Code to reproduce:

procedure TForm1.InitChart;
var today : TDateTime;
    i : Integer;
begin
    today := Now;

    Series1.XValues.DateTime:=true;

    For i:=0 to 50 do
    begin
      Series1.AddXY(today, Random);
      today:=today+7;
    end;

    Chart1.Axes.Left.Visible:=false;
    Chart1.Axes.Bottom.LabelsAngle:=90;
    Chart1.Axes.Bottom.DateTimeFormat:='dd/MM/yy hh:mm:ss';
    Chart1.Axes.Bottom.LabelStyle:=talPointValue;
    Chart1.Axes.Bottom.Increment:=14;
end;

Note that the Increment value of 14 is ignored. Also, inconsistent label spacing at some Chart sizes (see attachment).
