Difference between values in same column

[Anonymous]

Hi

I'm trying to display the difference between values in a table. I have searched around and viewed PREVIOUSMONTH function etc but the way my data is structured there are gaps in dates between emails being sent out - so it needs to pick up the last known send. See screengrab of what I am after (desired output column):

I have email statistics data and have created a measure to produce the unique clicks of each email. I can drop into a table and show when the email was sent, the name and the click rate using the measure. However, I need to show the change in click rate consecutively as each email goes out as and when.

Is there DAX code that will support this?

Thanks

Hi @Anonymous ,

You need create an Index column in Query Editor and create a measure with the formula below.

Measure =
VAR a =
    CALCULATE (
        [click_reate],
        FILTER (
            ALLSELECTED ( 'Table1' ),
            'Table1'[Index]
                = MAX ( 'Table1'[Index] ) - 1
        )
    )
RETURN
    IF ( a = BLANK (), BLANK (), 'Table1'[click_reate] - a )

Here is the output.

Best Regards,
