示例1: PieChart

import org.jfree.chart.plot.PiePlot; //導入方法依賴的package包/類
public PieChart() {

    JFreeChart chart = ChartFactory.createPieChart3D("水果產量", data, true, false, false);
    //設置百分比
    PiePlot pieplot = (PiePlot) chart.getPlot();
    DecimalFormat df = new DecimalFormat("0.00%");//獲得一個DecimalFormat對象,主要是設置小數問題
    NumberFormat nf = NumberFormat.getNumberInstance();//獲得一個NumberFormat對象
    StandardPieSectionLabelGenerator sp1 = new StandardPieSectionLabelGenerator("{0}  {2}", nf, df);//獲得StandardPieSectionLabelGenerator對象
    pieplot.setLabelGenerator(sp1);//設置餅圖顯示百分比

    //沒有數據的時候顯示的內容
    pieplot.setNoDataMessage("無數據顯示");
    pieplot.setCircular(false);
    pieplot.setLabelGap(0.02D);

    pieplot.setIgnoreNullValues(true);//設置不顯示空值
    pieplot.setIgnoreZeroValues(true);//設置不顯示負值
    frame1 = new ChartPanel(chart, true);
    chart.getTitle().setFont(new Font("宋體", Font.BOLD, 20));//設置標題字體
    PiePlot piePlot = (PiePlot) chart.getPlot();//獲取圖表區域對象
    piePlot.setLabelFont(new Font("宋體", Font.BOLD, 10));//解決亂碼
    chart.getLegend().setItemFont(new Font("黑體", Font.BOLD, 10));
