highcharts - 如何在 HIGHCHARTS 上的一个系列中包含两个数据？

Question

我正在使用 highcharts 堆叠和分组列来制作下图:

我一直无法让它工作，我有以下代码:

$(function () {
    var chart;
    $(document).ready(function() {
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                type: 'column'
            },
            title: {
                text: 'Types of answer'
            },
            subtitle: {
                text: 'SORT BY: Ages'
            },
            xAxis: {
                categories: ['First Test','Second Test','Third Test']
            },
            yAxis: {
                min: 0,
                title: {
                    text: 'Numero de pacientes'
                },
                stackLabels: {
                    enabled: true,
                    style: {
                        fontWeight: 'bold',
                        color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
                    }
                }
            },
            legend: {
                layout: 'vertical',
                align: 'right',
                verticalAlign: 'top',
                x: -150,
                y: -13,
                floating: true,
                backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'white',
                borderColor: '#CCC',
                borderWidth: 1,
                shadow: false
            },
            tooltip: {
                formatter: function() {
                    return '<b>'+ this.x +'</b><br/>'+
                        this.series.name +': '+ this.y +'<br/>'+
                        'Total: '+ this.point.stackTotal;
                }
            },
            plotOptions: {
                column: {
                    stacking: 'normal',
                    dataLabels: {
                        enabled: true,
                        color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
                    }
                }
            },
            series: [{
                name: 'Answer 1',
                data: [variable1, variable7, variable13],
                stack: 'Less than 18',
                data: [variable19, variable25, variable31],
                stack: 'More than 18'
            },{
                name: 'Answer 2',
                data: [variable2, variable8, variable14],
                stack: 'Less than 18',
                data: [variable20, variable26, variable32],
                stack: 'More than 18'
            },{
                name: 'Answer 3',
                data: [variable3, variable9, variable15],
                stack: 'Less than 18',
                data: [variable21, variable27, variable33],
                stack: 'More than 18'
            }]
        });
    });

});

我不想使用另一个系列，因为我不希望它们出现在图例中，我希望图例仅列出

您可以将多个系列链接到一个图例项中以隐藏和显示以及不使用系列中的 linkedTo 属性的内容 -

series: [{
    name: 'Temperature',
    data: averages,
    zIndex: 1,
    marker: {
        fillColor: 'white',
        lineWidth: 2,
        lineColor: Highcharts.getOptions().colors[0]
    }
}, {
    name: 'Range',
    data: ranges,
    type: 'arearange',
    lineWidth: 0,
    linkedTo: ':previous',
    color: Highcharts.getOptions().colors[0],
    fillOpacity: 0.3,
    zIndex: 0
}]
