One type of the TCHART are tracing point, you draw a line, then stipple a, and will point set is ok before

Then in some Series MouseEnter incident, X:=DotSeries. GetCursorValueIndex; Method to get the X coordinate
Y:=DotSeries YValue [X]; Method Y
Set the DotSeries. Parent. Hint:=IntToStr (X) + IntToStr (Y);
