Split timeline scheduler calendar

i need to split timeline view scheduler every 4 hours add marked line, please check sketch :

the scheduler does not support such splitting of the calendar area. But you can add vertical markers to the needed times either by using css templates:
docs.dhtmlx.com/scheduler/api__s … plate.html
docs.dhtmlx.com/scheduler/api__s … plate.html

Or via marked timespan api docs.dhtmlx.com/scheduler/limits … rtaindates
There is a similar example in this article docs.dhtmlx.com/scheduler/custom … scaleunits
