Calculate difference % with all values

[jereaallikko]

Hi,

I am facing a problem with calculating % difference. In a nuthsell, I would like to visualize the difference of X and ALL Values in a table separately. An example data and use case below:

Ideally, I am looking for a solution (DAX or something else) to calculate the "Number" difference % between 20943_0003 and the rest of the values separately. Similarly, difference % between 29839_0002 and the rest of the values separately, then 29853_0001 and so on..

The idea is that the user can choose and filter ANY ID and see the % difference to every ID Number.

The result what I am looking for is this:

Or this:

And same for every Number of each ID. A bit difficult to explain, but hopefully you get the idea. 

Is this even possible to do? Anyt tips?

Br,

Jere

Hi @jereaallikko ,

Just as tamerj1 said, you need create a new table with all IDs and don’t create any relationship between these two tables. Then, take the ID column in the new table to create a Slicer.

But after that, you need create a Measure like this.

Difference =
VAR SelectedID =
    SELECTEDVALUE ( 'NewTable'[ID] )
VAR SelectedNumber =
    CALCULATE ( MAX ( 'Table'[Number] ), 'Table'[ID] = SelectedID )
RETURN
    DIVIDE ( MAX ( 'Table'[Number] ) - SelectedNumber, SelectedNumber )

Then the result will look like this.

If this post helps, then please consider Accept it as the solution to help the other members find it more quickly. If I misunderstand your needs or you still have problems on it, please feel free to let me know. Thanks a lot!

Hi @jereaallikko 

you can start with creating simple disconnected Slicer Table. > New Table:

Slicer Table =
VALUES ( Table[ID] )

Then create your difference measure 

Difference =
VAR SelectedID =
    SELECTEDVALUE ( 'Slicer Table'[ID] )
VAR CurrentID =
    SELECTEDVALUE ( Table[ID] )
RETURN
    IF (
        COUNTROWS ( ALLSELECTED ( 'Slicer Table'[ID] ) ) = 1,
        DIVIDE ( CurrentID - SelectedID, CurrentID )
    )
