Question

有没有办法创建一个剑道折线图，显示产品价格变化和动态计算的最小 - 最大范围区域（波段）？关于最小 - 最大值，它们被计算为过去5周的算术平均值（周值可能超出范围区域）。

为了做到这一点，我一直尝试合并折线图和范围区域图表但未成功，但只显示了线系列。这就是我试图静态地做的事情（我稍后会尝试从json文件中获取数据）：

系列是一个单一阵列：

series: [{
        type: "rangeArea",
        data: [[5, 11], [5, 13], [7, 15], [10, 17]]
    },{
        name: "Product A",
        data: [7, 16, 13, 12, 10]
    },{
        name: "Product B",
        data: [6, 9, 13, 14, 12]
    },{
        name: "Product C",
        data: [3, 5, 14, 12, 13]
    }]
