    Hi, collis 

     

    You can try the following methods. Start by adding the index column to the Power query.

    Count =
CALCULATE ( COUNT ( 'Table'[Site] ),
    FILTER (
        ALLEXCEPT ('Table','Table'[Scheduled Start],'Table'[Scheduled End],'Table'[Site]),
        [Index] <= EARLIER ( 'Table'[Index] )
    )
)

    Is this the result you were expecting?

Hi,

Share data in a format that can be pasted in an MS Excel file.

    Hi,

    This M code works

    let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Grouped Rows" = Table.Group(Source, {"Scheduled Start", "Scheduled End", "Site"}, {{"Count", each Table.AddIndexColumn(_,"Index",1)}}),
    #"Expanded Count" = Table.ExpandTableColumn(#"Grouped Rows", "Count", {"Index"}, {"Index"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Expanded Count",{{"Scheduled Start", type datetime}, {"Scheduled End", type datetime}, {"Site", type text}, {"Index", Int64.Type}})
in
    #"Changed Type"

    Hope this helps.

      Thank you. So fast. This works well, but it deletes other columns. How would I keep other columns to be used for other charts?

        You are welcome.  In the Grouped Rows step, mention all the columns.
