Average response time and callout duration

[Anonymous]

Hi,

I am new to Power BI and currently working on my 1st project.  I have got stuck on the last hurdle and can't seem to figure out how to resolve my issue.  I have imported a single excel spreadsheet into Power BI and want to make a simple table that takes data from 3 columns (response type has 3 options PRE, No Gas, Meter Fault) and give me the average reponse time and callout duration for each of the 3 response types - PRE, No gas and meter fault jobs.

As you can see it is listing every time per row rather than give me an average for each response type.  I tried AVERAGEX but it would only give me the option of a count total.

I would be really grateful if someone could point me in the right direction with this.

Thanks,

David

Hi @Anonymous ,

Sorry, Power BI does support duration formats now. 

Create your measure like so:

Response Time in Second Measure 2 = 
VAR Hours =
    TRUNC ( [DateDiffSeconds Measure]/3600 )
VAR Minutes =
    TRUNC ( ( [DateDiffSeconds Measure] - Hours * 3600 ) / 60 )
VAR Seconds = [DateDiffSeconds Measure]- Minutes * 60 - Hours * 3600
RETURN
Hours * 10000 + Minutes * 100 + Seconds

And then change the data format manually.

And then create visuals:

Hi @Anonymous ,

How about this?

If you want to create columns, try this:

DateDiffSeconds = DATEDIFF ( [Occurrent Time], [Response Time], SECOND )

Response Time in Second = 
VAR Hours =
    TRUNC ( [DateDiffSeconds] / 3600 )
VAR Minutes =
    TRUNC ( ( [DateDiffSeconds] - Hours * 3600 ) / 60 )
VAR Seconds = [DateDiffSeconds] - Minutes * 60 - Hours * 3600
VAR Result =
    Hours & ":"
        & FORMAT ( Minutes, "00" ) & ":"
        & FORMAT ( Seconds, "00" )
RETURN
    CONVERT ( Result, DATETIME )

Call out duration = 
VAR Avg_Seconds =
    CALCULATE (
        AVERAGEX ( 'Table', [DateDiffSeconds] ),
        ALLEXCEPT ( 'Table', 'Table'[Response Type] )
    )
VAR Hours =
    TRUNC ( Avg_Seconds / 3600 )
VAR Minutes =
    TRUNC ( ( Avg_Seconds - Hours * 3600 ) / 60 )
VAR Seconds = Avg_Seconds - Minutes * 60 - Hours * 3600
VAR Result =
    Hours & ":"
        & FORMAT ( Minutes, "00" ) & ":"
        & FORMAT ( Seconds, "00" )
RETURN
    CONVERT ( Result, DATETIME )

If you want to create measures, try this:

DateDiffSeconds Measure = DATEDIFF(MAX('Table'[Occurrent Time]),MAX('Table'[Response Time]),SECOND)

Response Time in Second Measure = 
VAR Hours =
    TRUNC ( [DateDiffSeconds Measure]/3600 )
VAR Minutes =
    TRUNC ( ( [DateDiffSeconds Measure] - Hours * 3600 ) / 60 )
VAR Seconds = [DateDiffSeconds Measure]- Minutes * 60 - Hours * 3600
VAR Result =
    Hours & ":"
        & FORMAT ( Minutes, "00" ) & ":"
        & FORMAT ( Seconds, "00" )
RETURN
    CONVERT ( Result, DATETIME )

Call out duration Measure =
VAR Avg_Seconds =
    CALCULATE (
        AVERAGEX ( 'Table', [DateDiffSeconds Measure] ),
        ALLEXCEPT ( 'Table', 'Table'[Response Type] )
    )
VAR Hours =
    TRUNC ( Avg_Seconds / 3600 )
VAR Minutes =
    TRUNC ( ( Avg_Seconds - Hours * 3600 ) / 60 )
VAR Seconds = Avg_Seconds - Minutes * 60 - Hours * 3600
VAR Result =
    Hours & ":"
        & FORMAT ( Minutes, "00" ) & ":"
        & FORMAT ( Seconds, "00" )
RETURN
    CONVERT ( Result, DATETIME )

Hi,

My end result would probably look something like this which I can then make some charts with the data.

Thanks,
David

Hi @Anonymous ,

Although the type of the measure is "DateTime", you could choose the display format as "Time". This has no effect on the results.

And for "make some charts with the data", data of "Time" type can't work the same as decimal number in a chart. For example, in a bar chart:

You could choose to put [DateDiffSeconds Measure] in Values field and [Response Time in Seconds Measure] in Tooltips field.

Hi,

Thanks very much for getting back to me.  Sorry about my late reply, I am only getting back to this now.  This is looking great although the reponse times and durations are showing as a date in the report rather than the times.  Thoughts?

Many Thanks,

David
