Setting little ranges in the axes for the Area series and the THighLowSeries they aren't drawn when they should.
They are actually correctly drawn with v8 and this code but not with v2011.04:
uses Chart, Series, ErrorBar;
procedure TForm1.FormCreate(Sender: TObject);
var Chart1: TChart;
begin
  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Form1;
  Chart1.View3D:=false;
//  with Chart1.AddSeries(THighLowSeries) as THighLowSeries do
  with Chart1.AddSeries(TAreaSeries) as TAreaSeries do
  begin
    AddXY(-10000000,100);
    AddXY(10000000,100);
  end;
  Chart1.Axes.Bottom.SetMinMax(15,55);
  Chart1.Axes.Left.SetMinMax(0,200);
end;

Fixed. 
Area series now checks for overflow coordinates (like Line series does).

Check is done at Series.pas TryFixOverflowCoordinates local procedure.

For HighLow series I think the example code is not correct.
HighLow draws vertical lines at X position, and in the test code the X positions are outside the axes range.
