<p>I'm not sure I understand your data, but it may help to normalize the values to an angular range that allows adding the origin, <code>(0, 0)</code>, to the data. In the example below, I chose zero.</p> <p><img src="https://i.stack.imgur.com/yHtzU.png" alt="enter image description here"></p> <pre><code>import java.awt.AlphaComposite; import java.awt.Color; import java.awt.Dimension; import java.awt.EventQueue; import javax.swing.JFrame; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.NumberAxis; import org.jfree.chart.plot.PolarPlot; import org.jfree.chart.renderer.DefaultPolarItemRenderer; import org.jfree.data.xy.XYDataset; import org.jfree.data.xy.XYSeries; import org.jfree.data.xy.XYSeriesCollection; /** @see http://stackoverflow.com/a/12607586/230513 */ public class PolarCharDemo { private static final String title = "PolarChart"; private static final double START = 0; private static final double END = 145; private void display() { JFrame f = new JFrame(title); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); ChartPanel panel = new ChartPanel(createChart(createDataset())); panel.setPreferredSize(new Dimension(500, 500)); f.add(panel); f.pack(); f.setLocationRelativeTo(null); f.setVisible(true); } private JFreeChart createChart(XYDataset dataset) { JFreeChart chart = ChartFactory.createPolarChart( title, dataset, true, false, false); PolarPlot plot = (PolarPlot) chart.getPlot(); plot.setBackgroundPaint(Color.white); plot.setAngleGridlinePaint(Color.black); plot.setRadiusGridlinePaint(Color.lightGray); DefaultPolarItemRenderer r = (DefaultPolarItemRenderer) plot.getRenderer(); r.setFillComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.5f)); for (int i = 0; i < dataset.getSeriesCount(); i++ ) { r.setSeriesFilled(i, true); r.setShapesVisible(false); r.setDrawOutlineWhenFilled(false); } NumberAxis rangeAxis = (NumberAxis) plot.getAxis(); rangeAxis.setTickLabelsVisible(false); return chart; } private XYDataset createDataset() { XYSeriesCollection result = new XYSeriesCollection(); for (int r = 4; r > 0; r--) { XYSeries series = new XYSeries(title + String.valueOf(r)); series.add(0, 0); for (int t = (int) START; t <= END; t++) { series.add(t, r); } result.addSeries(series); } return result; } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new PolarCharDemo().display(); } }); } } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
