If you have ErrorBar series and you set its error style to LeftRight, the error is drawn incorrectly, the problem only occurs when the error value is biggest than Bar value. Seems the problem is introduced when we fixed the bugs numbers TF02014259 and TV52015184. 

The same problem occurs in TeeCharFor.Net version, bug number=529. The error is drawn correctly if you add Bar values biggest error value. 
Next code reproduces the problem: 
 type
  TForm1 = class(TForm)
    Chart1: TChart;
    Series1: TErrorSeries;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1.View3D:=false;
Series1.AddErrorBar(10, 0.3, 0.7);
Series1.ErrorStyle := essLeftRight;
Chart1.Axes.Bottom.SetMinMax(9.0,11.0);
Chart1.Axes.Left.SetMinMax(0,1);
end;
