在 echarts 中的数据集对象中绘制更深的值

Question

如何在日期集对象中绘制更深的值

例如

option = {
  legend: {},

  tooltip: { show: true, trigger: "item" },

  xAxis: [
    {
      type: "category",
      name: "Quarters",
      axisTick: { alignWithLabel: true },
    },
  ],

  yAxis: [
    {
      type: "value",
      name: "Profit/Loss",
      nameLocation: "center",
      nameGap: 40,
      splitLine: { show: false },
    },
  ],

  dataset: [
    {
      source: [
        {
          quarter: "2011 Q1",
          profit: { tooltipValue: 40, plotValue: 50 },
          loss: { tooltipValue: 40, plotValue: 50 },
        },
        {
          quarter: "2011 Q2",
          profit: { tooltipValue: 40, plotValue: 50 },
          loss: { tooltipValue: 40, plotValue: 50 },
        },
        {
          quarter: "2011 Q3",
          profit: { tooltipValue: 40, plotValue: 50 },
          loss: { tooltipValue: 40, plotValue: 50 },
        },
        {
          quarter: "2011 Q4",
          profit: { tooltipValue: 40, plotValue: 50 },
          loss: { tooltipValue: 40, plotValue: 50 },
        },
      ],
      dimensions: ["quarter", "profit", "loss"],
    },
  ],
  series: [
    {
      name: "profit",
      encode: { x: "quarter", y: "profit.plotValue" },
      type: "line",
      datasetIndex: 0,
    },
    {
      name: "loss",
      encode: { x: "quarter", y: "loss.plotValue" },
      type: "line",
      datasetIndex: 0,
    },
  ],
};

我试图在encode指定更深的值路径，如encode: { y: "profit.plotValue" }

但是它不起作用

它适用于像[{ profit: 40, loss: 30 }]和encode: { y: "profit" }这样的平面值

这在echarts中完全可能吗？
