## Compare data rows so that total calculated is difference of the row in value and in percentage

hi

I am comparing 2 years of data

I have a matrix and have months across the Top and years down the side.  The matrix as standard will total each column.

How can make the matrix like the sample attached where it subtracts one value from another and displays difference and also the difference percentage.

Hi @mecr123

Open Edit queries,

Create a new blank query, write code as below in Advanced editor

```let
Source = Table1,
//add columns
#"Inserted Year" = Table.AddColumn(Source, "Year", each Date.Year([date]), Int64.Type),
#"Inserted Month" = Table.AddColumn(#"Inserted Year", "Month", each Date.Month([date]), Int64.Type),
#"Inserted Month Name" = Table.AddColumn(#"Inserted Month", "Month Name", each Text.Start(Date.MonthName([date]),3), type text),
#"Removed Columns" = Table.RemoveColumns(#"Inserted Month Name",{"date"}),
//filter table
#"2017 TABLE"=Table.SelectRows(#"Removed Columns", each ([Year] = 2017)),
#"2018 TABLE"=Table.SelectRows(#"Removed Columns", each ([Year] = 2018)),
//merge queries
#"Merged Queries" = Table.NestedJoin(#"2017 TABLE", {"Month Name"}, #"2018 TABLE", {"Month Name"}, "new", JoinKind.LeftOuter),
#"Expanded new" = Table.ExpandTableColumn(#"Merged Queries", "new", {"value"}, {"new.value"}),
//Add diff
#"Added Custom" = Table.AddColumn(#"Expanded new", "Diff", each [new.value]-[value]),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "Diff%", each ([new.value]-[value])/[value]),
//diff table
#"diff table"=Table.SelectColumns(#"Added Custom1",{"Year", "Month","Month Name", "Diff"}),
#"Renamed Columns1" = Table.RenameColumns(#"diff table",{{"Diff", "value"}}),
#"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns1",{{"Year", type text}}),
#"Replaced Value1" = Table.ReplaceValue(#"Changed Type1","2017","Diff",Replacer.ReplaceText,{"Year"}),
//diff% table
#"diff% table"=Table.SelectColumns(#"Added Custom1",{"Year", "Month","Month Name", "Diff%"}),
#"Renamed Columns2" = Table.RenameColumns(#"diff% table",{{"Diff%", "value"}}),
#"Changed Type2" = Table.TransformColumnTypes(#"Renamed Columns2",{{"Year", type text}}),
#"Replaced Value2" = Table.ReplaceValue(#"Changed Type2","2017","Diff%",Replacer.ReplaceText,{"Year"}),
//reorder columns
#"reorder1"=Table.ReorderColumns(#"2017 TABLE",{"Year", "Month", "Month Name", "value"}),
#"reorder2"=Table.ReorderColumns(#"2018 TABLE",{"Year", "Month", "Month Name", "value"}),
#"reorder3"=Table.ReorderColumns(#"Replaced Value1",{"Year", "Month", "Month Name", "value"}),
#"reorder4"=Table.ReorderColumns(#"Replaced Value2",{"Year", "Month", "Month Name", "value"}),
//append queries
#"Appended Query" = Table.Combine({#"reorder1", #"reorder2", #"reorder3",#"reorder4"})
in
#"Appended Query"
```

Close&&apply

Create a measure in “Query1” table

`Measure = IF(MAX(Query1[Year])="diff%",FORMAT(MAX(Query1[value]),"0.00%"),MAX(Query1[value]))`

Sort “month name” column by “month” column

Hi @mecr123

This would need some transformation for the data model.

Could you clear me if you table has only year 2018, 2019, or many years?

If there are many years in your table,

Do you want to display every two years and their difference by slicer?

Best Regards
Maggie

Hi Maggie

Yes I am only only going to load 2 years - 2018 & 2019.

Ideally I would like to display it as I have outlioned as I want to see all months and the comparisons.

thanks for your help

Michael
