Index depending on column value

Hi,

 

I have this situation:

 

robertosangi_0-1646996937440.png

I created a conditional column that indexed my value. My problem is that I want this count restart depends on the week value and more i want to index my values depends on "Count" column. 

So i want to create a sort of rank of the week per each value of the "Codice Unità Territoriale" column.

 

How I can do that?

Thank you

From your table

serpiva64_1-1647246466451.png

you group rows by week and by count (in order to manage situation of parity)

serpiva64_2-1647246582672.png

hten you group by week

serpiva64_3-1647246624411.png

then you order descending your column count inside your groups

serpiva64_4-1647246731096.png

at this point you add and index column

serpiva64_5-1647246782174.png

at this point you first expand Custom

serpiva64_6-1647246870837.png

you obtain this

serpiva64_7-1647246912956.png

Finally you expand AllRows.1 

serpiva64_8-1647246951094.png

remove unnecessary column and that's done

Hi,

From this:

serpiva64_0-1647002622934.png

you canobtain this

serpiva64_1-1647002651350.png

applying these steps:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Vc45DoAwDETRu7hOwUSsZ4ko2EFiuX8H2E4xRYqn2NZPSQYJEr9XSh+SjK5WNbmicXY2qoUW1zzaKTenac+fhfLgs2dmrbzo7u2CzT7OSvW3g9pB7eB2UDuoHdwOage3g9vB7aB2cDusvX8B", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [CoUnTerr = _t, Week = _t, Count = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"CoUnTerr", type text}, {"Week", Int64.Type}, {"Count", Int64.Type}}),
#"Grouped Rows1" = Table.Group(#"Changed Type", {"Week", "Count"}, {{"AllRows", each _, type table [CoUnTerr=nullable text, Week=nullable number, Count=nullable number]}}),
#"Grouped Rows" = Table.Group(#"Grouped Rows1", {"Week"}, {{"AllRows", each _, type table [CoUnTerr=nullable text, Week=nullable number, Count=nullable number]}}),
#"Added Custom1" = Table.AddColumn(#"Grouped Rows", "Custom.1", each Table.Sort([AllRows],{{"Count", Order.Descending}})),
#"Added Custom" = Table.AddColumn(#"Added Custom1", "Custom", each Table.AddIndexColumn([Custom.1],"Index",1)),
#"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"AllRows", "Index"}, {"AllRows.1", "Index"}),
#"Expanded AllRows.1" = Table.ExpandTableColumn(#"Expanded Custom", "AllRows.1", {"Count"}, {"Count.1"}),
#"Removed Columns" = Table.RemoveColumns(#"Expanded AllRows.1",{"AllRows", "Custom.1"})
in
#"Removed Columns"

Hi @serpiva64 

Could you please write the steps without code? Is not well understandable but seems work.

 

Thanks

Hi  @serpiva64 I reached this step:

robertosangi_2-1647249332270.png

 

but expanding i obtained:

robertosangi_3-1647249363419.png



I think I missed something but i'm reaching the goal

 

Sorry i forgot to expand one column. You can do it in

serpiva64_0-1647018997071.png

and this is the final result

serpiva64_1-1647019030913.png

 

 

@serpiva64 just to close the question. 

I want to represent this in table. I wanted to insert the data you found in such way:

robertosangi_0-1647252045947.png

 

 

 

How can I do that in a table?
Thanks

Hi,

You can achieve something like this from your previous 

serpiva64_0-1647257644434.png

Add acolumn with W-1

serpiva64_1-1647257714203.png

Merge your query on itself

serpiva64_2-1647257772371.png

Expand

serpiva64_3-1647257794998.png

Change type then add difference column

serpiva64_4-1647257839165.png

change type

then you can create your matrix
