`void` | `drawAngularGridLines(java.awt.Graphics2D g2, PolarPlot plot, java.util.List ticks, java.awt.geom.Rectangle2D dataArea)` Draw the angular gridlines - the spokes.
`void` | `drawRadialGridLines(java.awt.Graphics2D g2, PolarPlot plot, ValueAxis radialAxis, java.util.List ticks, java.awt.geom.Rectangle2D dataArea)` Draw the radial gridlines - the rings.
`void` | `drawSeries(java.awt.Graphics2D g2, java.awt.geom.Rectangle2D dataArea, PlotRenderingInfo info, PolarPlot plot, XYDataset dataset, int seriesIndex)` Plots the data for a given series.
`LegendItem` | `getLegendItem(int series)` Return the legend for the given series.
`PolarPlot` | `getPlot()` Returns the plot that this renderer has been assigned to.
`void` | `removeChangeListener(RendererChangeListener listener)` Removes a change listener.
`void` | `setPlot(PolarPlot plot)` Sets the plot that this renderer is assigned to.

Method Detail

### drawSeries

    void drawSeries(java.awt.Graphics2D g2,
                    java.awt.geom.Rectangle2D dataArea,
                    PlotRenderingInfo info,
                    PolarPlot plot,
                    XYDataset dataset,
                    int seriesIndex)

  Plots the data for a given series.

  Parameters:
    `g2` - the drawing surface.
    `dataArea` - the data area.
    `info` - collects plot rendering info.
    `plot` - the plot.
    `dataset` - the dataset.
    `seriesIndex` - the series index.

### drawAngularGridLines

    void drawAngularGridLines(java.awt.Graphics2D g2,
                              PolarPlot plot,
                              java.util.List ticks,
                              java.awt.geom.Rectangle2D dataArea)

  Draw the angular gridlines - the spokes.

  Parameters:
    `g2` - the drawing surface.
    `plot` - the plot.
    `ticks` - the ticks.
    `dataArea` - the data area.

### drawRadialGridLines

    void drawRadialGridLines(java.awt.Graphics2D g2,
                             PolarPlot plot,
                             ValueAxis radialAxis,
                             java.util.List ticks,
                             java.awt.geom.Rectangle2D dataArea)

  Draw the radial gridlines - the rings.

  Parameters:
    `g2` - the drawing surface.
    `plot` - the plot.
    `radialAxis` - the radial axis.
    `ticks` - the ticks.
    `dataArea` - the data area.

### getLegendItem

    LegendItem getLegendItem(int series)

  Return the legend for the given series.

  Parameters:
    `series` - the series index.
  Returns:
    The legend item.

### getPlot

    PolarPlot getPlot()

  Returns the plot that this renderer has been assigned to.

  Returns:
    The plot.

### setPlot

    void setPlot(PolarPlot plot)

  Sets the plot that this renderer is assigned to.

  This method will be called by the plot class...you do not need to call it yourself.

  Parameters:
    `plot` - the plot.

### addChangeListener

    void addChangeListener(RendererChangeListener listener)

  Adds a change listener.

  Parameters:
    `listener` - the listener.

### removeChangeListener

    void removeChangeListener(RendererChangeListener listener)

  Removes a change listener.

  Parameters:
    `listener` - the listener.
