Как генерировать графики с использованием jfreecharts?

1 голос
/ 23 ноября 2011

Я попытался сгенерировать диаграмму, используя JFreeChart при нажатии кнопки. Я скопировал полный метод ниже. Моя проблема в том, что когда я пытаюсь сгенерировать диаграмму, я получаю сообщение об ошибке, в котором говорится, что класс для DialFrame.

не найден.

Метод 

private void btnPreviewActionPerformed(java.awt.event.ActionEvent evt) {
    jPanel1.setSize(pwid, phei);
    try {
        //Map<String, Object> params = new HashMap<String, Object>();
        Map params = new HashMap();
        params.put("year", comyear.getSelectedItem().toString());
        params.put("comcode", comCompCode.getSelectedItem().toString());
        params.put("comname", comCompNam.getSelectedItem().toString());
        params.put("itcode", comItmCode.getSelectedItem().toString());
        params.put("itname", comItmNam.getSelectedItem().toString());
        createExportChartImage();
        JasperReport jasperReport = JasperCompileManager.compileReport("Report/MIS/ExportChart.jrxml");
        Connection conn = (Connection) ClsCon.cont();
        JasperPrint jasperPrint = JasperManager.fillReport(jasperReport, params, conn);
        JasperViewer.setDefaultLookAndFeelDecorated(true);
        JRViewer jrv = new JRViewer(jasperPrint);
        jrv.setPreferredSize(new Dimension(jPanel1.getSize()));
        JScrollPane reportScroll = new JScrollPane(jrv);
        jPanel1.add(reportScroll);
        setBounds(jPanel1.getBounds());
        setDefaultCloseOperation(DISPOSE_ON_CLOSE);
        jPanel1.add(jrv);
        con.close();

        this.setBounds(0, 0, wid, hei);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, e + "Error 281");
    }
}
