Filter to only show unique values

Hey Roym ,

you can create a mesure that is checking if the item in each row contains a "Medium" value. Then you can filter the visual by that measure.

I created the following measure:

ItemsWitoutMedium = 
VAR vFilteredTable =
    FILTER (
        ADDCOLUMNS (
            -- Get unique values from [Item]
            VALUES ( myTable[Item] ),
            -- Count for each item the number of rows that contain "Medium"
            "@HasMediumVAlue", CALCULATE ( COUNTROWS ( myTable ), myTable[Classification] = "Medium" )
        ),
        -- Filter for [Items] without "Medium" values
        [@HasMediumVAlue] = BLANK ()
    )
RETURN
    -- return a 1 if the item has no "Medium"
    COUNTX ( vFilteredTable, IF ( [@HasMediumVAlue] = BLANK (), 1) )

And then you can filter the visual:

I uploaded my example file to this post.
