How to add vertical and 45° lines in maps

By default you can only create lines in the map designer by linking two map objects. You can change the angle by moving the map objects accordingly. However this article might be of interest as well.

Hello, I know the connector feature, but I want to add static lines that do not follow object states.

I'm afraid to tell you that this is not possible by default.

ok, not by default, but is it possible as "How to add line and labels on a map" article https://helpdesk.paessler.com/en/support/solutions/articles/31053.

Thank you !
