Description yeray alonso 2014-11-12 06:09:31 EST

This gives an AV at SortCells when drawing the TSurfaceSeries:

uses TeeConst, Chart, TeeSurfa;

var Chart1: TChart;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Caption:=TeeMsg_Version;

  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Self;
  Chart1.Align:=alClient;

  Chart1.View3DOptions.Orthogonal := False;
  //Chart1.Aspect.Rotation:=300; // works fine

  with Chart1.AddSeries(TSurfaceSeries) as TSurfaceSeries do
  begin
    NumXValues := 1;
    FillSampleValues;
  end;
end;

If you increment NumXValues or set a Rotation=300 then it works without problems.
