count by measure

[parry2k]

hi there,

I have  a calculated measure to calculate the share % of each category, based on category share there is ranking, if % > 20 then A if % > 10 then B else C

I added the measure for ranking as well, so in table category, %  and rank all looks good.

I want to count number of categories under each rank. What is the best way to achieve it?

thanks,

P

Try with this modification:

RANK =
VAR Share = [% share]
RETURN
    IF ( Share > 0.10, "A", IF ( Share > 0.05, "B", "C" ) )

Just to add more there will be slicer on category so the solution should work if any value is selected in a slicer.

HI @parry2k

Try this approach

Create a calculated table of all available RANKS (a,b,c,d etc)

RANKs = DATATABLE("RANK",STRING,{{"A"},{"B"}})

Then you can use this MEASURE to count categories against each RANK

Measure =
COUNTX (
    FILTER (
        ALLSELECTED ( Table1[Category] ),
        [RANK] = SELECTEDVALUE ( RANKs[RANK] )
    ),
    1
)

I created a small sample file (which is attached)

Hope it is useful

Hi @Zubair_Muhammad

I was doing the same but here are few changes which I made and it is not working:

- No sum on amount in table to calculate %

- % is calculated based on allselected

- small change in rank formula to get 3 values

- made changes to "measure" to allselected instead of allselected(Table1[Category]) 

now if you select multiple values in slicer, you don't get correct result. Take a look, I made the changes in attached.

Thanks,

@VvelardeThanks for getting back. Although I sorted it out but wanted to check how you experts will do. I will test your solution. Cheers!!

Sorry I couldn't get time to look into this after my intial post.

Victor is right ..Great observation....this modification should fix the matter for Count of Categories

"The measure "RANK" inside FILTER (or any other ITERATOR function) will modify itself according to the Table passed as argument inside the ITERATOR. Thats why it should be put in a variable first"

Attached revised file as well

To get the distinctcount of categories

DistinctCount_Categories =
VAR myrank =
    SELECTEDVALUE ( RANKs[RANK] )
RETURN
    CALCULATE (
        DISTINCTCOUNT ( Table1[Category] ),
        CALCULATETABLE (
            VALUES ( Table1[Category] ),
            FILTER ( Table1, [Rank] = myrank )
        )
    )
