URL: https://github.com/apache/incubator-echarts/issues/13999


   The code example on the official website can't run normally locally。
   the website is 
[https://echarts.apache.org/examples/zh/editor.html?c=doc-example/tutorial-dynamic-data](https://echarts.apache.org/examples/zh/editor.html?c=doc-example/tutorial-dynamic-data)
   
   Correct code
   
   ```javascript
   var base = +new Date(2014, 9, 3);
   var oneDay = 24 * 3600 * 1000;
   var date = [];
   
   var data = [Math.random() * 150];
   var now = new Date(base);
   
   function addData(shift) {
       now = [now.getFullYear(), now.getMonth() + 1, now.getDate()].join('/');
       date.push(now);
       data.push((Math.random() - 0.4) * 10 + data[data.length - 1]);
   
       if (shift) {
           date.shift();
           data.shift();
       }
   
       now = new Date(+new Date(now) + oneDay);
   }
   
   for (var i = 1; i < 100; i++) {
       addData();
   }
   
   option = {
       xAxis: {
           type: 'category',
           boundaryGap: false,
           data: date
       },
       yAxis: {
           boundaryGap: [0, '50%'],
           type: 'value'
       },
       series: [
           {
               name:'成交',
               type:'line',
               smooth:true,
               symbol: 'none',
               stack: 'a',
               areaStyle: {
                   normal: {}
               },
               data: data
           }
       ]
   };
   
   setInterval(function () {
       addData(true);
       myChart.setOption(option);
   }, 500);
   ```
