In this example, only the first axis label is drawn:

    var Series1=Chart1.addSeries(new Tee.Bar());
    Series1.data.values=[200];
    Series1.data.x=[0];
    Series1.data.labels=["Label1"];
    Series1.stacked="sideAll";

    var Series2=Chart1.addSeries(new Tee.Bar());
    Series2.data.values=[100];
    Series2.data.x=[1];
    Series2.data.labels=["Label2"];
    Series2.stacked="sideAll";

    var Series3=Chart1.addSeries(new Tee.Bar());
    Series3.data.values=[300];
    Series3.data.x=[2];
    Series3.data.labels=["Label3"];
    Series3.stacked="sideAll";

In VCL, the same code draws all the three axis labels:

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=false;

  with Chart1.AddSeries(TBarSeries) as TBarSeries do
  begin
    AddXY(0, 200, 'Label1');
    MultiBar:=mbSideAll;
  end;

  with Chart1.AddSeries(TBarSeries) as TBarSeries do
  begin
    AddXY(1, 100, 'Label2');
    MultiBar:=mbSideAll;
  end;

  with Chart1.AddSeries(TBarSeries) as TBarSeries do
  begin
    AddXY(2, 300, 'Label3');
    MultiBar:=mbSideAll;
  end;
end;
