Returning Value of Table Based on Ranking

Hi leems101 

You can create a calculated colum rank within partitioned by each article and another calculated column for the total views.

Rank = 
RANKX (
    FILTER ( 'Table', 'Table'[Article] = EARLIER ( 'Table'[Article] ) ),
    'Table'[ Views],
    ,
    DESC,
    DENSE
)

Total Views by Article = 
CALCULATE ( SUM ( 'Table'[ Views] ), ALLEXCEPT ( 'Table', 'Table'[Article] ) )

And a measure to return concatenated values

My Value = 
VAR _source =
    SELECTEDVALUE ( 'Table'[Source] ) & " "
VAR _views =
    SUM ( 'Table'[ Views] )
VAR _percent =
    FORMAT (
        DIVIDE (
            _views,
            CALCULATE ( SUM ( 'Table'[ Views] ), ALLEXCEPT ( 'Table', 'Table'[Source] ) )
        ),
        "0%"
    )
RETURN
    _source & FORMAT ( _views, "#,0" ) & " Views " & "(" & _percent & " of total)"

Note: Since Total Views and Rank are calculated columns, this approach is not fully dynamic, as calculated columns do not respond to slicer selections. For example, excluding Home using a slicer will not update these values. A more dynamic solution would require a disconnected table and more complex DAX, which involves additional development effort.
