TITLE

Line chart with two or more x-axes (including discontinuous time-axis data), display time in series mode cannot be sorted

BODY

Version

5.0.0

Steps to reproduce

The version of echarts is 5.0.0. I display the time axis in series mode, but the display time in series mode cannot be sorted. The time is small and displayed later (that is, 2020-10-9 00:00:00 is displayed in 2020- 10-9 00:00:02), how do I want the two polylines to be sorted by time? That is, 2020-10-9 00:00:00 is displayed in front of 2020-10-9 00:00:02 in this time ascending format

`var dataTemperature =
[
['2020-10-9 00:00:00', 11], ['2020-10-9 15:00:01', 29], ['2020-10-9 15:00:08', 6]
];
var dataTemperatureB =
[
['2020-10-9 00:00:02', 14], ['2020-10-9 15:00:04', 35], ['2020-10-9 15:00:12', 8]
];

var myChart = echarts.init(document.getElementById('trendChart'));
    var option = {
        tooltip: {
            trigger:'axis',
            position: function (pt) {
                return [pt[0], '10%'];
            }
        },
        backgroundColor:'#ececf2',
        //title: {
        // left:'center',
        // text:'Large data area chart',
        //},
        toolbox: {
            feature: {
                dataZoom: {
                    yAxisIndex:'none'
                },
                restore: {},
                saveAsImage: {}
            }
        },
        legend: {
            data: ['Temperature'],
            x:'left'
        },
        xAxis: {
            // Determine the type according to the x-axis data
            type:'time',
            boundaryGap: false
            // Note: If data is not specified on the x-axis, it will be automatically taken from the series
            //data: []
        },
        yAxis: {
            type:'value',
            boundaryGap: [0, '10%']
        },
        dataZoom: [{
            type:'inside',
            start: 0,
            end: 10
        }, {

        series: [

                data: dataTemperature,
                connectNulls: false
            },
            {
                name:'Phase B current',
                type:'line',
                smooth: true,
                //symbol:'none',
                //sampling:'average',
                //itemStyle: {
                // color:'rgb(300,100,100)'
                //},
                data: dataTemperatureB,
                connectNulls: false
            }
        ]
    };

    myChart.setOption(option);`

What is expected?

How do I want to sort the two polylines according to time? That is, 2020-10-9 00:00:00 is displayed in front of 2020-10-9 00:00:02 in this time ascending format

What is actually happening?

The display time in series mode cannot be sorted, and the shorter time is displayed later (that is, 2020-10-9 00:00:00 is displayed after 2020-10-9 00:00:02), this is wrong

怎么没人解决吗？

this problem exists in last version too !
