Description christopher ireland 2015-09-03 07:46:25 EDT 
Reproducible using the following code:

procedure TForm1.InitializeChart;
var tmpS : TBarSeries;
    subA : TChartAxis;
begin
   Chart1.View3D:=false;

   tmpS := TBarSeries(Chart1.AddSeries(TBarSeries));
   tmpS.FillSampleValues();


   subA:=Chart1.Axes.Left.SubAxes.Add;
   subA.Increment:=500/3;
end;
Comment 1 marc meumann 2016-10-17 11:06:06 EDT 
Axis can only calculate location with respect to Label text width (or height) after the paint has cycled once. For sub Axes we recommend taking the size from the parent axis.

eg.

procedure TForm1.InitializeChart;
var tmpS : TBarSeries;
    subA : TChartAxis;
begin
   Chart1.View3D:=false;

   tmpS := TBarSeries(Chart1.AddSeries(TBarSeries));
   tmpS.FillSampleValues();


   subA:=Chart1.Axes.Left.SubAxes.Add;
   subA.Increment:=500/3;

   subA.LabelsSize := Chart1.Axes.Left.MaxLabelsWidth;  //<- here
end;
