java是否有使用JasperReports的气泡图资源？

Question

我正在寻找Bubble Chart教程/JasperReports示例。我确实得到了预期的资源，示例程序和jrxml模板。我已经在寻找在线和Jasper Ultimate Guide。我问这个问题的原因是把这个问题的答案保留在这里。不是其他的（例如：JavaFX图表），我必须使用JasperReports

任何机构帮助我提供以下数据（不是主题）简单的程序

资料

图表

Answer 1

这里我得到了JasperReport{}示例的示例程序

数据。爪哇

public class Data {
    private String name;
    private double x;
    private double y;
    private double z;

    public Data(String name, double x, double y, double z) {
        this.name = name;
        this.x = x;
        this.y = y;
        this.z = z;
    }
    // getter, setter
}

泡泡试验。爪哇

public class BubbleChartTest {
    public static void main(String[] args) throws Exception {
        List<Data> dataList = new ArrayList<Data>();
        dataList.add(new Data("A", 1d, 3d, 0.3));
        dataList.add(new Data("A", 2d, 3d, 0.2));
        dataList.add(new Data("B", 5d, 6d, 0.4));
        dataList.add(new Data("B", 4d, 3d, 0.2));
        dataList.add(new Data("B", 2d, 5d, 0.1));
        dataList.add(new Data("C", 5d, 6d, 0.2));
        dataList.add(new Data("C", 2d, 3d, 0.3));
        dataList.add(new Data("C", 4d, 5d, 0.4));
        String templateFile = "resources/bubble.jrxml";
        JasperDesign design = JRXmlLoader.load(templateFile);
        JasperReport report = JasperCompileManager.compileReport(design);
        Map parameter = new HashMap();
        JasperPrint print = JasperFillManager.fillReport(report, parameter, new JRBeanCollectionDataSource(dataList));
        JasperExportManager.exportReportToPdfFile(print, "D:/temp/bubble_chart.pdf");
    }
}

泡沫。jrxml
