Java怎么顯示圖表

java顯示圖表的話，都會(huì)使用一些框架或者其他人已經(jīng)開發(fā)好的工具，比如echart等等，都是很好的圖表繪制工具。

java操作word中的excel(對(duì)應(yīng)的是圖表，如柱狀圖)

我.net中也遇到了相同的問題：你可以先看一下下面代碼，應(yīng)該大部分你能用到，只是chart屬性可能有點(diǎn)問題，之前嘗試成功過，但是由于我不小心刪除了一些系統(tǒng)文件里的內(nèi)容，就有些運(yùn)行不起來了

我是先循環(huán)的word中的shape

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

{

if(shape.Name=="Chart_圖表")

{

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];

//然后添加新數(shù)據(jù)

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做統(tǒng)計(jì)圖表

//參考地址去網(wǎng)站下js控件，下面是餅圖的代碼，下圖是我的代碼效果

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

!--紅包發(fā)放數(shù)據(jù)--

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

var?redHousehold?=?housetype;

var?redMoney?=?redStatisticsList;

var?allMoney?=?0;//總金額

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

allMoney?=allMoney+?Number(item.value);

})

optionTwo?=?{

title?:?{

text:?text0,

subtext:?"總金額："+allMoney+"\n\n提現(xiàn)總額："+cashingSum+"\n\n到賬總額："+tranferSum,

x:'center'

},

tooltip?:?{

trigger:?'item',

formatter:?"{a}?br/{b}?(eysaiai%)"

},

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);

}
