Creating a new column in a visual that is the difference between the counts of two existing columns
I have a visual that is a matrix.
Col 3 is a count and Col 5 is a count.
I want to create a column that is the difference between Col 3 and Col 5.
I can't seem to find anything on creating an additional column with a formula inside a visual.
Thanks for the reply from Ritaf1983 and speedramps , please allow me to provide another insight:
Hi, chdcfs
Thanks for reaching out to the Microsoft fabric community forum.Regarding the issue you raised, my solution is as follows:
1.Assuming your data structure is as follows:
2.Here is the original visualization in the matrix:
3.You can try processing it using the following M language:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUXLOz1EwVorVoZxnioXnhKISO8+UIM8ZRR92nil+XiwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}), #"Grouped Rows" = Table.Group(#"Changed Type", {"Column1", "Column2"}, {{"Count", each Table.RowCount(_), Int64.Type}}), #"Pivoted Column" = Table.Pivot(#"Grouped Rows", List.Distinct(#"Grouped Rows"[Column2]), "Column2", "Count"), #"Added Custom" = Table.AddColumn(#"Pivoted Column", "DIFF", each [Col 3]-[Col 5]), #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"DIFF", Int64.Type}}), #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type1", {"Column1"}, "Attribute", "Value") in #"Unpivoted Columns"4.Here's my final result, which I hope meets your requirements.
Can you share sample data and sample output in tabular format if I am misunderstanding? Or a sample pbix after removing sensitive data. We can better understand the problem and help you.When uploading a file, please be careful to delete sensitive information.

Please find the attached pbix relevant to the case.

Try this ..
U days = CALCULATE( DISTINCTCOUNT('Calendar'[Day name]), CONTAINSSTRING('Calendar'[Day name] , "U") )S days = CALCULATE( DISTINCTCOUNT('Calendar'[Day name]), CONTAINSSTRING('Calendar'[Day name] , "S") )Difference = [U days] - [S days]Please click the [accept as solution] and the thumbs up button. Thank you
Hi speedramps
If I understood you correctly you are talking about visual calculation.
Which is work as a feature that allows us to make calculations based on visual.Please take a look at the linked video:

if it is something else
please provide some raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It would be helpful to find out the solution. You can refer the following link to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
