Description yeray alonso 2020-09-28 07:37:20 EDT 
Here a simple example:

procedure TForm1.AnnotationCallout;
var i: Integer;
    s: TPoint3DSeries;
begin
  Chart1.View3D:=True;

  s:=TPoint3DSeries(Chart1.AddSeries(TPoint3DSeries));
  with s do
  begin
    for i:=0 to 9 do
      AddXYZ(i, i, 5);

    Pointer.Size:=2;
    LinePen.Hide;
  end;

  Chart1.Draw;

  with TAnnotationTool(Chart1.Tools.Add(TAnnotationTool)) do
  begin
    Text:='Annotation here';
    With Callout do
    begin
      Draw3D:=True;
      Arrow.Visible:=True;
      Arrow.Color:=clRed;

      XPosition:=s.CalcXPos(5);
      YPosition:=s.CalcYPos(5);
      ZPosition:=s.CalcZPos(5);
    end;
  end;
end;
