Create new measure to get Average

[siva3012]

Hi, I have a table which contains Date, CustomerName, Price, month, & weekday.

I have created measure using the DAX, Day 1 = CALCULATE(sum(Actual[Price]),FILTER('Actual','Actual'[Day]=1))

similarly for all days. If i select 3 months at a time i am getting the total values, as shown in the fig

My query is  I need to get an average value's if i select 2 or 3 months in the slicer.  Anyone has an idea how to solve this ?

Hi @siva3012,

Create an extra measure like:

Count month selected = DISTINCTCOUNT(Actual[Month])

Modify the measure for Day 1 as below:

Day 1 = CALCULATE(sum(Actual[Price]),FILTER('Actual','Actual'[Day]=1))/[Count month selected]

Result.

Best regards,

@v-yulgu-msft : Is it possible to draw an average line for those data which is shown in the graph ? Like this

@v-yulgu-msft : Hi, There is an small eror in the solution. If we select 2 Months data Jan & Feb in slicer. Jan has 31 days and Feb has 28 days. The average is been calaculated wrongly for Jan 29, 30 & 31. 

 Do you have any idea over this ?

I have solved this issue,

Day 1 = CALCULATE(sum(Actual[Price]),FILTER('Actual','Actual'[Day]=1))/(CALCULATE([Count month selected],Actual[Day]=1))
