## Counting Days in a column

Hey all,

its really hard to explain, so I'll try to show you what I want within the following table. What I want is a formula for the column "Number of Days".

As the table doesn't has values for every date, the formula for "Number of Days" has to refer to a calendar-table (I guess...), which is already created. Otherwise, you could say, that the date of the first apperance of a product could get the day number 1, but then I don't know how to do count the days that are missing in this table.

 Vol Date Product Number of Days 1 24.07.2022 A 1 2 24.07.2022 A 1 3 25.07.2022 A 2 2 26.07.2022 A 3 2 28.07.2022 A 5 1 29.07.2022 B 1

I hope this is understandable.

Thank you very much in advance!

Hi, @phjz

You can't apply a measure to the x-axis of line chart.

You need to convert your original measure formula to calculated column formula.

``````Column_Number of days =
VAR basedate =
CALCULATE ( MIN ( Table1[Date] ), ALLEXCEPT ( Table1, Table1[Product] ) )
RETURN
DATEDIFF ( basedate, Table1[Date], DAY ) + 1
``````

hello @phjz ,

``````Number of days =
VAR basedate = CALCULATE(MIN(Table1[Date]),ALLEXCEPT(Table1,Table1[Product]))
return
DATEDIFF(basedate,SELECTEDVALUE(Table1[Date]),DAY) +1``````

That does work really good - thank you so much!

There is one last problem with this: I want to compare Product A and B using a line diagram, but I can't put the measure on the x-axis. When I try to type the formula in the field for a new column, it doesn't work. Do you have an idea for this?
