Description yeray alonso 2016-11-30 10:24:04 EST 
Using the following code, if you drag the TChartScrollBar to the bottom, the left axis scrolls to show the bar at pos 5, but there more values below.

uses Chart, TeeScroB, Series;

var Chart1: TChart;
    ScrollBar1: TChartScrollBar;
    horizBar1: THorizBarSeries;

procedure TForm1.FormCreate(Sender: TObject);
begin
   Chart1 := TChart.Create(Self);
   Chart1.Parent := Self;
   Chart1.Align := alClient;

   horizBar1:=Chart1.AddSeries(THorizBarSeries) as THorizBarSeries;
   horizBar1.FillSampleValues(20);
   horizBar1.AutoBarSize:=True;

   Chart1.Axes.Left.SetMinMax(0, 5);

   ScrollBar1 := TChartScrollBar.Create(Self);
   ScrollBar1.Parent := Self;
   ScrollBar1.Align := alRight;
   ScrollBar1.Kind := sbVertical;
   ScrollBar1.Width := 17;
   ScrollBar1.Min := 0;
   ScrollBar1.Max := 100;
   ScrollBar1.Chart := Chart1;
   ScrollBar1.RecalcPosition();
end;
