Chart type rangeBar, xaxis - datetime, y - numeric (need show hours). Something wrong with tooltip for y values

[Orientir]

I am using
"quasar": "^2.6.0",
"vue": "^3.0.0",
"vue3-apexcharts": "^1.4.4"

What I try to do:
Create chart for showing daily user activity. How much time he was online. On yaxix show time, on xaxis show date.

What I get:
Wrong tooltip info.
Expected range values: 6.20 - 7.30
Gotted range values: 6 - 7

My code:

<apexchart :options="chartOptions" :series="chartSeries" ref="login_chart"></apexchart>




chartOptions: {
        chart: {
          type: "rangeBar",
          id: 'login_chart'
        },
        plotOptions: {
          bar: {
            isDumbbell: true,
            dumbbellColors: [['#EC7D31', '#36BDCB']]
          },
        },
        xaxis: {
          type: 'category',
          labels: {
            format: 'dd MMM',
            datetimeFormatter: {
              year: 'yyyy',
              month: 'MMM \'yy',
              day: 'dd MMM'
            },
          }
        },

        tooltip: {
          theme: "dark",
          y: {
            formatter: function(value, data) {
              console.log(value, data)
              if (data) {
                let w = data.w;
                let seriesIndex = data.seriesIndex;
                let dataPointIndex = data.dataPointIndex;
                const start = parseFloat(w.globals.series[seriesIndex][dataPointIndex]);
                return start.toFixed(2);
              }
              return value
            }
          }
        },
        yaxis: {
          type: "numeric",
          forceNiceScale: true,
        }
}




updateLoginChart() {
      if (!this.workerHistory) {
        return;
      }
      this.loginLoading = true;
      const chartData = [];
      Object.keys(this.workerHistory).forEach((date) => {
        let d = new Date(date);
        d = d.toLocaleDateString('en-US', { month: 'short', day: 'numeric' });
        let short_data = {name: d, data: []};
        this.workerHistory[date].forEach((session) => {
          const dateKey = new Date(session.date);

          short_data.data.push({
            x: dateKey.toISOString().split('T')[0],
            y: [
              parseFloat(session.login),
              parseFloat(session.logout)
            ],
          });
        });
        chartData.push(short_data);
      });

      console.log(JSON.stringify(chartData))
      ApexCharts.exec('login_chart', 'updateSeries', chartData, true);
      this.loginLoading = false;
      this.$refs.login_chart?.updateSeries(chartData);
      console.log(this.$refs.login_chart)
      // this.$refs.login_chart?.render();
