请告诉我如何在条形图中的Highcharts中实现这一目标？

您可以使用群组类别扩展程序。

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