Need help with DAX.
I have a table from a Call Center company, where people call and ask for support.
I have the date and full time (including seconds) when a call starts, ends, and total time on hold (waiting for an available attendant).
My dashbard is shown in periods of 30 minutes.
I need to know, in each 30 minutes, what is the maximum quantity of calls on hold.
Lets say this company only have 3 lines to receive calls.
In the image below, showing a full 30 minutes period, rows 1, 2 and 3 are active calls.
Row 4 starts on hold (dashed line) and the call is active only when row 2 ends.
Row 5 starts on hold (dashed line) and the call is active only when row 1 ends.
Row 6 starts on hold (dashed line) and the call is active only when row 3 ends.
Column A is only active calls.
Column B is 1 call on hold.
Column C is 2 calls on hold.
Column D is 3 calls on hold.
Column E is 2 call on hold.
Column F is 1 call on hold.
Column G is only active calls.
In this example, I need to show 3 as the maximum quantity of simultaneous calls on hold ( column D ).
It is not the distinct count of rows 4, 5 and 6.
How do I do this?
Take a look at these two Quick Measures as I think you want something like them.

thanks for the reply, but this don´t work.
it actually crashed my computer.
I think it is because of too many rows. more than 1,2 million.
I created a separated calendar table with all seconds available, and tried to run it on a table object, but then my computer crashed.
