Var
s: ISpeedometer;
v: ISpeedometerView;
ScaleView: ISpeedometerScaleView;
ArrowView: ISpeedometerArrowView;
Begin
s := SpeedometerBox1.Speedometer;
v := s.View;
s.BeginUpdate;
ScaleView := v.ScaleViews.Item(0);
ArrowView := ScaleView.ArrowViews.Item(0);
ArrowView.AxisOffset:= 0.1;
ArrowView.Background.Color:= GxColor.FromName("Green");
ArrowView.Length := 0.8;
ArrowView.Shape := SpeedometerArrowShapes.Triangle;
