柱状图

(以此为例子，下面各个都一样)

1，edu.hhxy.chart.bar.BarChart1

package edu.hhxy.chart.bar;import javax.servlet.http.HttpSession;import org.jfree.chart.ChartFactory;import org.jfree.chart.JFreeChart;import org.jfree.chart.plot.PlotOrientation;import org.jfree.chart.servlet.ServletUtilities;import org.jfree.data.category.DefaultCategoryDataset;public class BarChart1 {    public static String genBarChart(HttpSession session) throws Exception {        DefaultCategoryDataset dataset = new DefaultCategoryDataset();        dataset.addValue(510, "深圳", "苹果");        dataset.addValue(320, "深圳", "香蕉");        dataset.addValue(580, "深圳", "橘子");        dataset.addValue(390, "深圳", "梨子");        JFreeChart chart=ChartFactory.createBarChart3D("水果销售统计图", "水果", "销售", dataset,                PlotOrientation.VERTICAL, true, true, true);        String fileName=ServletUtilities.saveChartAsPNG(chart, 700, 500, null,session);        return fileName;    }}

在barChart1.jsp引用
