public class LinearGauge : GaugeBase, IDisposable
Remarks

The Linear Gauge is perfect for showing input values graphically along a linear scale. A linear gauge can have multiple scales, pointers, ranges, state indicators, labels and images. It has a bounded rectangle around it. The top-left corner of the rectangle has coordinates of (0, 0) and the bottom-right corner has coordinates of (100, 100) and every gauge element is drawn inside the bounded rectangle according to the Location property.
