Jfreechart的基础图表用法与在web项目中调用
下面是我自己学习时测试的例子，一天就可以搞定，写的比较简单，基本的功能都有，具体的属性百度，一般的都有解答，希望能够对你们有所帮助
jar包环境
到官网http://www.jfree.org/jfreechart/下载资源包文件

将包文件放到你的项目里面，直接写java类，可以在java类的main方法里面直接生成图片
如例子
public class BarChartDemo {
/**
* 获取一个演示用的组合数据集对象
*
* @return
*/
private static CategoryDataset getDataSet() {
DefaultCategoryDataset dataset = new DefaultCategoryDataset();
dataset.addValue(100, "北京", "苹果");
dataset.addValue(120, "上海", "苹果");
dataset.addValue(160, "广州", "苹果");
dataset.addValue(210, "北京", "梨子");
dataset.addValue(220, "上海", "梨子");
dataset.addValue(230, "广州", "梨子");
dataset.addValue(330, "北京", "葡萄");
dataset.addValue(340, "上海", "葡萄");
dataset.addValue(340, "广州", "葡萄");

dataset.addValue(510, "北京", "荔枝");
dataset.addValue(530, "上海", "荔枝");
dataset.addValue(510, "广州", "荔枝");
return dataset;
}
/**

*/
private static void processChart(JFreeChart chart) {
CategoryPlot plot = chart.getCategoryPlot();
CategoryAxis domainAxis = plot.getDomainAxis();
ValueAxis rAxis = plot.getRangeAxis();
chart.getRenderingHints().put(RenderingHints.KEY_TEXT_ANTIALIASING,
RenderingHints.VALUE_TEXT_ANTIALIAS_OFF);
TextTitle textTitle = chart.getTitle();
textTitle.setFont(new Font("宋体", Font.PLAIN, 20));

rAxis.setLabelFont(new Font("宋体", Font.PLAIN, 12));
chart.getLegend().setItemFont(new Font("宋体", Font.PLAIN, 12));
//3d时设置

}
/**

} catch (Exception e) {

}
}
}
public void createZhu(){
// 1. 得到数据
CategoryDataset dataset = getDataSet();
// 2. 构造chart
JFreeChart chart = ChartFactory.createBarChart3D(
"水果产量图", // 图表标题
"水果", // 目录轴的显示标签--横轴
"产量", // 数值轴的显示标签--纵轴
dataset, // 数据集
PlotOrientation.VERTICAL, // 图表方向：水平、
true, // 是否显示图例(对于简单的柱状图必须
false, // 是否生成工具
false // 是否生成URL链接
);
// 3. 处理chart中文显示问题
processChart(chart);

// 4. chart输出图片
writeChartAsImage(chart);

// 5. chart 以swing形式输出
ChartFrame pieFrame = new ChartFrame("XXX", chart);
pieFrame.pack();
pieFrame.setVisible(true);
}
public static void main(String[] args) throws IOException {
BarChartDemo demo = new BarChartDemo();
//demo.createZhu();//3d条形图

｝
