Hourly range covering two consecutive days

Yes, please take a look at this:

Let me know if this is not what you are looking for.

I would like to use the scheduler component because it seems more suitable for what I have to do.
I would like to have the members of my staff on the x axis and on the y axis so that I can organize work shifts.
this work will be done only once but it must allow in the future to be able to reorganize the shifts

OK, thanks for the update. In the Scheduler, there are two ways to achieve that:

1. You can define the timeline manually by adding individual cells:
https://doc.daypilot.org/scheduler/timeline/

2. You can use an hourly scale and remove the selected timeline cells (hours) using onIncludeTimeCell event handler:
https://doc.daypilot.org/scheduler/hiding-time-columns/

This will let you display custom hours, e.g. from 20:00 to 4:00 the next day.
