DAX _25 - Top5Bottom5 06182023.pbix (710.6 KB)

Solved in 2 different ways

DAX Codes:

1st way: Making use of Top 5 /Bottom 5 as radio button

Range Table:{“Ranges” , “List” }, { “Top 5”, “Bottom 5”}
Rankings =
VAR _top = RANKX( ALL( Customers[Customer Names] ), [Total Sales], ,DESC)
Var _bottom = RANKX( ALL( Customers[Customer Names] ), [Total Sales] , ,ASC )
Var _result = IF( SELECTEDVALUE( Range[Ranges] ) = “Top 5”, _top, _bottom )

RETURN
    IF( _result <= 5 , [Total Sales] )

2nd Way
Top 5 =
CALCULATE( [Total Sales] ,
FILTER( VALUES(Customers[Customer Names] ),
IF( RANKX( ALL( Customers[Customer Names] ), [Total Sales] ) <= 5,
[Total Sales] , BLANK() ) ) )

Bottom 5 =
CALCULATE( [Total Sales],
FILTER( VALUES(Customers[Customer Names] ),
IF( RANKX( ALL( Customers[Customer Names] ), [Total Sales], ,ASC ) <= 5,
[Total Sales] , BLANK() ) ) )

Selected 5 =
SELECTEDVALUE(‘Table’[Top/Bottom])

TOP_BOTTOM Sales =

VAR RankTop = RANKX(ALL(Customers[Customer Names]),[Total Sales],DESC)

var RankBottom = RANKX(ALL(Customers[Customer Names]),[Total Sales],ASC)

var TopSales = if(RankTop <=5, [Total Sales], BLANK())

var BottomSales = IF(RankBottom >1 && RankBottom <= 106,[Total Sales],BLANK())

VAR Solution =

SWITCH(TRUE(),

[Selected 5] = “Top_5”, TopSales,

[Selected 5] = “Bottom_5”, BottomSales,

BLANK())

return
