Keep only n first rows of a visual table based on a metric value ?

Anonymous — Wed, 26 Jan 2022 10:02:15 GMT

Hi !

I would like to visualy keep in my table (table as a visualization, not in terms of data source) only n first rows based on the value of a metric column for a category.

Exemple : in the below table, I would like to display only the 2 most sold product id in the category A and the 2 most sold in the category B. So I will visualy have only 4 rows in my table.

How would you do that ?

Thanks 😉

product id	category 1	category 2	sales
FDFSDF	A	X	543554
HFGHFGH	B	X	34234
YRTYY	A	Y	7567
ERERZR	A	X	234
gDFGDG	B	Y	23434
GFDGDFG	A	Y	5345345
JHGF	A	Y	4324
qFGD	B	Y	543354
gdFGG	B	X	5345345

Hi,

You can create a filter measure like this:

Filter top 2 of categories =

Var catA = RANKX(all('Table (7)'),calculate(SUM('Table (7)'[sales]),'Table (7)'[Category 1]="A"),,DESC)

Var catB = RANKX(all('Table (7)'),calculate(SUM('Table (7)'[sales]),'Table (7)'[Category 1]="B"),,DESC)

Return

IF(or(catA<=2,catB<=2),1,0)

Then apply it like this:

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!

Hi,

Thanks for your answer ValtteriN ! The problem is that I have 150 categories so it will be very long for me to create one formula for each category.

Here is a measure that seems to work. Just replace Top2 with your actual table name.

Top 2 AB =
VAR top2x =
    TOPN (
        2,
        ADDCOLUMNS (
            ALLSELECTED ( Top2[product id] ),
            "cSales", CALCULATE ( SUM ( Top2[sales] ), ALL ( Top2[category 1] ) )
        ),
        [cSales], DESC
    )
VAR result =
    CALCULATE ( SUM ( Top2[sales] ), KEEPFILTERS ( top2x ) )
RETURN
    result
