using hours on X-Axys, resources on Y-axys, and a second metric on Y-asyx

I'm not sure what exactly you are trying to achieve but here are the related options:

1. You can specify the vertical position of an event inside a row manually:
https://code.daypilot.org/91222/javascript-scheduler-event-placement-strategies

2. You can split the row to display multiple resources (which you can use to display hours):
https://doc.daypilot.org/scheduler/split-resources/

3. You can set custom height for each event in pixels (using the "height" property):
https://api.daypilot.org/daypilot-event-data/

Okay, I'll try to explain better.

I split the resources with split. So far so good.

Now, I need a given event to "cover" more than one resource, without increasing the row itself.

To do this, I tried to increase the height of the event, but in doing so, the line (resource) also increases, I need it to be the same size every time.

I need the event to "cover" the other resource lines, without increasing them.

Is there somewhere I can post an example? I think it will be clearer what I need.

Unfortunately, an event can't span multiple rows. The only option is to display such an event as multiple events, one per row.
