Percentage of total per week - stacked barchart

[Sander1401]

Hi all,

I have a visual with sales per week in a stacked bar chart, split by brand.
Now I want to make a parameter tot switch between the absolute numbers and % of total per week.
So like below:

week	Brand	Sales	% of total
1	A	50	33%
1	B	100	67%
2	A	75	50%
2	B	75	50%
3	A	30	20%
3	B	120	80%

I know I can do this with bookmarks, but I already using some bookmarks, and I want to cover it by using only 1 parameter to switch between these measures.

What should be my formula?

HI @Sander1401,

You can create a parameter table with category types that use on the slicer as selectors to interact with measure expression to switch different values.

Notice: Dax expression does not support returning two or more display formats except you change the measure data type to text.

Thanks, I think my question was somewhat unclear, my problem was the dax formula of the last column...

Hi @Sander1401,

You can try to use the following measure formula if it is suitable for your requirement:

formula =
DIVIDE (
    CALCULATE (
        SUM ( Table[Sales] ),
        ALLSELECTED ( Table ),
        VALUES ( Table[Week] ),
        VALUES ( Table[Brand] )
    ),
    CALCULATE (
        SUM ( Table[Sales] ),
        ALLSELECTED ( Table ),
        VALUES ( Table[Week] )
    )
)

@Sander1401 , Measure slicer can help. Or calculation group can help. Format change will happen in calculation group only
