Constructor Detail

### XYBubbleRenderer

    public XYBubbleRenderer()

  Constructs a new renderer.

### XYBubbleRenderer

    public XYBubbleRenderer(int scaleType)

  Constructs a new renderer with the specified type of scaling.

  Parameters:
    `scaleType` - the type of scaling (must be one of: `SCALE_ON_BOTH_AXES`, `SCALE_ON_DOMAIN_AXIS`, `SCALE_ON_RANGE_AXIS`).

Method Detail
