Displaying numeric range with supporting table

Hi sarjensystems1 ,

I have created a sample for your reference, please check the following steps as below.

1. Unpivot the table like that.

M code for your reference:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WilLSUdI1AhGmIMISRBgaAEkIYQgiQNIgbALEZkBsClEeGwsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [category = _t, Jan = _t, Feb = _t, Mar = _t, Apr = _t, May = _t, Jun = _t, Jul = _t, Aug = _t, Sep = _t, Oct = _t, Nov = _t, Dec = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"category", type text}, {"Jan", Int64.Type}, {"Feb", Int64.Type}, {"Mar", Int64.Type}, {"Apr", Int64.Type}, {"May", Int64.Type}, {"Jun", Int64.Type}, {"Jul", Int64.Type}, {"Aug", Int64.Type}, {"Sep", Int64.Type}, {"Oct", Int64.Type}, {"Nov", Int64.Type}, {"Dec", Int64.Type}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"category"}, "Attribute", "Value")
in
    #"Unpivoted Other Columns"

2. Close and apply, then we can create a measure like that to work it out.

Measure = 
VAR slice =
    MAX ( Slicer[Value] )
VAR ds = - slice
RETURN
    IF (
        NOT ( ISFILTERED ( Slicer[Value] ) ),
        BLANK (),
        IF (
            MAX ( 'Table'[Value] ) >= ds
                && MAX ( 'Table'[Value] ) <= slice,
            MAX ( 'Table'[Value] ),
            BLANK ()
        )
    )
