Description yeray alonso 2013-11-20 10:02:51 EST 
Having some points very near in XValue (in comparison with the other points proximity) the smoothed seems to give an strange behaviour:
uses Series, TeeSpline;

procedure TForm1.FormCreate(Sender: TObject);
var Series1, Series2: TLineSeries;
 TeeFunction1: TSmoothingFunction;
begin
 Chart1.View3D:=false;

 Series1:=Chart1.AddSeries(TLineSeries.Create(self)) as TLineSeries;
 Series1.AddXY(0,100);
 Series1.AddXY(100,130);
 Series1.AddXY(100.25,105);
 Series1.AddXY(200,155);

 TeeFunction1:= TSmoothingFunction.Create(self);
 Series2:=Chart1.AddSeries(TLineSeries.Create(self)) as TLineSeries;
 Series2.SetFunction(TeeFunction1);
 Series2.DataSource:=Series1;
end;
