public class RoundScale extends org.eclipse.nebula.visualization.xygraph.linearscale.AbstractScale
Round scale has the tick labels and tick marks on a circle. It can be used for any round scale based widget, such meter, gauge, knob etc.
A round scale is comprised of Scale line, tick labels and tick marks which include minor ticks and major ticks.
The endAngle is on the clockwise side of startAngle. Regardless the startAngle and endAngle, the scale will always be drawn in a square. The bounds will be automatically cropped to the square with the max possible size.
