " 2-5" ,

_diff <= 10, "5-10" ,

_diff <= 15, "10-15" ,

_diff <= 30, "15-30" ,

"more than 30"

)

On values:

Cumulative PO to delivery =

CALCULATE([Total PO],

FILTER(ALLSELECTED(TrackET),

TrackET[Delivery time frame]<= MAX(TrackET[Delivery time frame])))

Total PO is just 

Total PO = SUM(TrackET[PO to delivered on])+0
PO to delivered on = Delivered on date - PO Date

Thank you for your time!

@Anonymous , I think this because of sorting issue. I am assuming you have also created a sort column as I can see 10-15 at the correct position

do this on sort column

Cumulative PO to delivery =
CALCULATE([Total PO],
FILTER(ALLSELECTED(TrackET),
TrackET[Delivery time frame sort]<= MAX(TrackET[Delivery time frame sort])))

where sort would be like

Delivery time frame sort =
var _diff = datediff([PO Date] , [delivered on],DAY)
return
Switch ( True() ,
_diff <= 2, 1 ,
_diff <= 5, 2 ,
_diff <= 10, 3 ,
_diff <= 15, 4 ,
_diff <= 30, 5,
6
)
