my configuration item code.
option = {

  xAxis: {
      type: "category",
      data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
  },
  yAxis: {
      type: "value"
  },
  series: [{
      data: [820, 932, 901, 934, 1290, 1330, 1320],
      type: "line",
      smooth: true,
      markPoint: {
        symbol: "pin",
        data: [
          {coord: ["Mon", "822"], name: ""},
          // {type: "min", name: ""}
        ]
      }
  }]
};

what result do you expect? What is the error message actually seen?

I hope the boss can solve this problem, wait online, hurry! I didn"t report it wrong. It"s just that the contents of the tag are not displayed.


{coord: ["Mon", "822"], name: ""}


this is when configuring {type: "min", name:" maximum"}, the text is displayed.
