Need Help!! How to calculate different row items

hi, 

 

I am trying to Calculate the difference between waves, but I am running into some issues. These waves are in rows and a text format ( not date ). I also want to select a specific wave and automatically show the "vs. prior wave" number. Thank you so much!!

Hi @Perezjav 

I build a table like yours to have a test.

Firstly, you need to transform your table by unpivot column like pranit828  replied before. (Select three wave columns)

Result:

Then build a Slicer Table.

 

Slicer = VALUES('Table'[Wave])

 

Add an Index column in Table.

 

Index = RANKX(FILTER('Table','Table'[Category]=EARLIER('Table'[Category])),'Table'[Wave],,ASC)

 

Build a measure and build a matrix visual to achieve your goal.

 

vs Prior Wave = 
VAR _select =
    SELECTEDVALUE ( Slicer[Wave] )
VAR _selindex =
    CALCULATE (
        SUM ( 'Table'[Index] ),
        FILTER (
            'Table',
            'Table'[Category] = MAX ( 'Table'[Category] )
                && 'Table'[Wave] = _select
        )
    )
VAR _current =
    CALCULATE (
        SUM ( 'Table'[Value] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Category] = MAX ( 'Table'[Category] )
                && 'Table'[Index] = _selindex
        )
    )
VAR _prior =
    CALCULATE (
        SUM ( 'Table'[Value] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Category] = MAX ( 'Table'[Category] )
                && 'Table'[Index] = _selindex - 1
        )
    )
RETURN
    _current - _prior

 

Result is as below.

Default:

Select Wave2/Wave3 in Slicer:

@Perezjav 

can you post the expected output for more information.

Hi @Anonymous 

 

The expected output is "vs. Prior wave" number. It is highlighted in the picture.

Thank you

Hi @Perezjav 

To start with unpivot all three wave column and then use the earlier function to get the previous wave data.
