栏上的Highchart图例

在highchart中是否可以在每个列中添加图例，同时将每个库伦的值或标签保留在该列顶部（如所附图像），这是我在jsfiddle上的代码在此处输入链接描述

$('#container').highcharts({
"chart": {
    "type": "column",
        "style": {
        "fontFamily": "Arial",
            "fontSize": 12
    },
        "backgroundColor": "transparent",
        "width": 460
},

    "plotOptions": {
    "series": {
        "dataLabels": {
            "enabled": true,
                "format": "${y}"
        },
            "pointPadding": 0,
            "groupPadding": 0.1
    }
},
    "xAxis": [{

    "categories": [
        "Jan",
        "Feb",
        "Mar"],

}],

    "series": [{
    "name": "2014",
        "color": "#231E1E",
        "marker": {
        "radius": 3
    },
        "showInLegend": true,
        "connectNulls": true,
        "tooltip": [

    ],
        "data": [
    10,
    20,
    30]
}, {
    "name": "2015",
        "color": "#1DBEDE",
        "marker": {
        "radius": 3
    },
        "showInLegend": true,
        "connectNulls": true,
        "tooltip": [

    ],
        "data": [
    12,
    22,
    32]
}]

}）;
