今天给各位分享java图表代码的知识，其中也会对java图形界面表格进行解释，如果能碰巧解决你现在面临的问题，别忘了关注本站，现在开始吧！

本文目录一览：

利用java，把SQL SERVER数据库里面的书库绘制成图表的形式，类似于股票那样有XY轴，曲线显示，怎么做啊？

有两种实现方式，一种就是JFreeChart的官方实例MemoryUsageDemo.java.通过一个实现java.Swing.Timer的内部类，在其监听器中将实时数据添加进TimeSeries，由于Timer是会实时执行的，所以这个方法倒是没有什么问题，可以参考代码。

另一种方式就是将实时类实现Runnable接口，在其run()方法中，通过无限循环将实时数据添加进TimeSeries，下面是较简单的实现代码：

java 代码

//RealTimeChart .java

import org.jfree.chart.ChartFactory;

import org.jfree.chart.ChartPanel;

import org.jfree.chart.JFreeChart;

import org.jfree.chart.axis.ValueAxis;

import org.jfree.chart.plot.XYPlot;

import org.jfree.data.time.Millisecond;

import org.jfree.data.time.TimeSeries;

import org.jfree.data.time.TimeSeriesCollection;

public class RealTimeChart extends ChartPanel implements Runnable

{

private static TimeSeries timeSeries;

private long value=0;

public RealTimeChart(String chartContent,String title,String yaxisName)

{

super(createChart(chartContent,title,yaxisName));

}

private static JFreeChart createChart(String chartContent,String title,String yaxisName){

//创建时序图对象

timeSeries = new TimeSeries(chartContent,Millisecond.class);

TimeSeriesCollection timeseriescollection = new TimeSeriesCollection(timeSeries);

JFreeChart jfreechart = ChartFactory.createTimeSeriesChart(title,"时间(秒)",yaxisName,timeseriescollection,true,true,false);

XYPlot xyplot = jfreechart.getXYPlot();

//纵坐标设定

ValueAxis valueaxis = xyplot.getDomainAxis();

//自动设置数据轴数据范围

valueaxis.setAutoRange(true);

//数据轴固定数据范围 30s

valueaxis.setFixedAutoRange(30000D);

valueaxis = xyplot.getRangeAxis();

//valueaxis.setRange(0.0D,200D);

return jfreechart;

}

public void run()

{

while(true)

{

try

{

timeSeries.add(new Millisecond(), randomNum());

Thread.sleep(300);

}

catch (InterruptedException e) { }

}

}

private long randomNum()

{

System.out.println((Math.random()*20+80));

return (long)(Math.random()*20+80);

}

}

//Test.java

import java.awt.BorderLayout;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import javax.swing.JFrame;

public class Test

{

/**

* @param args

*/

public static void main(String[] args)

{

JFrame frame=new JFrame("Test Chart");

RealTimeChart rtcp=new RealTimeChart("Random Data","随机数","数值");

frame.getContentPane().add(rtcp,new BorderLayout().CENTER);

frame.pack();

frame.setVisible(true);

(new Thread(rtcp)).start();

frame.addWindowListener(new WindowAdapter()

{

public void windowClosing(WindowEvent windowevent)

{

System.exit(0);

}

});

}

}

这两中方法都有一个问题，就是每实现一个图就要重新写一次，因为实时数据无法通过参数传进来，在想有没有可能通过setXXX()方式传进实时数据，那样的话就可以将实时曲线绘制类封装起来，而只需传递些参数即可。

java怎么生成折线图,传入月份（1,2,3）生产数量（100,200,300），然后生成一个折线图，最好是曲线图，谢

按照你的要求编写的折线图程序如下：生成的图片放在D盘根目录下，文件名是testline.png

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import javax.swing.JPanel;

import org.jfree.chart.ChartFactory;

import org.jfree.chart.ChartPanel;

import org.jfree.chart.ChartUtilities;

import org.jfree.chart.JFreeChart;

import org.jfree.chart.axis.NumberAxis;

import org.jfree.chart.plot.CategoryPlot;

import org.jfree.chart.plot.PlotOrientation;

import org.jfree.data.category.DefaultCategoryDataset;

import org.jfree.ui.ApplicationFrame;

import org.jfree.ui.RefineryUtilities;

public class LineCharts extends ApplicationFrame {

public LineCharts(String s) {

super(s);

setContentPane(createDemoLine());

}

public static void main(String[] args) {

LineCharts fjc = new LineCharts("折线图");

fjc.pack();

RefineryUtilities.centerFrameOnScreen(fjc);

fjc.setVisible(true);

}

// 生成显示图表的面板 public static JPanel createDemoLine() {

JFreeChart jfreechart = createChart(createDataset());

saveAsFile(jfreechart, "D://testline.png", 500, 300);

return new ChartPanel(jfreechart);

}

// 生成图表主对象JFreeChart public static JFreeChart createChart(DefaultCategoryDataset linedataset) {

//定义图表对象

JFreeChart chart = ChartFactory.createLineChart("LineChart", // chart title

"Time", // domain axis label

"Quantity", // range axis label

linedataset, // data

PlotOrientation.VERTICAL, // orientation

true, // include legend

true, // tooltips

false // urls

);

CategoryPlot plot = chart.getCategoryPlot();

// customise the range axis...

NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();

rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());

rangeAxis.setAutoRangeIncludesZero(true);

rangeAxis.setUpperMargin(1);

rangeAxis.setLabelAngle(Math.PI / 2.0);

return chart; }

//生成数据 public static DefaultCategoryDataset createDataset() {

DefaultCategoryDataset linedataset = new DefaultCategoryDataset();

// 各曲线名称

String series1 = "car";

// 横轴名称(列名称)

String type1 = "Jan";

String type2 = "Feb";

String type3 = "Mar";

linedataset.addValue(100, series1, type1); linedataset.addValue(200, series1, type2);

linedataset.addValue(300, series1, type3);

return linedataset; }

public static void saveAsFile(JFreeChart chart, String outputPath,

int weight, int height) {

FileOutputStream out = null;

try {

File outFile = new File(outputPath);

if (!outFile.getParentFile().exists()) {

outFile.getParentFile().mkdirs();

}

out = new FileOutputStream(outputPath);

// 保存为PNG文件

ChartUtilities.writeChartAsPNG(out, chart, 600, 350);

out.flush();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} finally {

if (out != null) {

try {

out.close();

} catch (IOException e) {

// do nothing

}

}

}

}

}

如何使用java做统计图表

//参考地址去网站下js控件，下面是饼图的代码，下图是我的代码效果

function query1(housetype,redStatisticsList,text0,cashingSum,tranferSum){

!--红包发放数据--

var myrodiusred = echarts.init(document.getElementById('mainrodius'));//ID

var redHousehold = housetype;

var redMoney = redStatisticsList;

var allMoney = 0;//总金额

$.each(redStatisticsList,function(index,item){

allMoney =allMoney+ Number(item.value);

})

optionTwo = {

title : {

text: text0,

subtext: "总金额："+allMoney+"\n\n提现总额："+cashingSum+"\n\n到账总额："+tranferSum,

x:'center'

},

tooltip : {

trigger: 'item',

formatter: "{a} br/{b} ({d}%)"

},

legend: {

orient: 'vertical',

left: 'left',

data: housetype

},

series : [

{

type: 'pie',

radius : '55%',

center: ['50%', '60%'],

data:redMoney,

itemStyle: {

emphasis: {

shadowBlur: 10,

shadowOffsetX: 0,

shadowColor: 'rgba(0, 0, 0, 0.5)'

}

}

}

]

};

        myrodiusred.setOption(optionTwo);

      }

java导出excel图表

通过Java程序导出带图表的excel吗？参考下面用spire.xls.jar来创建Excel图表的方法，这里以创建饼图为例，当然你也可以指定创建其他图表类型，如柱状图、折线图、雷达图、散点图等等：

import com.spire.xls.*;

import com.spire.xls.charts.ChartSerie;

import java.awt.*;

public class CreatePieChart {

public static void main(String[] args) {

//创建Workbook对象

Workbook workbook = new Workbook();

//获取第一个工作表

Worksheet sheet = workbook.getWorksheets().get(0);

//将图表数据写入工作表

sheet.getCellRange("A1").setValue("年份");

sheet.getCellRange("A2").setValue("2002");

sheet.getCellRange("A3").setValue("2003");

sheet.getCellRange("A4").setValue("2004");

sheet.getCellRange("A5").setValue("2005");

sheet.getCellRange("B1").setValue("销售额");

sheet.getCellRange("B2").setNumberValue(4000);

sheet.getCellRange("B3").setNumberValue(6000);

sheet.getCellRange("B4").setNumberValue(7000);

sheet.getCellRange("B5").setNumberValue(8500);

//设置单元格样式

sheet.getCellRange("A1:B1").setRowHeight(15);

sheet.getCellRange("A1:B1").getCellStyle().setColor(Color.darkGray);

sheet.getCellRange("A1:B1").getCellStyle().getExcelFont().setColor(Color.white);

sheet.getCellRange("A1:B1").getCellStyle().setVerticalAlignment(VerticalAlignType.Center);

sheet.getCellRange("A1:B1").getCellStyle().setHorizontalAlignment(HorizontalAlignType.Center);

sheet.getCellRange("B2:C5").getCellStyle().setNumberFormat("\"￥\"#,##0");

//添加饼图

Chart chart = sheet.getCharts().add(ExcelChartType.Pie);

//设置图表数据区域

chart.setDataRange(sheet.getCellRange("B2:B5"));

chart.setSeriesDataFromRange(false);

//设置图表位置

chart.setLeftColumn(3);

chart.setTopRow(1);

chart.setRightColumn(11);

     chart.setBottomRow(20);

//设置图表标题

chart.setChartTitle("年销售额");

chart.getChartTitleArea().isBold(true);

chart.getChartTitleArea().setSize(12);

//设置系列标签

ChartSerie cs = chart.getSeries().get(0);

cs.setCategoryLabels(sheet.getCellRange("A2:A5"));

cs.setValues(sheet.getCellRange("B2:B5"));

cs.getDataPoints().getDefaultDataPoint().getDataLabels().hasValue(true);

chart.getPlotArea().getFill().setVisible(false);

 //保存文档

workbook.saveToFile("output/PieChart.xlsx", ExcelVersion.Version2016);

}

}

饼图创建效果：

excel饼状图效果

java操作word中的excel(对应的是图表，如柱状图)

我.net中也遇到了相同的问题：你可以先看一下下面代码，应该大部分你能用到，只是chart属性可能有点问题，之前尝试成功过，但是由于我不小心删除了一些系统文件里的内容，就有些运行不起来了

我是先循环的word中的shape

foreach (Microsoft.Office.Interop.Word.Shape shape in docFile.Shapes)

{

if(shape.Name=="Chart_图表")

{

shape.Chart.ChartData.Activate();

Microsoft.Office.Interop.Excel.Workbook wb = (Microsoft.Office.Interop.Excel.Workbook)shape.Chart.ChartData.Workbook;

Microsoft.Office.Interop.Excel.Worksheet wSh = (Microsoft.Office.Interop.Excel.Worksheet)wb.Worksheets[1];

//然后添加新数据

for (int r = 0; r tempdt.Rows.Count; r++)

{

for (int k = 0; k tempdt.Columns.Count; k++)

{

Microsoft.Office.Interop.Excel.Range Rng1 = wSh.Cells[r + 2, k + 1] as Microsoft.Office.Interop.Excel.Range;

Rng1.Value = tempdt.Rows[r][k];

}

}

wb.Application.ScreenUpdating = true;

wb.Close(Type.Missing, Type.Missing, Type.Missing);

chart.Refresh();

shape.Chart.Refresh();

}

}
