Description yeray alonso 2017-06-12 04:16:41 EDT 
The default calculation of labels produces overlapping labels when the axis is logarithmic and there are enough values in the series. Ie:

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.View3D:=False;
  Chart1.Legend.Visible:=False;

  Chart1.Axes.Bottom.Logarithmic:=True;
  with Chart1.AddSeries(TLineSeries) as TLineSeries do
  begin
    Pointer.Visible:=True;
    Pointer.Size:=2;

    for i:=1 to 23 do
        AddXY(exp(i), i);
  end;
end;
