How to Aggregate Temperature Column Per Hour Per Day

Ibrahim_shaik — Fri, 15 Mar 2024 05:56:46 GMT

Hi Power BI Community,

I have a date, time column in the time column i have 5 minute interval timestamp and a temp column which has temp value for every 5 minute timestamp.

I want to create a column in which i get the average temp value of the hour of the 5 minute intervals in an hour per day that is 24 values for a day.

Please give a solution.

I have used this DAX it gives me a blank column.

AverageTemperaturePerHour =

VAR CurrentDate = MAX('AmbTemp'[date])

VAR CurrentHour = HOUR(MAX('AmbTemp'[time]))

RETURN

CALCULATE(

AVERAGE('AmbTemp'[t_out]),

FILTER(

'AmbTemp',

'AmbTemp'[date] = CurrentDate &&

HOUR('AmbTemp'[time]) = CurrentHour

)

Please give a solution.

Hi, Ibrahim_shaik

May I ask if you have already solved this problem? On top of the DAX you wrote, just add an ALL.

Measure:

Expected = VAR CurrentDate = MAX('AmbTemp'[date]) VAR CurrentHour = HOUR(MAX('AmbTemp'[time])) RETURN CALCULATE( AVERAGE('AmbTemp'[t_out]), FILTER( ALL('AmbTemp'), SELECTEDVALUE('AmbTemp'[date]) = CurrentDate && HOUR('AmbTemp'[time]) = CurrentHour ) )
