echarts 柱状图数据渲染问题

Question

拿到后台返回的数据如下：
data: {
2020: {llastYearMap: [{num: 8, name: "苹果"}]}
2021: {lastYearMap: [{num: 9, name: "苹果"}]}
2022: {nowYearMap: [{num: 5, name: "香蕉"}]}
}
下标年份对应的柱状图x轴坐标，如何把对应的年份里面的数据渲染到对应的年份页面上

Answer 1

看看 echarts api吧数据处理成 它要的格式就行

option = {
  xAxis: {
    type: 'category',
    data: ["2020","2021","2022"]
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [8,9,5],
      type: 'bar'
    }
  ]
};
