Calculate difference between values in different columns

Hi,

 

I would like to build the Excel visualization (see screenshot) in PBI. I assume this is possible with a DAX measure? I've been playing around with some DAX functions and tried some solutions from previous posts, but I cannot get my head around it.

 

It basically needs to calculate the difference in Amount compared to the Amount of the previous date. It should be dynamic; new dates can get added to the table.

 

Any hints, tips are appreciated.

 

 

Best regards,

Armand

    az38 thank you for your proposal, but unfortunately it did not work out.

     

    Eventually I found the solution using the following measures:

    1. PreviousDate
    2. Amount previous date
    3. Diff with prev date
    4. Diff %
    PreviousDate = 
    VAR CurrentDate =
        SELECTEDVALUE ( 'Sheet1'[Date] )
    RETURN
        CALCULATE (
            MAX ( 'Sheet1'[Date] );
            ALLSELECTED ( Sheet1 );
            KEEPFILTERS ( Sheet1[Date] < CurrentDate )
        )
    Amount previous date = 
VAR Prev = [PreviousDate]
RETURN
CALCULATE (
        [Total Amount];
        Sheet1[Date] = Prev
    )
    Diff with previous = 
[Total Amount] - [Amount previous date]
    Diff % = 
    IF (
        ISBLANK ( [Diff with previous] );
        BLANK ();
        DIVIDE ( [Diff with previous]; [Amount previous date] ) * 100
    )

    Hi Anonymous 

    try a measure

    diff = SELECTEDVALUE('Table'[Amount])-calculate(FIRSTNONBLANK('Table'[Amount];1);filter(ALLEXCEPT('Table';'Table'[Article]);'Table'[Date]<selectedvalue('Table'[Date])))

    do not hesitate to give a kudo to useful posts and mark solutions as solution
