// 设置echarts中的formatter参数
   formatter: function(a) {
   let list = [];
   let listItem = "";
   for (var i = 0; i < a.length; i++) {
    if (i < 2) {
    list.push(
     '<i style="display: inline-block;width: 10px;height: 10px;background: ' +
     a[i].color +
     ';margin-right: 5px;border-radius: 50%;}"></i><span style="width:70px; display:inline-block;">' +
     a[i].seriesName +
     "</span>&nbsp&nbsp：" +
     a[i].value +
     "万"
    );
    } else {
    list.push(
     '<i style="display: inline-block;width: 10px;height: 10px;background: ' +
     a[i].color +
     ';margin-right: 5px;border-radius: 50%;}"></i><span style="width:70px; display:inline-block;">' +
     a[i].seriesName +

   listItem = list.join("<br>");
   return '<div class="showBox">' + listItem + "</div>";
