Multiple Data Points on Same Day - HOW TO COUNT?

[GO-ASTROS]

Hello, I am new to Power BI and need help.  I am trying to use data points from a piece of equipment that give me multiple data points on the same day.  Example:  On today (5/2/2023), Equipment "A" may product three (3) values at different times (7:10:00am, 12:05:00pm, and 2:55:00pm).  I need help on how to let Power BI know I want it to include all three values on my line chart at the times specified.  Is this possible?  Or, should I just average all three results into one result on one day?  

I tried using Excel quick keys for Cntr+Shift+; to return time, but it always returns the hour and minutes, but seconds are alway "00", not sure why that is and would also like some help.

Change your source data to contain a DateTime field for the exact timestamp, or use a hierarchy with the Date and Time fields.
