Calculate an average from a Sum by Month

Hi Guys, 

 

I want the average from a time Period.

In one Table i have 2 Rows like this:  

 

Date:                  Values:                

01.01.2016        100

01.01.2016        50

01.01.2016        10

01.02.2016        50

01.02.2016        50

01.02.2016        20

 

 

If i creat visuals with average i only get the full average of all data ( 46,6666) 

but i need it per Month  '
average  01/2016 = 53,33

              02/2016 = 40

I tryed a lot of things with the little DAX i know but nothing worked out correctly. 

 

thank you in advance

Re: Calculate an average from a Sum by Month

Hi Mertsch,

 

I have tested it on my local environment, you can add calculated column to display the month name using the DAX below
Month = MONTH(MonthAverage[Date])

And then create a measure
MeasureAverage = SUM(MonthAverage[Total])/DISTINCTCOUNT(MonthAverage[Month])

Re: Calculate an average from a Sum by Month

Re: Calculate an average from a Sum by Month

Looks like you want to get the average by Summing the amount and dividing it by the number of months/distinct dates rather than dividing by the number of rows. 

This might help, write following DAX measures:

Amount=SUM([Values])

NumOfDistinctDates=DISTINCTCOUNT([Date])

Avg=DIVIDE([Amount],[NumOfDistinctDates])

Re: Calculate an average from a Sum by Month

Try creating a calculated column like:

 

Month = MONTH([Date])

Then add your Average measure and Month to a table.

Re: Calculate an average from a Sum by Month

well it wokrs for the full tabel but if i used filters it dont work for it. 

 

( 140 is correct for all data )

But after using Filters it will be still 140.  it need to be 60 in that case

There must be a other way to have it more flexible with using filters

The data need to be calculated acording to the used filters and visual in front end.

 

May it works with GROUPBY Month Dates?! But i dont get the DAX work

= GROUPBY (Tabelle1;Tabelle1[Month];“TEST2”;SUM(CURRENTGROUP();Tabelle1[Total]))

Re: Calculate an average from a Sum by Month

Hi,

What if we want to use this measure with a date drill down, how would it work?

Re: Calculate an average from a Sum by Month

Hi,

I am a beginner in Power BI. I want to arrive at % of surgeries performed by each doctor for the month. i. e. total surgeries by a doctor in a month DIVIDED BY total surgeries in the month. 

 

Data.png

 

When I used the solution in a measure as "MonthlySurgeries = sum(tblReportPaed[Surgeries])/DISTINCTCOUNT(tblReportPaed[MonthNumber])" it generates an error at the bottom of the screen which reads as "TABLE: tblReportPaed (92 Rows) COLUMN: Measure (0 distinct values)".

Where am I going wrong?

 

Appreciate in advance.

Re: Calculate an average from a Sum by Month

This does not work if the data covers a period longer than a year as multiples will appear over multiple years, is there another way?
