CentralS: ISpeedometerCentralShape;
CentralSBack: ISpeedometerBackground;
Begin
s := SpeedometerBox1.Speedometer;
v := s.View;
s.BeginUpdate;
CentralS := v.CentralShape;
CentralSBack := CentralS.Background;
CentralSBack.Type :=SpeedometerBackgroundType.Gradient;
CentralSBack.Color :=GxColor.FromName("Red");
CentralSBack.GradientColor:= GxColor.FromName("Green");
CentralS.ShapeOrder :=SpeedometerArrowCircleOrder.BelowArrow;
CentralS.Radius := 0.7;
s.EndUpdate;
End Sub Button1OnClick;
