I need to create a line chart that has the ability to have a dot(or similar) follow the mouse cursor along a line chart, and when the user clicks, I can get the closest point to the location of the dot.
I did see this post, however it is old, and I cannot figure out how to implement the code given in CrossHairUI.java.

If someone can implement the solution from the above link, or help with a new solution, I would be very grateful!
