Force Directed Graph with Retrospective

Hi there,   In a force directed graph, I'm looking to see all interactions related to a node when a slicer is used.    In the below you could see once Atlanta is selected, it shows only ATL - BOS...

    HI Anonymous ,

     

    Create a table with all the airports then add the following measure:

    Filter Airports =
IF (
    VALUES ( 'Table'[Destination] )
        IN VALUES ( Airport[Airport] )
            || VALUES ( 'Table'[Source] ) IN VALUES ( Airport[Airport] ),
    1
)

     

    Now use this measure to filter out the Force direct and the Airport has your slicer:

Thanks Miguel. Almost close. But the below is what im trying to get.  Any thoughts. I'm not trying to count the flights.

 

Please dont get carried away by the word "Destination". The intent of the tree is show only connections between airports and what flights. Atlanta connects 4 airports. So when atlanta is selected, tree's first column should only be 4 airports.  Next tree column is flights.

Hi Anonymous ,

 

Since you want to different interactions  and with a single slicer you need to make a second table for the airports and the add the following measure:

Filter Decomposition = 
VAR temp_table =
    FILTER (
        ADDCOLUMNS ( 'Table', "FilterAir", [Filter Airports] ),
        [FilterAir] <> BLANK ()
    )
VAR airportsselection =
    UNION (
        FILTER (
            SELECTCOLUMNS ( temp_table, "Airport", 'Table'[Source] ),
            NOT ( [Airport] IN VALUES ( 'Airport - Slicer'[Airport] ) )
        ),
        FILTER (
            SELECTCOLUMNS ( temp_table, "Airport", 'Table'[Destination] ),
            NOT ( [Airport] IN VALUES ( 'Airport - Slicer'[Airport] ) )
        )
    )
RETURN
    COUNTROWS (
        FILTER (
            'Airport  - Decomposition Tree',
            'Airport  - Decomposition Tree'[Airport] IN airportsselection
        )
    )

Now use the column on the second airport table to be you column on the decompostion tree and filter the decompositon by the previous measures:
