    Hi NuTek,

     

    You can use FIRSTNONBLANK/LASTNONBLANK function to get the first/last selected group.

    First Selected Group = FIRSTNONBLANK(Table1[Group],1)

    The formula below is for your reference.:smileyhappy:

    % Overlap for first Selected Group =
VAR firstSelectedGroup =
    FIRSTNONBLANK ( Table1[Group], 1 )
VAR count_of_overlap =
    CALCULATE (
        DISTINCTCOUNT ( Table1[Task] ),
        FILTER (
            Table1,
            CALCULATE ( COUNT ( Table1[Task] ), ALLSELECTED ( Table1[Group] ) ) = 2
        )
    )
        + 0
VAR count_of_task_XYZ =
    CALCULATE (
        DISTINCTCOUNT ( 'Table1'[Task] ),
        'Table1'[Group] = firstSelectedGroup
    )
        + 0
RETURN
    DIVIDE ( count_of_overlap, count_of_task_XYZ, 0 )

Hi NuTek,

 

Could you try using the formula below to create a measure, then just show the measure on the Card visual to see if it works?:smileyhappy:

% Overlap for XYZ = 
VAR count_of_overlap =
    CALCULATE (
        DISTINCTCOUNT ( Table1[Task] ),
        FILTER (
            Table1,
            CALCULATE ( COUNT ( Table1[Task] ), ALLSELECTED ( Table1[Group] ) ) = 2
        )
    ) + 0
VAR count_of_task_XYZ =
    CALCULATE ( DISTINCTCOUNT ( 'Table1'[Task] ), 'Table1'[Group] = "XYZ" ) + 0
RETURN
    DIVIDE ( count_of_overlap, count_of_task_XYZ, 0 )

Regards

Thanks for the formula.  The results look goodin your example...  Is there a way to not have to hardcode the "XYZ" and replace that with the selected value?
