Hi José,

As the mark has been moved, it has to be recalculated if the chart changes. You could call a method like following when the legend visibility changes:

Code: Select all

procedure TForm1.RecalcMarks;
var i, tmpx, dx: Integer;
    pos: TSeriesMarkPosition;
begin
  for i:=0 to Chart1[0].Count-1 do
  begin
    tmpx:=Chart1[0].CalcXPos(i) + (Chart1[0] as TBarSeries).BarWidth div 2;

    pos:=Chart1[0].Marks.Positions[i];
    if (tmpx <> pos.ArrowFrom.X) then
    begin
      dx:=pos.ArrowTo.X - pos.ArrowFrom.X;
      pos.ArrowFrom.X:=tmpx;
      pos.ArrowTo.X:=tmpx + dx;
      pos.LeftTop.X:=tmpx + dx - (pos.Width div 2);
    end;
  end;

  Chart1.Repaint;
end;
