Y形时间显示和获取Y项数据echarts 柱状配置项内容和展示

想把Y型弄成几天时间显示，鼠标放上去可以显示秒数，然后鼠标点击的时候获得Y行数据，比如获取2017-12-01 00:00:05

       var time = new Array('Channel1', 'Channel2', 'Channel3', 'Channel4',
     'Channel5', 'Channel6', 'Channel7', 'Channel8', 'Channel9',
     'Channel10', 'Channel11', 'Channel12', 'Channel13', 'Channel14', 'Channel15', 'Channel16');
 var number = [];
 var sdate = "2018-01-09 00:00:00";
 var edate = "2018-01-10 00:00:00";
 var date1 = new Date(sdate);
 var date2 = new Date(edate);
 
 option = {
     title: {
         text: '',
         textStyle: {
             color: 'red',
             fontStyle: 'italic',
             fontWeight: 'bolder',
         },
     },
     tooltip: {
         trigger: 'axis',
         axisPointer: {
             type: 'cross',
             label: {
                 backgroundColor: '#283b56'
             }
         },
         formatter: function(params) {
             return "";
         }
     },
     legend: {
         data: ['最高气温'],
         orient: 'vertical'
     },
     xAxis: {
         name: '',
         type: 'category',
         data: time
     },
     yAxis: {
         name: '',
         type: 'time', 
         min : date1,
         max : date1,
         splitNumber : 10
     },
     series: [{
         type: 'bar',
         boundaryGap: false,
         itemStyle: {
             normal: {
                 color: '#FFFFFF'
             }
         },
         data: [date2, date2, date2, date2, date2, date2, date2, date2, date2, date2, date2, date2, date2, date2, date2, date2]
     }]
 };
 myChart.setOption(option);
 myChart.on('click', function(params) {
     alert(params.name);
 });
