ScaleView: ISpeedometerScaleView;

ArrowView: ISpeedometerArrowView;

Begin

s := SpeedometerBox1.Speedometer;

v := s.View;

s.BeginUpdate;

ScaleView := v.ScaleViews.Item(0);

ArrowView := ScaleView.ArrowViews.Item(0);

ArrowView.Background.Color := GxColor.FromName("Green");

ArrowView.Length := 0.8;

ArrowView.Shape := SpeedometerArrowShapes.Triangle;
