Matrix - Adding values from same excel row

[ALZEnith]

Hi,

I have a simple table (below).

I need to add a column to the Matrix which substract the "Red" Type 24/20 for September 2022 with the "Red" Type 24/20 for June 2022. Ideally, it would look something like the below:

How would you go about doing this in DAX? The issue I have is that I am trying to pick and combine/substract two values from the same column.

Any help would be appreciated.

Thanks

Alexis

Hi @ALZEnith ,

According to your description, here are my steps you can follow as a solution.

(1)Click "Transform data" to enter the power query editor, click "Advanced Editor", and paste the following code.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("dc07CoBADATQu2wtaD6jsbXwALaynRaClej93ayCKFhNBuaRcQzDPIUicMVctiWlkxoAnlbBOyux9347lj3E4kXqixDniaqBvSdDL9Ktx/x5QyySt9bWKUVhza+5/4jAsoH6lhQkj4kn", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Type = _t, Date = _t, #"24/20" = _t, #"24/30" = _t, #"24/40" = _t, #"Food type" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Type", type text}, {"Date", type date}, {"24/20", Int64.Type}, {"24/30", Int64.Type}, {"24/40", Int64.Type}, {"Food type", type text}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Type", "Date", "Food type"}, "Attribute", "Value"),
    #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Columns",{{"Attribute", "Column Name"}})
in
    #"Renamed Columns"

(2)Click "Apply and Close" to create a new calculated column in Desktop.

 Column = FORMAT( [Date] ,"mmm") & " " & [Type]

(3)Then we can create a new table 2.

Table 2 = UNION( VALUES('Table'[Column]) ,{"Red Difference"})

(4)Then we can create a measure.

Measure = var _coloum = SELECTEDVALUE('Table 2'[Column])

var _Sept_red =SUMX(FILTER('Table' , MONTH('Table'[Date]) = 9 && 'Table'[Type]="Red") , [Value])

var _June_red =SUMX(FILTER('Table' , MONTH('Table'[Date]) = 6 && 'Table'[Type]="Red") , [Value])

return

IF(_coloum ="Red Difference" ,_Sept_red-_June_red ,CALCULATE(SUM('Table'[Value]), TREATAS(VALUES('Table 2'[Column]) , 'Table'[Column] )))

(5)Finally, a matrix visual is created, and the result is shown in the following image.
