Javascript 每天从同一时间开始

Hello在xAxis中，我需要函数getTime（）（例如）在每天早上0:00开始，或者在早上6:00开始，或者在下午12:00开始，或者在下午18:00开始

xAxis: { categories: ["+6","+9","+12","+15","+18","+21","+24","+27","+30","+33","+36","+39","+42","+45","+48","+51","+54","+57","+60","+63","+66","+69","+72","+75","+78","+81","+84","+87","+90","+93","+96","+99","+102","+105","+108","+111","+114","+117","+120","+123",+"126","+129","+132","+135","+138","+141","+144","+147","+150","+153","+156","+159","+162","+165","+168","+171","+174","+177","+180","+183","+186","+189","+192"],

+6始终在00:00、6:00至12:00和18:00开始

因此，我需要知道函数getTime（）在四种不同图形的每天特定时间启动

谢谢

示例：

需要以这种方式设置pointStart和pointInterval：

var date = new Date();
date.setHours(12);
date.setMinutes(0);
date.setSeconds(0);
date.setMilliseconds(0);


var ts = Math.round(date / 1000);
var tsNoon = ts;

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    },
    xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
            day: '%e of %b'
        }
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
        pointStart: tsNoon * 1000, // highcharts asks for miliseconds
        pointInterval: 24 * 3600 * 1000 // one day
    }]
});

你能给我看看这个模型吗？在Highcharts中，您可以设置和。谢谢：我同意，但我需要动态pointstar（从今天12:00开始，明天………从每天12:00开始应该从12:00开始），但我无法使其工作如何

pointStart

可以是动态的？你是说每个点都应该在“12:00:00:000 AM”吗？在这种情况下，请看一看：P E R F E C T，：-）我非常感谢您的努力，我的解释永远不会太好
