    <p>I'm using the Jfree chart in my struts application. Y-Axis is Over Shipment Pieces and X-Axis is Supplier Code and secondary axis is used for the Over Shipment %. What the problem i faced here is , If the Over Shipment % values all comes to Zero it hide the X-Axis Supplier Value also. How can i overcome to avoid this. I have attached here screen shot for your consideration. Thanks to all to read this question.</p> <p><img src="https://i.stack.imgur.com/tjg6h.png" alt="enter image description here"></p> <p>I pasted my code here for your clear understanding,</p> <pre><code>/** * * @param response * @throws IOException */ public void writeOccurrenceBasedParetoChart(HttpServletResponse response) throws IOException { String METHOD_NAME = "writeOccurrenceBasedParetoChart"; log.entering(CLASS_NAME, METHOD_NAME); CategoryDataset dataset1 = createDataSetForPercentBasedChart1(); CategoryDataset dataset2 = createDataSetForPercentBasedChart2(); String rangeAxisLabel = ""; String numOfSupplrs = ""; //Behind Schedule "4" if(searchRatingElement.equalsIgnoreCase("4")) { System.out.println("*******************searchRatingElement"+searchRatingElement); rangeAxisLabel = I18nMessageUtil.getMessage(CommonUtil.getLocale(), "label.reports.wdid.ovrshptpcs"); } else { rangeAxisLabel = I18nMessageUtil.getMessage(CommonUtil.getLocale(), "label.reports.wdid.ovrshptpcs"); } JFreeChart chart = ChartFactory.createBarChart( "", // chart title "", // domain axis label rangeAxisLabel, // range axis label dataset1, // data PlotOrientation.VERTICAL, // orientation true, // include legend true, // tooltips? false // URLs? ); // NOW DO SOME OPTIONAL CUSTOMISATION OF THE CHART... // set the background color for the chart... chart.setBackgroundPaint(Color.white); CategoryPlot plot = (CategoryPlot) chart.getPlot(); plot.setBackgroundPaint(Color.lightGray); plot.setDataset(1, dataset2); plot.mapDatasetToRangeAxis(1, 1); CategoryItemRenderer renderer1 = plot.getRenderer(); renderer1.setSeriesItemLabelGenerator(0,new CategoryItemLabelGenerator() { public String generateRowLabel(final CategoryDataset arg0, final int arg1) { // TODO Auto-generated method stub return null; } public String generateLabel(final CategoryDataset dataset1,final int series,final int category) { String result = null; //CHAPTER 12.

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.
