compare this code:

    private void InitializeChart()
    {
      Bar series = new Bar(tChart1.Chart);
      tChart1.Legend.Visible = false;

      for (int i = 0; i < 3; i++)
      {
        if(i == 2)
          series.Add(i, "Quite Long Category threethreethree");
        else 
          series.Add(i, "Quite Long Category " + i.ToString());
      }

      int degrees = 10;
      tChart1.Axes.Bottom.Labels.Angle = degrees;
      tChart1.Axes.Bottom.Title.Text = $"X-Axis labels with Angle of {degrees} degrees";
    }

to the equivalent in TeeChart.VCL:

procedure TForm1.InitChart;
var series:TBarSeries;
    t:Integer;
begin
  Chart.View3D:=false;
  series:=TBarSeries.Create(Self);
  series.ParentChart:=Chart;
  Chart.Legend.Visible:=false;

  for t:=0 to 2 do
  begin
    if t=2 then
      series.AddBar(t, 'Quite Long Category ' + 'threethreethreethree', clBlue)
    else
      series.AddBar(t, 'Quite Long Category ' + IntToStr(t), clBlue);
  end;

  Chart.Axes.Bottom.LabelsAngle:=10;
  Chart.Axes.Bottom.Title.Text:='X-Axis labels with Angle of 10 degrees';
end;

(see attachment for difference in result - in .NET the axis title is placed at a unnecessarily large distance from the bottom axis labels)
