    <p>Is it possible to retrieve all rangeAxis-values for a BarChart? I have manage to draw new GridLines(Markers) like this:</p> <p><img src="https://i.stack.imgur.com/HXaUz.png" alt="enter image description here"></p> <p>But I need to know which values that are pressent for the chart in the value-axis to be able to draw all lines. Any ideas how to get all value on the "Value"-axis?(RangeAxis)</p> <pre><code>public class BarChartDemo extends ApplicationFrame { /** * Creates a new demo instance. * * @param title the frame title. */ public BarChartDemo(final String title) { super(title); final CategoryDataset dataset = createDataset(); final JFreeChart chart = createChart(dataset); final ChartPanel chartPanel = new ChartPanel(chart); chartPanel.setPreferredSize(new Dimension(500, 270)); setContentPane(chartPanel); } /** * Returns a sample dataset. * * @return The dataset. */ private CategoryDataset createDataset() { // row keys... final String series1 = "First"; // column keys... final String category1 = "Category 1"; final String category2 = "Category 2"; final String category3 = "Category 3"; // create the dataset... final DefaultCategoryDataset dataset = new DefaultCategoryDataset(); dataset.addValue(3.5, series1, category1); dataset.addValue(4.0, series1, category2); dataset.addValue(3.0, series1, category3); return dataset; } /** * Creates a sample chart. * * @param dataset the dataset. * * @return The chart. */ private JFreeChart createChart(final CategoryDataset dataset) { // create the chart... final JFreeChart chart = ChartFactory.createBarChart( "Bar Chart Demo", // chart title "Category", // domain axis label "Value", // range axis label dataset, // data PlotOrientation.VERTICAL, // orientation false, // include legend false, // tooltips? false // URLs? ); CategoryPlot plot = chart.getCategoryPlot(); plot.getDomainAxis().setCategoryMargin(.01); plot.setRangeGridlinesVisible(false); for(int i=1; i&lt;=4; i++){ Marker marker = new ValueMarker(i); marker.setStroke(new BasicStroke( 1.0f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND, 1.0f, new float[] {3.0f, 8.0f}, 0.0f )); marker.setPaint(new Color(224,224,224)); plot.addRangeMarker(marker); } return chart; } public static void main(final String[] args) { final BarChartDemo demo = new BarChartDemo("Bar Chart Demo"); demo.pack(); demo.setVisible(true); } } </code></pre>

    2. COTried but it seems like its based on "ChartPanel" which seems to be a JPanel. But I want to draw it directly to pdf with iText.

    3. COPlease edit your question to clarify this usage and include an [sscce](http://sscce.org/) that shows what `Marker` you tried; see the demo for examples.

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.
