Matrix tooltip

Hi GrayGunn5 ,

I think you can try to create this measure to filter your visual in your tooltip page.

Filter = 
VAR _C1 =
    SELECTEDVALUE ( Classification[Classification] )
VAR _C2 =
    SELECTEDVALUE ( Classification_dup[Classification] )
VAR _VALUES =
    CALCULATETABLE (
        VALUES ( Data[IdPerson] ),
        FILTER ( ALL ( Data ), Data[Classification] = _C2 )
    )
RETURN
    IF ( _C1 = _C2, 0, IF ( MAX ( Data[IdPerson] ) IN _VALUES, 1, 0 ) )

Here I create a table visual by 'Data'[IdPerson] and keep all filters from 'Classification'[Classification].

Add this measure into visual level filter and set it to show items when value = 1.

Result is as below.
