Hello,
The simple code below reproduce the problem when the values are negative or different as 0.

procedure TForm1.FormCreate(Sender: TObject);
var i:Integer;
 ChartTool1: TAxisScrollBarTool;
begin

  Chart1.View3D := false;
  Series1 := TLineSeries.Create(Self);
  Chart1.AddSeries(Series1);
  ChartTool1 := TAxisScrollBarTool.Create(Self);
  Chart1.Tools.Add(ChartTool1);
  Chart1.Legend.Visible := false;
  Series1.XValues.Order :=loAscending;
for i := 5 {0} to 100 do
begin
  Series1.AddXY(i,Random(100));
 // Series1.AddXY(i-50,Random(100));
end;

ChartTool1.Axis := Chart1.Axes.Bottom;
ChartTool1.Arrows := true;
end;
