Showing multiple data with same X and Y in highchart [closed]

I try using highchart in react-native to show 6 data from the state, and it works the data shown. But because the 6 data have same X and Y, so the data were shown but stacking so it looks like there is only one data (the X is the time when the data get the post, and the Y the day when the data get the post). Is there any way to make the data all appear in the chart. Thankyou before.

This is the chart look like :

This is my highchart conf :

var conf= {
        chart: {
            type: 'scatter',
            backgroundColor: '#233767',
            zoomType: 'xy',
        },
        xAxis: {
          type: 'datetime',
          labels: {
              formatter: function () {
                return Highcharts.dateFormat('%Y-%m-%d', this.value);
              },
              style:{
                color:'white'
              }
            },
        },
        yAxis: {
           type: 'datetime',
           lineWidth: 1,
           dateTimeLabelFormats: {
             minute: '%H:%M'
           },
           labels: {
                style:{
                    color:'white'
                  }
           },
           title: {
             enabled: false
           },
           gridLineColor:'transparent'
        },
        plotOptions: {
            scatter: {
                marker: {
                    radius: 5,
                    states: {
                        hover: {
                            enabled: false,
                            lineColor: 'rgb(100,100,100)'
                        }
                    }
                },
                states: {
                    hover: {
                        marker: {
                            enabled: false
                        }
                    }
                },
            }
        },
        tooltip: {
          formatter: function () {
          return '<b>' + this.series.name + '</b><br/>' +
              Highcharts.dateFormat('%Y-%m-%d', this.x) + '<br/>' +
              Highcharts.dateFormat('%H:%M:%S', this.y);
