   i has try but it's really hard. You can help me piece code in formatter.
   ```
   
   var dataCount = 1440;
   var data = generateData(dataCount);
   
   var option = {
       title: {
           text: echarts.format.addCommas(dataCount) + ' Data',
           left: 10
       },
       toolbox: {
           feature: {
               dataZoom: {
                   yAxisIndex: false
               },
               saveAsImage: {
                   pixelRatio: 2
               }
           }
       },
       tooltip: {
           trigger: 'axis',
           axisPointer: {
               type: 'shadow'
           }
       },
       grid: {
           bottom: 90
       },
       dataZoom: [],
       xAxis: {
           // type: category,
           data: data.categoryData,
           scale: true,
           min: 'dataMin',
           max: 'dataMax',
           axisPointer: {
               show: true
           },
           axisLabel: {
               formatter: function (value, idx) {
                 var date = new Date(value);
                 return idx === 0 ?
                 '00:00' + [date.getDate(), date.getMonth() + 1, 
date.getFullYear()].join('/')
                 : [date.getHours(), date.getMinutes() < 10 ? 
`0${date.getMinutes()}` : date.getMinutes()].join(':');
               }
             },
           silent: true,
           boundaryGap: false
       },
       yAxis: {
           splitArea: {
               show: false
           }
       },
       series: [{
           type: 'line',
           data: data.valueData,
           // Set `large` for large data amount
           large: true
       }]
   };
   
   function generateData(count) {
       var baseValue = Math.random() * 1000;
       var time = +new Date(2011, 0, 1);
       var smallBaseValue;
   
       function next(idx) {
           smallBaseValue = idx % 30 === 0
               ? Math.random() * 700
               : (smallBaseValue + Math.random() * 500 - 250);
           baseValue += Math.random() * 20 - 10;
           return Math.max(
               0,
               Math.round(baseValue + smallBaseValue) + 3000
           );
       }
   
       var categoryData = [];
       var valueData = [];
   
       for (var i = 0; i < count; i++) {
           categoryData.push(echarts.format.formatTime('yyyy-MM-dd\nhh:mm:ss', 
time));
           valueData.push(next(i).toFixed(2));
           time += 60000;
       }
   
       return {
           categoryData: categoryData,
           valueData: valueData
       };
   }
