Highcharts Highchart自定义x轴值，按年份分组

我想按年份显示条形图x轴组，例如最近我有一个这样的图表

但我想把x轴按年份分组，如下图所示

请告诉我如何在条形图的高图表中实现这一点？

您可以使用组类别扩展

xAxis: {
        categories: [{
            name: "Fruit",
            categories: ["Apple", "Banana", "Orange"]
        }, {
            name: "Vegetable",
            categories: ["Carrot", "Potato", "Tomato"]
        }, {
            name: "Fish",
            categories: ["Cod", "Salmon", "Tuna"]
        }]
    }
