2.引入自己需要的示例图形

option = {
    title: {
        text: '堆叠区域图'
    },
    tooltip : {
        trigger: 'axis',
        axisPointer: {
            type: 'cross',
            label: {
                backgroundColor: '#6a7985'
            }
        }
    },
    legend: {
        data:['邮件营销','联盟广告','视频广告','直接访问','搜索引擎']
    },
    toolbox: {
        feature: {
            saveAsImage: {}
        }
    },
    grid: {
        left: '3%',
        right: '4%',
        bottom: '3%',
        containLabel: true
    },
    xAxis : [
        {
            type : 'category',
            boundaryGap : false,
            data : ['周一','周二','周三','周四','周五','周六','周日']
        }
    ],
    yAxis : [
        {
            type : 'value'
        }
    ],
    series : [
        {
            name:'邮件营销',
            type:'line',
            stack: '总量',
            areaStyle: {},
            data:[120, 132, 101, 134, 90, 230, 210]
        },
        {
            name:'联盟广告',
            type:'line',
            stack: '总量',
            areaStyle: {},
            data:[220, 182, 191, 234, 290, 330, 310]
        },
        {
            name:'视频广告',
            type:'line',
            stack: '总量',
            areaStyle: {},
            data:[150, 232, 201, 154, 190, 330, 410]
        },
        {
            name:'直接访问',
            type:'line',
            stack: '总量',
            areaStyle: {normal: {}},
            data:[320, 332, 301, 334, 390, 330, 320]
        },
        {
            name:'搜索引擎',
            type:'line',
            stack: '总量',
            label: {
                normal: {
                    show: true,
                    position: 'top'
                }
            },
            areaStyle: {normal: {}},
            data:[820, 932, 901, 934, 1290, 1330, 1320]
        }
    ]
};

3.jsp页面调整图形位置大小

<div class="left div_any02" style="width:100%;">
            <div class="div_any_child" style="width:99%;position:relative;height:65%">
                <div class="div_any_title"><img src="${pageContext.request.contextPath}/images/title_3.png">集团员工人数增加趋势(%)</div>
                <p id="sortChart1" style="width:97.5%;height:95%;display: inline-block;padding-left: 0.25%;padding-top:4.2%"></p>
            </div>
        </div>

4.js中请求数据

function init(){
	  $.ajax({
	      url : 'echarts/personOfTowYears',
	      async : false,
	      cache : false,
	      success: function(responseText) {
	          //请求成功时处理
	    	  var agebar = echarts.init(document.getElementById('agebar'));
	    	  var responseText = eval('(' + responseText + ')'); 
	            var lastall = responseText.lastall;
	            var nowall = responseText.nowall;
	            var times = responseText.times;
	            agebar.setOption({
	        		tooltip : {
	                    trigger: 'axis',
	                    axisPointer : {            // 坐标轴指示器,坐标轴触发有效
	                        type : 'shadow'        // 默认为直线,可选为:'line' | 'shadow'
	                    }
	                },
	                color:['#4472C5','#ED7C30'],
	                legend: {
