All Implemented Interfaces:

java.io.Serializable
```
public class CircleClassificationWidget
extends ClassificationWidget
```
Creates the circle widget for the multi-histogram interface. The circle consists of two control points. One controls the radius and eccentricity of the circle/ellipse. The second control point centers the maximum color value within the circle/ellipse.
