    <p>I have found <a href="http://www.swtchart.org" rel="nofollow noreferrer">SWTChart library</a> and just wonder how it would be possible to select with the mouse a range e.g. 1 to 3 on the x-axis and I would get all y-axis values which belongs to the selected x values.</p> <p><a href="http://www.swtchart.org/screenshots/img/area.png" rel="nofollow noreferrer">a busy cat http://www.swtchart.org/screenshots/img/area.png</a></p> <pre><code>package org.swtchart.examples; import org.eclipse.swt.SWT; import org.eclipse.swt.layout.FillLayout; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; import org.swtchart.Chart; import org.swtchart.ILineSeries; import org.swtchart.ISeries.SeriesType; /** * An example for area chart. */ public class AreaChartExample { private static final double[] ySeries1 = { 0.1, 0.38, 0.71, 0.92, 1.0 }; private static final double[] ySeries2 = { 1.2, 3.53, 3.1, 0.1, 0.5 }; /** * The main method. * * @param args * the arguments */ public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.setText("Area Chart"); shell.setSize(500, 400); shell.setLayout(new FillLayout()); createChart(shell); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) { display.sleep(); } } display.dispose(); } /** * create the chart. * * @param parent * The parent composite * @return The created chart */ static public Chart createChart(Composite parent) { // create a chart Chart chart = new Chart(parent, SWT.NONE); // set titles chart.getTitle().setText("Area Chart"); // create line series ILineSeries lineSeries1 = (ILineSeries) chart.getSeriesSet() .createSeries(SeriesType.LINE, "line series 1"); lineSeries1.setYSeries(ySeries1); lineSeries1.setLineColor(Display.getDefault().getSystemColor( SWT.COLOR_RED)); lineSeries1.enableArea(true); ILineSeries lineSeries2 = (ILineSeries) chart.getSeriesSet() .createSeries(SeriesType.LINE, "line series 2"); lineSeries2.setYSeries(ySeries2); lineSeries2.enableArea(true); // adjust the axis range chart.getAxisSet().adjustRange(); return chart; } } </code></pre> <p>How is it possible to include a mouse event for selecting a range in the above example?</p> <p>Thank you in advance.</p>

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.
