ThinkAdmin中使用echarts的饼状图 并把百分比显示在圆环上

1. 页面

<div class="layui-col-xs12 layui-col-md3">
     <div class="think-box-shadow">
         <div id="main2" style="width:100%;height:350px"></div>
     </div>
 </div>
<!--
循环 可忽略不计
{foreach $levels as $set=>$value}
      {foreach $value as $key=>$vo}
      <div class="layui-col-xs12 layui-col-md3">
          <div class="think-box-shadow">
              <div id="{$key}" style="width:100%;height:350px"></div>
          </div>
      </div>
      {/foreach}
  {/foreach}
-->

2. 页面接收并处理数组

 <label class="layui-hide">
     <textarea id="jsondata2">{$days|json_encode}</textarea>
     <textarea id="jsondata4">{$daysmoy|json_encode}</textarea>
     <textarea id="jsondata3">{$levels|json_encode}</textarea>
 </label>

3. 页面在script中处理并设置号

<script>
    require(['echarts'], function (echarts) {  
        var data2 = JSON.parse($('#jsondata2').html());
        var data4 = JSON.parse($('#jsondata4').html());
        var data3 = JSON.parse($('#jsondata3').html());
        // 总共呢个
        var chart2 = echarts.init(document.getElementById('main2'));
        var chart3 = echarts.init(document.getElementById('main3'));
        window.addEventListener("resize", function () {
            chart2.resize()
            chart3.resize()
        });
        chart3.setOption({
            title: {text: '物业金额总数据', left: 'right'},
            tooltip: {trigger: 'item',formatter: '{a} <br/>{b} : {c} 元 ( {d}% )'},
            legend: {orient: 'vertical', left: 'left'},
            series: [
                {
                    name: '物业金额总数据',
                    type: 'pie',
                    radius: ['40%', '70%'],
                    avoidLabelOverlap: false,
                    label: {
                        // show: false,
                        // position: 'center'  
                        normal: {

                            position:'inner',
                            textStyle: {

                                color:'#fff'
                            },
                            formatter: '{d}%',/*饼状图内显示百分比*/
                        },
                    },
                    emphasis: {
                        label: {

                    }),
                }
            ]
        });
        chart2.setOption({
            title: {text: '物业数量总数据', left: 'right'},
