Constructor Detail

### VectorRenderer

    public VectorRenderer()

  Creates a new `XYBlockRenderer` instance with default attributes.

Method Detail

### findDomainBounds

    public Range findDomainBounds(XYDataset dataset)

  Returns the lower and upper bounds (range) of the x-values in the specified dataset.

  Specified by:
    `findDomainBounds` in interface `XYItemRenderer`
  Overrides:
    `findDomainBounds` in class `AbstractXYItemRenderer`
  Parameters:
    `dataset` - the dataset (`null` permitted).
  Returns:
    The range (`null` if the dataset is `null` or empty).
  See Also:
    `AbstractXYItemRenderer.findRangeBounds(XYDataset)`

### findRangeBounds

    public Range findRangeBounds(XYDataset dataset)

  Returns the range of values the renderer requires to display all the items from the specified dataset.

  Specified by:
    `findRangeBounds` in interface `XYItemRenderer`
  Overrides:
    `findRangeBounds` in class `AbstractXYItemRenderer`
  Parameters:
    `dataset` - the dataset (`null` permitted).
  Returns:
    The range (`null` if the dataset is `null` or empty).
  See Also:
    `AbstractXYItemRenderer.findDomainBounds(XYDataset)`

### drawItem

    public void drawItem(java.awt.Graphics2D g2,
                         XYItemRendererState state,
                         java.awt.geom.Rectangle2D dataArea,
                         PlotRenderingInfo info,
                         XYPlot plot,
                         ValueAxis domainAxis,
                         ValueAxis rangeAxis,
                         XYDataset dataset,

    `crosshairState` - the crosshair state.
    `pass` - the pass index.

### equals

    public boolean equals(java.lang.Object obj)

  Tests this `VectorRenderer` for equality with an arbitrary object. This method returns `true` if and only if:
