   One simple solution may be: Take Example https://ecomfe.github.io/echarts-examples/public/editor.html?c=bar-waterfall2 and modify it by adding a step line:
   
   ```
   option = {
       title: {
           text: '阶梯瀑布图',
           subtext: 'From ExcelHome',
           sublink: 'http://e.weibo.com/1341556070/Aj1J2x5a5'
       },
       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 (params) {
               var tar;
               if (params[1].value != '-') {
                   tar = params[1];
               }
               else {
                   tar = params[0];
               }
               return tar.name + '<br/>' + tar.seriesName + ' : ' + tar.value;
           }
       },
       legend: {
           data:['支出','收入']
       },
       grid: {
           left: '3%',
           right: '4%',
           bottom: '3%',
           containLabel: true
       },
       xAxis: {
           type : 'category',
           splitLine: {show:false},
           data :  function (){
               var list = [];
               for (var i = 1; i <= 11; i++) {
                   list.push('11月' + i + '日');
               }
               return list;
           }()
       },
       yAxis: {
           type : 'value'
       },
       series: [
           {
               name: '辅助',
               type: 'bar',
