Description Errol 2014-04-14 21:31:57 EDT 
TBarSeries.YOrigin offset does not work for self-stacked bar charts using a single series. It would be very useful if this could be implemented soon. While strictly an enhancement, it critically affects the charts I want to display.

This works fine for me here. Using the code snippet below I get the chart in the attached screen-shot. Is that what you expected?

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var Series1: TBarSeries;
    i: Integer;
begin
  Series1:=TBarSeries.Create(Self);
  Series1.MultiBar:=mbSelfStack;
  Series1.UseYOrigin:=True;
  Series1.YOrigin:=100;

  for i:=0 to 5 do
    Series1.Add(200);

  Chart1.AddSeries(Series1);
end;

The left axis is rescaled according to the YOrigin set, but is your scroll the chart down, you'll see the bars still start at 0.
Without mbSelfStack, setting YOrigin means the bars start at this position (and also the left axis is rescaled)
