PROBLEM GROUPING HOUR BY 15 MIN

[aromero28]

I'm having several issues.

I need to be able to group by 15 or 30-minute intervals.

I have a table with a column "hour" with the exact hour and minute, and since there are many rows with different hours and minutes, I need to group them to make it easier to visualize.

I've been looking at old posts, but I can't get it to let me select the "hour" column.

Hi, @aromero28 

Thanks for @lbendlin reply. You can try the following MDX to solve the problem. 

= Table.AddColumn(#"Changed Type", "Custom", each Time.From(Number.RoundDown(Number.From(Time.From([Time]))*(24*60/15))/(24*60/15)))

Remember that time values are fractions. Multiply the time value by 96  (for 15 minute intervals), Round down, then divide by 96 again. That will give you the desired 15 minute buckets.
