Vue uses Echarts to display incomplete maps.

simplify the official website demo, and as a result, the map only shows the South China Sea islands and each point.

the Vue code is as follows:

drawMap () {
  let data = [
    {name: "", value: 9},
    {name: "", value: 12},
    {name: "", value: 12},
    {name: "", value: 12},
    {name: "", value: 14},
    {name: "", value: 15},
    {name: "", value: 16},
    {name: "", value: 18},
    {name: "", value: 18},
    {name: "", value: 19},
    {name: "", value: 21}
  ]
  let geoCoordMap = {

  let convertData = function (data) {
    var res = []
    for (var i = 0; i < data.length; iPP) {

      }
    }
    return res
  }
  let option = {
    tooltip: {

    geo: {

        },
        emphasis: {
          areaColor: "-sharp8c86f7"
        }
      }
    },
    series: [
      {
        name: "house",
        type: "scatter",
        coordinateSystem: "geo",
        data: convertData(data),
        symbolSize: 20,
        label: {
          normal: {

          },
          emphasis: {

        },
        itemStyle: {

            color: "-sharpf1f425"
          },
          emphasis: {
            borderColor: "-sharpfff",
            borderWidth: 1
          }
        }
      }
    ]

  }
  this.chartMap = echarts.init(document.getElementById("chartMap"))
  this.chartMap.setOption(option)
}

call this.drawMap () in mounted

I don"t know what the problem is. Try it with the Echart3 version, the same question

Mar.04,2021

it is estimated that there is no registered map file. The map file is under echarts/map , with json and js formats, introduced and registered. Take World Map as an example:

import echarts from 'echarts'
import world from 'echarts/map/json/world.json'

echarts.registerMap('world', world)

you don't have a map file, do you
