Mode mesaure for Virtual Table

Hi, I'm trying to create a MODE measure and apply to a given virtual table given below: VAR VrtTable= UNION( ROW("VrtValue",[Product Count]), ROW("VrtValue",[-1M]), ROW("VrtValue",[-2M]), ROW("Vrt...

    Sure, just saw your update 🙂

     

    I would then lump the two conditions (nonblank [VrtValue] and [Frequency] > 1 ) into a FILTER around GROUPBY:

    VAR VrtTable =
    UNION (
        ROW ( "VrtValue",[Product Count]),
        ROW ( "VrtValue", [-1M] ),
        ROW ( "VrtValue", [-2M] ),
        ROW ( "VrtValue", [-3M] ),
        ROW ( "VrtValue", [-4M] ),
        ROW ( "VrtValue", [-5M] )
    )
VAR ValueFrequency =
    FILTER (
        GROUPBY ( VrtTable, [VrtValue], "Frequency", SUMX ( CURRENTGROUP (), 1 ) ),
        NOT ISBLANK ( [VrtValue] ) && [Frequency] > 1
    )
VAR Mode =
    -- MINX returns the smallest value in case of ties
    MINX ( TOPN ( 1, ValueFrequency, [Frequency] ), [VrtValue] )
RETURN
    Mode

Dear Owen,
The solution you've provided works almost perfectly. Just one criteria is needed:
Somehow we need to generate the MODE result only if FREQUENCY is MORE than ONE.

 

 

As you can see - The mode result is right when the frequency is more than one. So, Where should I put thia criteria, please advise.

Thanks in advance,

..And one more thing - The grouping should ignore BLANK values. As given below:

The mode of that highlighted group should give 2400 as the Mode result. Now it's blank.
