What I am trying to do is make my own tooltip when you selected a point on a chart. The problem I am having is with the placement of the container. My screen is set to maximize on open and the components are set to relative. For some reason the event.source.x and event.source.y are incorrect when I test it out in the application. The coordinates are correct when I am in the designer.
I was thinking if I could get the mouse coordinates relative to the entire window that maybe they would be correct, but do not know how to do this. How should I go about getting accurate coordinates for the placement of the container without changing from relative layout?
