eclipse中用JAVA代码怎么画柱形图表
用jfreechart
jfreechart绘制柱状图

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");
dataset.addValue(300, "C", "3");
dataset.addValue(400, "HTML", "4");
dataset.addValue(400, "CSS", "5");
/*

* CategoryDataset dataset, 设置数据
* PlotOrientation orientation, 设置图表的方向
* boolean legend, 设置是否显示图例
* boolean tooltips,设置是否生成热点工具

*/
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)
{
e.printStackTrace();
}

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();
}
}
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);
}
