Example

Executing the example requires a form with the Button1 button and the SpeedometerBox component named SpeedometerBox1.

Sub Button1OnClick(Sender:Object; Args: IMouseEventArgs);
Var
    s: ISpeedometer;
    v: ISpeedometerView;
    ScaleView, ScaleView1:ISpeedometerScaleView;
Begin
    s := SpeedometerBox1.Speedometer;
    v := s.View;
    s.BeginUpdate;
    s.Scales.Count := 2;
    v.ScaleViews.Count :=2;
    ScaleView := v.ScaleViews.Item(0);
    ScaleView1 := v.ScaleViews.Item(1);
    //The first design
    ScaleView.StartAngle:= 0;
    ScaleView.DeltaAngle:= 180;
    //The second design
    ScaleView1.FontColor:= GxColor.FromName("Green");
    ScaleView1.TextPlacement:= SpeedometerTextPlacementType.OutsideRotated;
    s.EndUpdate;
End Sub Button1OnClick;

After executing the example, on clicking the button, two speedometers are displayed in the SpeedometerBox1 component. Each speedometer has its own formatting.
