public class CircularGauge : GaugeBase, IDisposable

Remarks

Circular gauges are perfect for presenting values of a specific range. It can be used to create sophisticated gaming applications, dashboards, clocks, industrial equipments and many more.In short it could be used for almost anything one could ever imagine of, for representing a range of values in Circular form. Circular gauge can accommodate multiple scales, pointers, ranges, state indicators, labels and images.It has a virtual bounded rectangle around it. The top-left corner of the virtual bounded rectangle is represented by the co-ordinate(0, 0) and that of the bottom-right is represented by (100, 100).Each and every gauge element is drawn inside the bounded rectangle based on the location property.
