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.
