Description yeray alonso 2013-11-20 10:33:18 EST 
Deppending on the Chart's width, the daMinMax DrawAllPointsStyle gives a strange result.
See the following example and resize the form to see how some "stairs" are drawn for the second series, while one would think it should be similar to the first series.
uses Series;
procedure TForm1.FormCreate(Sender: TObject);
var fast1, fast2: TFastLineSeries;
    cust1, cust2: TChartAxis;
    i: Integer;
begin
  Chart1.Align:=alClient;
  Self.Width:=820;
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;
  Chart1.MarginLeft:=7;
  Chart1.AllowPanning:=pmHorizontal;
  cust1:=TChartAxis.Create(Chart1);
  cust2:=TChartAxis.Create(Chart1);
  cust1.EndPosition:=48;
  cust2.StartPosition:=52;
  fast1:=Chart1.AddSeries(TFastLineSeries) as TFastLineSeries;
  fast2:=Chart1.AddSeries(TFastLineSeries) as TFastLineSeries;
  for i:=1 to 1440 do
  begin
    fast1.Add(100 * (i mod 2));
    fast2.Add(100 * (i mod 2));
  end;
  fast1.CustomVertAxis:=cust1;
  fast2.CustomVertAxis:=cust2;
  fast2.DrawAllPoints:=false;
  fast2.DrawAllPointsStyle:=daMinMax;
end;
