Finding paths connected through a node. Data filtering

  I have a table which resembles the below. The columns explained: Main contains the name and the pathway number. The Main can therefore contain nodes called Str1 or Str2, which indicates where it...

    Try

    Connected Mains = 
VAR InitialNodes =
	UNION( VALUES( 'Table'[Str1] ), VALUES( 'Table'[Str2] ) )
VAR ConnectedMains =
	CALCULATETABLE(
		VALUES( 'Table'[Main] ),
		'Table'[Str1] IN InitialNodes
			|| 'Table'[Str2] IN InitialNodes,
		REMOVEFILTERS( 'Table' )
	)
VAR ConnectedMainsExlcudingCurrent =
	EXCEPT( ConnectedMains, { SELECTEDVALUE( 'Table'[Main] ) } )
VAR Result =
	CONCATENATEX(
		ConnectedMainsExlcudingCurrent,
		'Table'[Main],
		", "
	)
RETURN
	Result

    If I understand correctly you want a list of mains and all the nodes they are connected to. You could do another table like

    Main All Connected =
GENERATE (
    ALLNOBLANKROW ( 'Main Neighbours'[Radialnr-rettet] ),
    DISTINCT (
        UNION (
            CALCULATETABLE ( VALUES ( 'Main Neighbours'[Connected To] ) ),
            CALCULATETABLE ( VALUES ( 'Main Neighbours'[Neighbours Neighbour] ) )
        )
    )
)

Hi johnt75 

I have a followup issue, which I cannot seem to solve.

The above solution you provided gives me the "Neighbors" of the Main, however when I want the Neighbors-Neighbor, I just put the Main in a new table or matrix and get the Neighbors-Neighbor. This is viable but not practical.
However, in this method I will have to make 3 tables just to show these information, and I only have the choice to click on Neighbors-Neighbor which filters the picture, yet I have no choice in having Neighbor table to show me the picture.
Is there a way to collate them all into 1 view or 1 table/matrix and each Main is separately clickable.
I have a picture you can see what I mean.

 

Is the filter collider a good idea to see the Neighbors-neighbor?

however at the moment it shows the previous chosen Main:

No idea if this will work but these are my thoughts, for what they're worth.

You could try creating a field parameter which includes columns from Main, Main's neighbour and Neighbour's neighbour. Put the field parameter on each of the slicers, and set a filter on the field parameter in each slicer, so each one shows a different column.

On the chart, also use the field parameter as the value. I'm hoping that when you select one of the values from the slicer that selection, along with the field parameter filter, will get applied to the chart and show the correct info.
