Thanks! Another slightly odd thing that this test showed me is that in 3D mode the line segment between two points can be hovered over, but in 2D mode only the points can be hovered over. Is this intentional? Can line hovering be added for 2D, or made optional? Actually, an idea that would make hove...

Thank you for your reply. I am using v2017.22.170619, in C++ Builder 10.2.1. It looks like the problem arises because the bottom axis is inverted. The code below shows this in 2D; 3D behavior is even more bizarre-looking. It appears that nobody implemented counting backwards for hovering. TForm1::TF...

I get strange hovering behavior with a simple TLineSeries in VCL. In this example, my cursor is over the third point in the line, which is highlighted correctly, but only the first segment (connection between two points) is highlighted. The highlighted segment is always one behind the point being ho...
