Changing Average of Seconds in minutes and seconds - powerbi

Question

I have a table below:
I am trying to get the average of "someNumber" (which is number of seconds) per date and then convert that number into miutes and seconds.
So, I am drawing the graph below:
As you can see, I used the average filter and it calculated the average of "someNumber" per date. For instance, the average on 1st is 13. Now, how do I convert 13 into minutes and seconds so that I can display it as a tooltip?

Answer 1

Create a measure to get the average in seconds.
avg = AVERAGE(Table[SomeNumber])
Then create a measure for the tooltip lets call it Time, this helpful measure was created by #konstantinos and #smoupre in the Power BI community blog.
Time =
VAR Duration = [avg] // Here use the average measure created before
VAR Hours =
INT ( Duration / 3600)
VAR Minutes =
INT ( MOD( Duration - ( Hours * 3600 ),3600 ) / 60)
VAR Seconds =
ROUNDUP(MOD ( MOD( Duration - ( Hours * 3600 ),3600 ), 60 ),0)
VAR H =
IF ( LEN ( Hours ) = 1,
CONCATENATE ( "0", Hours ),
CONCATENATE ( "", Hours )
)
VAR M =
IF (
LEN ( Minutes ) = 1,
CONCATENATE ( "0", Minutes ),
CONCATENATE ( "", Minutes )
)
VAR S =
IF (
LEN ( Seconds ) = 1,
CONCATENATE ( "0", Seconds ),
CONCATENATE ( "", Seconds )
)
RETURN
CONCATENATE ( M, CONCATENATE ( ":", S ) )
Now use the [Time] measure as tooltip in your chart
Hope it helps.
