Count: Integer;
The Count property determines the number of speedometer scales.
The speedometer contains one scale by default. Change this property to change the number of scales displayed in the speedometer.
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.
