How can I create a line chart with duration calculations?

[Anonymous]

I have these measures:

Total_ACW = FORMAT(('All_NICE_Data'[Total_Handle_Time] - 'All_NICE_Data'[Total_Talk_Time]),"HH:MM:SS")

Total_Handle_Time = FORMAT(SUM(All_NICE_Data[Handle Time]),"HH:MM:SS")

Total_Talk_Time = FORMAT(SUM(All_NICE_Data[Talk Time]),"HH:MM:SS")

I want to be able to use any of these in a line chart to track calculations by day, week, or month in a line chart.  Power BI will not allow me to use them.

This is call center data and we need to be able to see these stats, what can I do to make this work better?

Hi @Anonymous ,

I think the challenge you're facing stems from the fact that the FORMAT function converts your measures into text strings, which cannot be directly used in line charts as they require numeric values to plot the data points.

You can change your DAX codes.

Total_ACW_Seconds = SUM('All_NICE_Data'[Total_Handle_Time]) - SUM('All_NICE_Data'[Total_Talk_Time])
Total_Handle_Time_Seconds = SUM('All_NICE_Data'[Handle Time])
Total_Talk_Time_Seconds = SUM('All_NICE_Data'[Talk Time])

Then you can use it in the line chart and you can change the format as you like.

Total_ACW_HH_MM_SS = 
VAR TotalSeconds = [Total_ACW]
RETURN FORMAT(TotalSeconds / 86400, "HH:MM:SS")
