ECharts 柱状排名图 柱子上方显示文字与图标

直接上干货！

效果如下：

代码如下：

methods: 中的方法

initChart() {
  let that = this;
  const fontColor = '#00D8FE'
  this.chart = this.$echarts.init(this.$refs.chart);//this.chart是data() {return {chart: null}}中创建的属性
  var option = {
    grid: {
      //柱状图位置
      top: "18%",
      left: "5%",
      right: "4%",
      bottom: "5%",
      containLabel: true,
    },
    // 柱图的标题文字
    //   title: {
    //     text: '平均游览时长：' + this.averageTime + '小时',
    //     textStyle: {
    //         align: 'left',
    //         color: '#18F6FF',
    //         fontSize: that.$base.nowSize(14),
