如何使用java做统计图表

//参考地址http://echarts.baidu.com/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)

      }
