If you know mouse cursor location in pixels you can use chart.HitTest(x,y) method to find chart element directly under this coordinate. You can also use Axis.PixelPositionToValue method to convert pixels to axis scale value. As soon as you know axis scale value you can find chart element closet to the position.
