Help analysing time intervals by minute of the day

[tlj]

Hi all,

I'm so new to Power BI that I don't even know if the following is easy or hard, but I know I'm stuck! I'm doing the edX course but I'm not ready for this.

I have a table of time intervals that cover a calendar year. Here's a sample.

I want to visualise how often each minute of the day appears in an interval, regardless of the date. So I'd like to make a graph with the minutes of the day from 00:00 to 23:59 along the X axis. There will be 1440 ticks (24 hours by 60 minutes.)

On the Y axis I want to show the number of intervals in which that minute of the day is included (ignoring date).

In SQL I could make a lookup table with all the minutes of the day, then populate it with the appropriate counts but I suspect there's a much slicker way of doing this in Power BI. Can anyone help please? Thanks.

Thanks, that nudged me forward. I'm stuck on the the hard bit now! 😀 

I'm trying to add a measure to my new Minute table to count the Intervals that contain the Minute. It's a head-scratcher... 🙂
