      info - collects plot rendering info.
      plot - the plot.
      dataset - the dataset.
      seriesIndex - the series index.

    • drawAngularGridLines

      void drawAngularGridLines(Graphics2D g2, PolarPlot plot, List ticks, Rectangle2D dataArea)
      Draw the angular gridlines - the spokes.
      Parameters:

      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.
