Description yeray alonso 2018-05-11 02:49:58 EDT 
Having two stacked TAreaSeries, when you move the mouse over the area, PointInArea calls GetOriginPos(Index-1) to calculate the rectangle, but this function is called for Index=0 so it can give an exception.

Sample code:

  Chart1.View3D:=False;
  Chart1.Legend.Hide;
  for i:=0 to 1 do
    with Chart1.AddSeries(TAreaSeries) as TAreaSeries do
    begin
      MultiArea:=maStacked;
      FillSampleValues(5);
    end;
