Using a Tower Series, if you set an origin (ie 5), it isn't considered as expected. The vertical axis is rescaled accordingly but if you scroll down you see the origin of the tower is zero.

uses TeeSurfa, TeeConst;

var Chart1: TChart;

procedure TForm1.FormCreate(Sender: TObject);
var x, z: Integer;
begin
  Caption:=TeeMsg_Version;

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

  Chart1.Canvas:=TGDIPlusCanvas.Create;

  Chart1.Aspect.Orthogonal:=False;
  Chart1.Chart3DPercent:=100;
  Chart1.Aspect.Zoom:=80;
  Chart1.Legend.Visible:=False;

  Chart1.Axes.Left.Increment:=1;
  Chart1.Axes.Left.SetMinMax(0, 17);

  with Chart1.AddSeries(TTowerSeries) as TTowerSeries do
  begin
    for x:=0 to 3 do
      for z:=0 to 3 do
        AddXYZ(x, 10+x+z, z);

    UseOrigin:=True;
    Origin:=5;
  end;
