Description yeray alonso 2016-11-10 10:35:27 EST 
In the following code we are adding a null point in the center, but it's still drawn, in white:

uses StatChar;

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;

  with Chart1.AddSeries(THistogramSeries) as THistogramSeries do
  begin
    Add(10);

    for i:=0 to 5 do
      Add(YValue[Count-1]+1);

    AddNull(YValue[Count-1]+1);

    for i:=0 to 5 do
      Add(YValue[Count-1]-1);
  end;
end;
