Description yeray alonso 2013-11-20 10:33:41 EST 
Having a TFastLineSeries with only few points but with DrawAllPoints=false and DrawAllPointsStyle=daMinMax, the series seems to be drawn incorrectly.
Take a look at the following example and click on the checkbox to see how the series changes.
uses Series;
var fast1: TFastLineSeries;
procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;
  fast1:=Chart1.AddSeries(TFastLineSeries) as TFastLineSeries;
  fast1.FillSampleValues(25);
  fast1.DrawAllPoints:=false;
  fast1.DrawAllPointsStyle:=daMinMax;
end;
procedure TForm1.CheckBox1Click(Sender: TObject);
begin
  fast1.DrawAllPoints:=CheckBox1.Checked;
end;
