请问大家，有没有关于java 图表工具，可以丛数据库中直接生成？

形式就和股票走势图一样。。。有没有这样相关得软件。
我需要在 UNIX 运行。

先谢了。。。

我们是在jCharts基础上修改后完成的，它可以sourceforge.net
上找到的

我用JFREEchart做了一个，效果不错的。能出饼图，直方图，走势图。

推荐StyleReport.在CSDN上有广告。Java的，B/S模式，客户端不需要装任何东东。
最爽的是没有加密，直接修改inetsoft.report.internal.KeyUtil，就可以不受限制使用了:)

我也用JFreeChart写了一个饼图，写成.java运行通过，但改成.jsp确报错，这是为什么呀？

我用JFreeChart也出问题了。希望这方面有经验的朋友指点。
用JFreeChart都需要哪些设置？
我的源代码：


import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartUtilities;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.TextTitle;
import org.jfree.chart.axis.NumberAxis;
import org.jfree.chart.plot.CategoryPlot;
import org.jfree.chart.plot.PiePlot;
import org.jfree.data.time.Day;
import org.jfree.data.DefaultCategoryDataset;
import org.jfree.data.DefaultPieDataset;
import org.jfree.data.time.TimeSeries;
import org.jfree.data.time.TimeSeriesCollection;
//import org.jfree.data.time.TimeSeriesDataPair;

import java.awt.*;
import java.io.*;


public class JFreeChartTest {

public JFreeChartTest() {
	
	
	//图片标题
String title = "空调2002年市场占有率";
//设定数据源
DefaultPieDataset piedata = new DefaultPieDataset();
//第一个参数为名称，第二个参数是double数
piedata.setValue(new Integer(1), 27.3);
piedata.setValue(new Integer(2), 12.2);
piedata.setValue(new Integer(3), 5.5);
piedata.setValue(new Integer(4), 17.0);
piedata.setValue(new Integer(5), 9.0);
piedata.setValue(new Integer(6), 19.0);
//创建JFreeChart，都使用ChartFactory来创建JFreeChart,很标准的工厂设计模式
JFreeChart chart = ChartFactory.createPieChart(title, piedata, true, true, true);
//设定图片标题
chart.setTitle(new TextTitle(title, new Font("隶书", Font.ITALIC, 15)));
//chart.addSubtitle(new TextTitle("2002财年分析", new Font("隶书", Font.ITALIC, 12)));
//设定背景
chart.setBackgroundPaint(Color.white);
//chart.s
//饼图使用一个PiePlot 
PiePlot pie = (PiePlot)chart.getPlot();
//pie.setSectionLabelType(PiePlot.NAME_AND_PERCENT_LABELS);
pie.setSectionLabelType(PiePlot.NAME_AND_VALUE_LABELS);
//设定显示格式(名称加百分比或数值)
pie.setPercentFormatString("#,###0.0#%");
//设定百分比显示格式
pie.setBackgroundPaint(Color.white);
pie.setSectionLabelFont(new Font("黑体", Font.TRUETYPE_FONT, 12));
//设定背景透明度（0-1.0之间）
pie.setBackgroundAlpha(0.6f);
//设定前景透明度（0-1.0之间）
pie.setForegroundAlpha(0.90f);
//输出文件到指定目录
String rfname = "pie_chart" + ".jpeg";
String fileName = "d:/test/" + rfname;
try {
//可以保存文件为jpg或png格式。
ChartUtilities.saveChartAsJPEG(new File(fileName), 100, chart, 600, 600);
//第一个参数为文件名
//第二个参数质量
//第三个参数为哪个chart创建图片
//第四个宽度
//第五个高度
} catch (IOException exz) {
System.out.print("....Cant’t Create image File");
}
}

public static void main(String[] args) {
	JFreeChartTest test = new JFreeChartTest();
}	
}

错误信息：

你需要把几个JAR文件引入到你的
JDK-LIB下面
一个是JCOMMON*.JAR
一个是JFREECHART*.JAR
这样就可以，
我用了你的方法已经可行了

谁那有用JFREECHART作的线状图，有现成的程序帮忙共享一下，发到邮箱liulei0451@hit.edu.cn

2003-09-05 11:11

TimeSeries king = new TimeSeries("啊啊");
for (int i = 1999; i < 2005; i++) {
for (int mon = 0; mon < 12; mon++) {
ibm.add(new Month(mon+1,i),new Double(400-Math.random()*100));
}
}

TimeSeries king = new TimeSeries("比比");
for (int i = 1999; i < 2005; i++) {
ibm.add(new Year(i),new Double(400-Math.random()*100));
}

这是我程序的一段，运行时总是报错：
org.jfree.data.SeriesException: TimeSeries.add(): you are trying to add data where the time period class is org.jfree.data.time.Month, but the TimeSeries is expecting an instance of org.jfree.data.time.Day.

是不是TimeSeries类的add方法只能用 new Day() 类型，我要用new Month(),new Year()类型怎么用

我下载了一个试用版，可是该公司给序列号不对:(
请问如何修改你说的这个inetsoft.report.internal.KeyUtil？
它在哪里？

2004-07-31 10:37

去掉第一行的 package org/jfree/ui/Drawable 试一试

2004-08-10 13:30

呵呵

可以自己手写啊
不是很困难的

请问大家，有没有关于java 图表工具，可以丛数据库中直接生成？

什么是Context上下文？

抽象两种方法：上下文与类型

Content与Context一字之差暗藏逆天极道

语境崩塌：你的注意力正被劫持

Context逻辑之道
