Dynamic Jasper Report Pie Chart

Question

    AbstractColumn columnBranch = ColumnBuilder.getNew().setColumnProperty("branch", String.class.getName())
        .setTitle("Branch").setWidth(new Integer(85)).build();
    AbstractColumn columnAmount = ColumnBuilder.getNew().setColumnProperty("amount", Float.class.getName())
            .build();


    drb.addColumn(columnBranch);
    drb.addColumn(columnAmount);        
    drb.setUseFullPageWidth(true);



    PropertyColumn pc = (PropertyColumn) ColumnBuilder.getNew().setColumnProperty("branch", String.class.getName()).build();
    DJChart djChart = new DJPieChartBuilder()
            // chart
            .setX(10).setY(10).setWidth(210).setHeight(150).setCentered(false).setBackColor(Color.LIGHT_GRAY)
            .setShowLegend(true).setPosition(DJChartOptions.POSITION_FOOTER).setTitle(new StringExpression() {
                public Object evaluate(Map fields, Map variables, Map parameters) {
                    return variables.get("group_state_name");
                }
            }).setTitleColor(Color.DARK_GRAY).setTitleFont(Font.ARIAL_BIG_BOLD).setSubtitle("subtitle")
            .setSubtitleColor(Color.DARK_GRAY).setSubtitleFont(Font.COURIER_NEW_BIG_BOLD)
            .setLegendColor(Color.DARK_GRAY).setLegendFont(Font.COURIER_NEW_MEDIUM_BOLD)
            .setLegendBackgroundColor(Color.WHITE).setLegendPosition(DJChartOptions.EDGE_BOTTOM)
            .setTitlePosition(DJChartOptions.EDGE_TOP).setLineStyle(DJChartOptions.LINE_STYLE_DOTTED)
            .setLineWidth(1).setLineColor(Color.DARK_GRAY).setPadding(5)
            // dataset
            .setKey(pc)
            .addSerie(ColumnBuilder.getNew().setColumnProperty("amount", Float.class.getName()).build())
            // plot
            .setCircular(true).build();
    drb.addChart(djChart);

How to generate chart without having to generate the columns using Dynamic Jasper reports? and without using the abstract column builder?

If I'm understanding your question correctly, use addField instead of addColumn
