org.eclipse.nebula.visualization.widgets.figureparts.RoundScaledRamp

public class RoundScaledRamp
extends org.eclipse.draw2d.Figure

A ramp looks like a colorful donut, which is used to indicate the alarm limit, hihi, hi, lo or lolo. The ramp is based on a round scale which is in the same polar coordinate system as the ramp. The ramp could be used for any round scale based widgets, such as meter, gauge and knob etc.
