Average Time in chart
Hi, I've just had a look at your pbix.
The Duration column won't chart properly because it doesn't have the correct datatype. It is set as Time which is not correct, it needs to be a decimal or whole number. That means the calculation of Duration needs to change. Use DATEDIFF and decide which units you want (HOURS, MINUTES or SECONDS).
You will then be able to chart Date against Average Duration. You might have to write a measure to alter the average calculation because powerbi will not throw away the line with 0 duration.
