对比试百分比echarts 柱状配置项内容和展示

配置项如下
      app.title = '堆叠条形图';
var _should = [150, 150, 150];
var _actual = [50, 100, 150];
option = {
    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'
        },
        formatter: function(data) {
            console.log(data[0].dataIndex);
            var _str = "";
            _str += "应报道: " + _should[data[0].dataIndex] + " 人<br>";
            _str += "实报道: " + _actual[data[0].dataIndex] + " 人<br>";
            _str += "报到率: " + (_actual[data[0].dataIndex] * 100 / _should[data[0].dataIndex]).toFixed(2) + " %";
