使用DotNet.Highcharts分组的类别

Question

我尝试使用类似于此示例的DotNet.Highcharts构建分组类别条形图：http://www.highcharts.com/plugin-registry/single/11/Grouped-Categories

我知道如何设置自己的类别：

String[] myCategories = new String[] { "Category1", "Category2" };

DotNet.Highcharts.Highcharts chart = new DotNet.Highcharts.Highcharts("chart")
.SetXAxis(new XAxis
{
   Categories = myCategories
})

但是我无法使用DotNet.Highcharts和子类别来初始化此图表，这需要与此示例类似的代码

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

有任何想法如何完成它？

谢谢！
