Apex Chart - Cluster per day of the week

Hello,

Not sure it’s possible, but I would like to use the waze sensor to estimate my daily commute time based on history.
The idea is to see the average value of my sensor on a 15-minute period but per day of the week, ie when is it best on Mondays, Tuesdays…
Is there any way to group data on a per day of the week base?
Thanks
