Place a Chart, a Button, a Label and a TeeCommander on the Form. Then use this code to see how "XValues.Order" is "Ascending" after creating the Series:

var Series1: TPointSeries;

procedure TForm1.Button1Click(Sender: TObject);
begin
  case Series1.XValues.Order of
    loNone: Label1.Text:='None';
    loAscending: Label1.Text:='Ascending';
    loDescending: Label1.Text:='Descending';
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Series1:=TPointSeries.Create(Self);
  Chart1.AddSeries(Series1);
end;

Then, open the editor and go to "Series\General". You'll see "SortBy" combobox is set to "None".
