Using Measures as Axis in line chart

[foyiq]

I would like to build a simple graph like the following (from Excel - X-axis shows running total quantity, and the Y-axis shows per ton margin.

😞

Now, I managed to put this in PBI using the index column, and the best result I got is this:

As you may see, this scatter plot is not presentation-friendly. As the values I use are measures, I am not being able to get the same result from line graphs. I also could not manage to build a calculated column for running total quantity. The measure formula is as follows:

Q-ty(tn) running total in Index = 
CALCULATE(
	SUM('Result'[Aggr.Qty]);
	FILTER(
		ALLSELECTED('Result'[Index]);
		ISONORAFTER('Result'[Index]; MAX('Result'[Index]); DESC)
	)
)

Please, advise me on getting the desired output, which is a simple line with running total qty on X and per ton margin on Y.

@foyiq,

Create a calculate column that represents running total using DAX below, then create line chart and check if you get expected result.

Running Total COLUMN =
CALCULATE (
    SUM ( 'Result'[Aggr.Qty]);
    ALL ( 'Result' );
    'Result'[Index]<= EARLIER ('Result'[Index])
)
