How to change Matrix subtotal aggregation to a % Change instead?

[AllenVaysberg]

Running into a "fun" problem.  Have a report that looks like below.  The State values in Columns are based on a State column and the 2 values are based on a filter in the Matrix visual.  I am trying to create a % change and can't seem to figure it out since I don't have 2 different columns, I have just 1 that shows 2 or 3 values based on a filter.  Any good way you have solved this?  Appreciate all the help!

hI @AllenVaysberg ,

To make the calculation easier I would remove the total row and unpivot the location columns and then use this measure:

Percentage = 
DIVIDE (
    SUM ( 'Table'[Value] ),
    CALCULATE ( SUM ( 'Table'[Value] ), ALLSELECTED ( 'Table'[Category] ) )
)

Please see attached pbix for details.

Thanks for the effort but I don't want a % of total, I need a % of change between the 2 values.  So 150 to 175 what is the % of change.
