Progressive substraction in chart

[CamillaDiPassio]

Hello everyone, 

I have a problem with the creation of a chart.

The data I have are as follows:

- Part number = a set of unique code

- Created Date= date of creation of the code

- Modified Date = date of modified of the code 

- Outcome= the code is active or not (True/False)

I have to create a waterfall chart where I have by month the active codes minus the subtraction of those no longer active in that month (using the modified date). 

I got the following chart using these formulas:

- controllo = if(AND(Registry[ToControl]=false, Registry[Created].[Date]<>Registry[Modified]),1,0)    --> creation of a new column with a binary output

- Quanti meno = -(DISTINCTCOUNT(Registry[PartNumber])-sum(Registry[controllo]))  --> creation of a measure by month

But in this chart I can't insert the progressive substraction, so I would to see by month the earlier number of code minus the code that are no longer active. Any suggestion?

Thank you!

Hi,

Please indicate the expected outcome. Is this it?

Also note that the seed value (the starting value) is in the same month as some of the reductions - that cannot be shown in the waterfall chart unless you go down to day level.
