Description sandra pazos 2013-11-21 04:01:43 EST 
When you there is a ColorLine tool in a Chart with AllowDrag property to false, if you scroll the Chart the ColorLine is drawn out of bounds of Chart.
  TForm1 = class(TForm)
    Chart1: TChart;
    Series1: TFastLineSeries;
    ChartTool1: TColorLineTool;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
Series1.FillSampleValues(100);
ChartTool1.Axis := Chart1.Axes.Left;
ChartTool1.Value := Series1.YValue[3];
ChartTool1.AllowDrag := False;
ChartTool1.NoLimitDrag := False;
end;
The same problem occurs in TeeChartFor.Net.

Fixed.

When AllowDrag is True, scrolling outside the chart will force the color line position to be inside, so it will be always visible.

When AllowDrag is False, the color line will not be painted if its outside the axis Min to Max range.
