eclipse中用JAVA代码怎么画柱形图表
用jfreechart
jfreechart绘制柱状图
import java.io.File;

import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartUtilities;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.DefaultCategoryDataset;
/*

* */
public class BarChart3DDemo
{
public static void main(String[] args)
{
try
{
//设置主题
ChartFactory.setChartTheme(Theme.getTheme());
//构造数据
DefaultCategoryDataset dataset = new DefaultCategoryDataset();
dataset.addValue(100, "JAVA","1");
dataset.addValue(200, "js","1");
dataset.addValue(200, "C++", "2");

JFreeChart chart = ChartFactory.createBarChart3D("编程语言统计", "语言",
"学习人数", dataset, PlotOrientation.VERTICAL, true, false,
false);
//保存图表
ChartUtilities.saveChartAsPNG(new File("E:/chart/BarChart3D.png"), chart, 800, 500);
System.out.println("绘图完成");
}
catch (IOException e)

java怎么从数据库里获得动态数据生成统计图
我这个是使用的echarts的饼图，如果需要使用到其他的图形，可以在echarts的官网上面去找找，上面各种的图都有例子
option = {
title : {
//图中2的位置
text: '某站点用户访问来源',
subtext: '纯属虚构',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{a} br/{b} : {c} ({d}%)"
},
legend: {
orient: 'vertical',
left: 'left',
data: ['直接访问','邮件营销','联盟广告','视频广告','搜索引擎']//图中1的位置
},
series : [ //图中3的位置
{
name: '访问来源',
type: 'pie',
radius : '55%',
center: ['50%', '60%'],
data:[
//这下面就是你从数据库中查询的结果
{value:335, name:'直接访问'},
{value:310, name:'邮件营销'},
{value:234, name:'联盟广告'},
{value:135, name:'视频广告'},
{value:1548, name:'搜索引擎'}
],
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
} }]};
数据具体怎么从后台传送到前台来，楼主应该知道的吧，我这儿就不说了，望采纳！
用java将数据导出到wps表格中，怎么实现
一:页面图片显示预览：
1）如下图：
2）点击导出按钮后预览：
3）最终生成的excel表格图片预览：
二：代码演示：
说明：执行操作时，请先引进导出excel表格的jar文件包。
找到导出按钮所执行的js方法，在java后天查看该方法的实现即可。
1）jsp代码：
