How to calc teechart positions?

Hi all!
I'm using a teechart (v4.04 standard with Delphi 7) in the following way:

procedure TXyz.DisplayNewStatistics(data: Array Of Integer);
begin
  for i := low(Data) To high(Data) Do
       MyChart.Series[0].Add(Data[i], IntToStr(i+1), clTeeColor);
...
  // now check if marks are overlapping ...

  for i := 0 To Series[0].Marks.Count-1 Do Begin
    // NEVER reaches here
  end;
end;

The list of Marks is empty. Placing the code in OnAfterDraw is no
option too (the mark positions are present at that time) because they are
already drawn then and their position cannot be changed without a flicker
(same as with MyChart.Update in the methode above).

So how can I force the series to make its calculations without drawing
it's contents?

TIA
