How to divide a column by its length

[Anonymous]

I need to create a Cumulative Distribution Plot in Power BI without knowing the number of rows the data contains. I followed the steps in this tutorial https://www.youtube.com/watch?v=oyo8OwTMM38&t=312s, but he knows that his data contains 5000 rows. How can I add a "Frequency" column that contains Index/length(Index)?

Hi @Anonymous ,

In dax you can use countrows(table) to get the rows number in your table. then you can creat a calculated column:

Frequency = Table[index]/COUNTROWS(Table)

In power query you can use the following :

 = Table.AddColumn(last step name,
    "Frequency",
    each [Index]/Table.RowCount(last step name)
)

In Power Query , List.Max(#"Added Index"[Index])   will give you the number of rows.  #"Added Index" is the name of the previous step
