如何在 Highchart 上仅使用 json 对象（无 js 函数）更改系列（分组柱形图）的颜色？

Question

我实际上使用了一个名为 Jedox 的工具，它允许我使用 Highchart.js 库来制作图表。所以我尝试制作一个包含 2 个系列和 4 列的简单图表，它是一个分组柱形图（簇状条形图）。我在 Highchart 上看到可以使用数组“颜色”更改系列的颜色，但是当我使用它时它不起作用。为什么？我也尝试使用 colorByPoint，它正在工作，但它不是我想要的，因为它为类别着色，但在类别中有不同的系列，我希望每个系列都有精确的颜色。我该怎么做？

在您看到代码之前，这里有一些精确性：我将“未定义”放在颜色属性上，因为无法删除这些属性，所以我将它们设为默认值。通常当该值设置为“未定义”时，颜色对应于“颜色”数组中的一种颜色。

在帮助我之前你必须知道的一件重要事情：我不会使用 JS，我只能使用 JSON 仅此而已。

这是我的代码：（它只是一个 json）

默认颜色值为 undefined，而不是字符串 "undefined"。（如果 Jedox 不允许未定义的值，请改为 null）

    "series": [{
            "color": undefined,
            ...
        },
        {
            "color": undefined,
            ...
        }
    ]
