Calculating average value for a day of a month comparing to other value

PbiCeo — Wed, 02 Sep 2020 14:08:14 GMT

Hello everyone,

I want to calcutalte average value for a day of a month comparing to other value with Measure:

Measure1 =
VAR tm = CALCULATE(SUM('table'[data1]), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))
return
DIVIDE('tm', 'table'[NumberofDays], 0)

Measure2 =
VAR tm = CALCULATE(SUM('table'[data2]), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))
return
DIVIDE('tm', 'table'[NumberofDays], 0)

MeasureResult = DIVIDE('table'[Mesaure1], 'table'[Measure2], 0)

But MeasureResult returns the all same value on Table visual.

How to get value row by row?
Thanks in advance,

Vladi

PbiCeo - This looks like a measure aggregation problem. See my blog article about that here: https://community.powerbi.com/t5/Community-Blog/Design-Pattern-Groups-and-Super-Groups/ba-p/138149

The pattern is:
MinScoreMeasure = MINX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
MaxScoreMeasure = MAXX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
AvgScoreMeasure = AVERAGEX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
etc.

2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

Thanks for your reply.

Is there any way to do with minimum change from my code?
Thanks,

PbiCeo , your NumberofDays measure should be like

NumberofDays =CALCULATE(distinctcount('table'[Date]), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))
or
NumberofDays =CALCULATE(distinctcount('calendar'[date]), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))

You can this measure like

MeasureResult =

CALCULATE(DIVIDE(SUM('table'[data1]), SUM('table'[data2]), 0), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))

Hello amitchandak ,

Thank you for your reply.

Although I can get correct value from these 2 Measure.

Measure1 =
VAR tm = CALCULATE(SUM('table'[data1]), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))
return
DIVIDE('tm', 'table'[NumberofDays], 0)

Measure2 =
VAR tm = CALCULATE(SUM('table'[data2]), FILTER(ALL('calendar'), 'calendar'[date] <= 'calendar'[date]))
return
DIVIDE('tm', 'table'[NumberofDays], 0)

But when I try to compare them, I get all same value on Table visual.
MeasureResult = DIVIDE('table'[Mesaure1], 'table'[Measure2], 0)

Almost there, please give me advice?

Thank you,

PbiCeo - We should probably back-up. Post sample data and expected result. It has proven to be the absolute quickest way of resolving problems for all of recorded time on these forums.
