I have a question and urgently ask for your help!!!
The following problem:
I have four data columns which I can filter (e.g. by month). In Power BI I have calculated the average per column using the AVERAGE function.
Mean V1=AVERAGE([Value1] -> New Measure: fx Mean V1
This for all 4 Values, meaning I get 4 functions (each the average of these individual columns).
So far so good.
Now I want to calculate the average over these four columns. Unfortunately, I cannot have AVERAGE calculated using functions (fx). Therefore I simply summed up the functions (fx) with CALCULATE and divided by 4
=CALCULATE([fx average V1]+[fx average V2]+[fx average V3]+[fx average V4])/4
This only works if all results of the functions (fx) contain values. If a function (fx) gives no values, the mean value is calculated incorrectly. What can I do now to get a dynamic divisor?
Is it somehow possible to generate again a mean value from functions?
