Order tooltip values descending

While you can use a page tooltip, creating a calculated table to materialize measures is not the right approach. Calculated tables are static and do not respond to slicers or cross-filtering, even if the measures they reference do. A better solution is to use a disconnected table that lists the measure names in a column, then reference that column in a measure to return the corresponding value based on the current row.

The Hex colums above are the to be used to create a DAX-generated conditional formatting icons. SVG Conditional formatting icons do not accept hexadecimal values starting with # so %23 is used instead

Circle Icon = 
VAR _Color =
    SELECTEDVALUE(MeasuresToBeSorted[Hex2])

VAR _SVG =
    "data:image/svg+xml;utf8," &
    "<svg xmlns='http://www.w3.org/2000/svg' width='20' height='20'>" &
        "<circle cx='10' cy='10' r='8' fill='" & _Color & "' />" &
    "</svg>"

RETURN _SVG

Notice that the sorting of the measures in the imabe below changes.
