使用 json 数据创建动态 Highcharts 图

Question

我有带有数据的json输出：

[{"hour":"6","value1":"10","value2":"5","value3":"0","value4":45},{"hour":"7","value1":"0","value2":"10","value3":"0","value4":50}]

我需要使用highchart引擎生成图表 这是highchart代码片段，但我不明白如何将数据传递到“系列”和“类别”中：

xAxis: {
        categories: [
            'Jan',
            'Feb',
            'Mar', <------------------------here need to be a hours
            'Apr',
            'May',
            'Jun',
            'Jul',
            'Aug',
            'Sep',
            'Oct',
            'Nov',
            'Dec'
        ],
        crosshair: true
    },
    series: [{
        name: 'value1',     
        data: [49.9, 71.5]   <----------------values 1
    }, {
        name: 'value2',
        data: [83.6, 78.8]   <----------------values 2
    }, {
        name: 'value3',
        data: [48.9, 38.8]

    },
    {
        name: 'value4',
        data: [42.4, 33.2]

    }        ]
});

var json = [{"hour":"6","value1":"10","value2":"5","value3":"0","value4":45},{"hour":"7","value1":"0","value2":"10","value3":"0","value4":50}];
var categories = [], data1 = [], data2 = [], data3 = [], data4 = [];
for(var i in json){
   var hour = (parseInt(json[i].hour));

   categories.push(hour );

   data1.push(parseInt(json[i].value1));
   data2.push(parseInt(json[i].value2));
   data3.push(parseInt(json[i].value3));
   data4.push(parseInt(json[i].value4));
}

    Highcharts.chart('container', {
        chart: {
            type: 'column'

xAxis: {
        categories: categories ,

                }

    series: [{

        data: data1
