highcharts - 一次动态添加 100 点到 Highcharts

Question

我正在尝试一次将 100 个点动态添加到 Highcharts 并在 1000 个添加点后移动图表。但我没有让它以一种好的方式工作。这是我的代码。我做错了什么？

var chart;
var minData = 1000;

function myFunction() {
    setInterval(function() {
        for (var i = 0; i < 100; i++) {
            var y = Math.random();
            var shift = (chart.series[0].data.length >= minData ? true : false);
            chart.series[0].addPoint(y, false, shift);
        }

        chart.redraw();
    }, 1000);
}


$(document).ready(function() {
    chart = new Highcharts.Chart({
        chart: {
            renderTo: "container",
            type: "spline",
            zoomType: 'x'
        },
        title: {
            text: 'Inverter ~ AC Currents'
        },
        subtitle: {
            text: 'Click and drag in the plot area to zoom in'
        },
        plotOptions: {
            spline: {
                turboThreshold: 5000,
                lineWidth: 2,
                states: {
                    hover: {
                        enabled: true,
                        lineWidth: 3
                    }
                },
                marker: {
                    enabled: false,
                    states: {

                            lineWidth: 1
                        }
                    }
                }
            }
        },
        xAxis: {
            type: 'datetime',
            tickPixelInterval: 100,

            labels: {

                var celcius = parseInt(this.point.t - 273);
                var farenheit = parseInt((9 / 5) * (this.point.t - 273) + 32);
                return ' ' +
                    '<span style="color:blue;font-weight:bold;">' + this.series.name + '</span><br />' +
                    '<span style="color:blue;font-weight:bold;">' + Highcharts.dateFormat('%m/%d/%Y %H:%M:%S', this.point.x) + '</span><br />' +

            }
        },
        exporting: {
            enabled: true
        },
        series: [{
            name: 'Random data',
            data: []
        }]
    });
});
