使用JasperReports的Bubble Chart是否有任何资源？

Question

我正在寻找 JasperReports 的Bubble Chart教程/示例。我确实获得了我预期的资源，示例程序和 jrxml模板。我已经在网上找Jasper Ultimate Guide了。为什么我问这个问题是为了在这里保留这个问题的答案。不是其他（例如：JavaFX Chart），我必须使用 JasperReports 。

任何正文帮我提供简单的程序，如下面的数据（不是主题）。

Answer 1

我在这里获得了JasperReport Bubble Chart示例的示例程序。

Data.java

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
}

BubbleChartTest.java

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");
    }
}
