   ### What problem does this feature solve?
   
   demo：
   
   
   `function randomData() {
     now = new Date(+now + oneDay);
     value = value + Math.random() * 21 - 10;
     return {
       name: now.toString(),
       value: [
         [now.getFullYear(), now.getMonth() + 1, now.getDate()].join('/'),
         Math.round(value)
       ]
     };
   }
   let data = [];
   let now = new Date(1997, 9, 3);
   let oneDay = 24 * 3600 * 1000;
   let value = Math.random() * 1000;
   for (var i = 0; i < 1000; i++) {
     data.push(randomData());
   }
   option = {
     title: {
       text: 'Dynamic Data & Time Axis'
     },
     xAxis: {
       type: 'time',
       splitLine: {
         show: false
       }
     },
     yAxis: {
       type: 'value',
       min: 'dataMin',
         max: 'dataMax',
       boundaryGap: [0, '100%'],
       splitLine: {
         show: false
       }
     },
     series: [
       {
         name: 'Fake Data',
         type: 'line',
         showSymbol: false,
         data: data,
         animationDurationUpdate: 1000,
       }
     ]
   };
   setInterval(function () {
     for (var i = 0; i < 5; i++) {
       data.shift();
       data.push(randomData());
     }
     myChart.setOption({
       series: [
         {
           data: data
         }
       ]
     });
   }, 1000);`
   
   ### What does the proposed API look like?
