Complex sorting in Line Chart

Hello Community,

I am humbly requesting for contribution on this complex sorting, 

MY CASE : I have a forecast and actual values for 24 hours of the day on three different product, I am representing the data point in a line chart at the hourly level as shown in the chart for each other day for different product . I am finding it difficult to sort daily asc and hourly asc.

I added a slicer just to have just one product in the view at a time , the sortiing is still not right.

the Start time HE was created based on the logic below date and hour for the Axis. 

Starttime HE = (CONCATENATE(CONCATENATE(Hourly_Error_compare[date]," "),Hourly_Error_compare[hour_num]))

Current output 

Expected output

Thank you.
