Average score 7 days after the selected date

[Alina-R]

A beginner question 🙂

We have a recurring monthly event that we use the same survey for - SurveyMonkey connecte to PowerBi.

We usually get responses within 5-6 days after the event. On the right there is a list of event dates, from event plan table. I need help showing average score for the event on selected date - so I'm thinking a measure that will display average of score for 7 days following selected date.

@Alina-R , You need have date/table of date(no timestamp)  . it should not join with event table

then you can have measure like this displayed with event date or joined date table 

//Date1 is independent Date table, Date is joined with Table
new measure =
var _max = maxx(allselected(Date1),Date1[Date])
var _min = _max -5
return
calculate( Average(Event[Score]), filter('Date', 'Date'[Date] >=_min && 'Date'[Date] <=_max))

Hi Amit,

Thanks for your reply. Unfortunately I can't quite get it to work. There is no error in measure itself, but it won't display:

"Communication plan" has date and is joined with Event table.

Date1 is independent date table.

What am I doing wrong?
