Description yeray alonso 2013-11-20 10:03:16 EST 
When you create a TBollingerFunction, an internal TFastLineSeries (IOther) is created because the Bollinger consists in two lines, one above and one below the source. So we have the series linked to the function and the internal IOther series, but only the first is visible from the Editor.
There is a customer who would like to view and edit the IOther series through the editor.
uses StatChar, Series;
procedure TForm1.FormCreate(Sender: TObject);
var Series1: TFastLineSeries;
    Series2: TFastLineSeries;
    TeeFunction1: TBollingerFunction;
begin
  Chart1.View3D:=false;
  Series1:=Chart1.AddSeries(TFastLineSeries) as TFastLineSeries;
  Series1.Pen.Width:=2;
  Series1.FillSampleValues(100);
  Series2:=Chart1.AddSeries(TFastLineSeries) as TFastLineSeries;
  TeeFunction1:=TBollingerFunction.Create(self);
  Series2.FunctionType:=TeeFunction1;
  Series2.DataSource:=Series1;
end;
