Hi richfit,

Yes, you can achieve that changing ValueLists sorting like and populating series like this:

Code: Select all

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var Series1: TFastLineSeries;
    i: Integer;
begin
  Series1:=TFastLineSeries.Create(Self);
  Series1.XValues.Order:=loNone;
  Series1.YValues.Order:=loAscending;

  for i:=0 to 10 do
    Series1.AddXY(random, i);

  Chart1.AddSeries(Series1);
  Chart1.View3D:=False;
end;
