Like a watch or thermometer, the gauge controls include a Face and a Cover. The Face appears above the background but behind the pointer and decorators, and the Cover appears, like a glass over a thermometer, above all other elements. Shapes can be added to the FaceShapes and CoverShapes collections of the C1Gauge and C1GaugeBase objects. Each the shape has the CenterPointX and CenterPointY properties which define its position in the working area. The default value of these properties is 0.5 (the center of the shape appears in the center of its viewport). Shapes can't have shadow.
