Count of days based on filter for average

[Anonymous]

Hi, i am a newbie in power bi so pardon my ignorance 🙂

I have application wise traffic data since 24-Feb-2020 till 08-Apr-2020 (45 days). An application has sub application so for single day multiple rows per application is possible.

I just want to get daily average traffic of each application based on the selected days in filter. But i am unable to get the days count correctly.

I applied month filter for Apr, there are 8 dates data for April. It is possible that some application might have only 5 days data for April. So i want to return count of days per each application.

I used following formula, but it is returning me 45 for each application, though i've applied Apr filter.

Measure =

var start_Date=FIRSTDATE(ALLSELECTED('App'[Date]))

var end_Date=LASTDATE(ALLSELECTED('App'[Date]))

return

CALCULATE(DATEDIFF(start_Date, end_Date, DAY))

Once i get the correct count of day, I will divide it with sum of traffic to get the average.

any help would be appreciated.

The formula and relation has some problem

distinct date use
distinctcount('App'[Date])

It looks like a relationship is not setup correctly.
