To create a graphic layer based on coordinates from messages, use the command renderer/create_messages_layer:

svc=renderer/create_messages_layer&params={"lname":<text>,
					   "rname":<text>,
					   "itemId":<long>,
					   "timeFrom":<uint>,
					   "timeTo":<uint>,
					   "tripDetector":<bool>,
					   "trackColor":<text>,
					   "trackWidth":<int>,
					   "arrows":<bool>,
					   "points":<bool>,
					   "pointColor":<text>,
