需求：

鼠标移入：

1、容器

<div id="syscBubleChart" style="width: 700px; height: 380px; background: rgba(2, 15, 43, 0.7)" ></div>

2、data中的数据

export default {
	 data() {
    	return {
	    	plantCap: [
		        {
		          name: "2018",
		          value: "46.96",
		          num: "55236",
		          tip: "一年以上",
		          color: "#FF923F",
		        },
		        {
		          name: "2019",
		          value: "17.25",
		          num: "20293",
		          tip: "半年到一年",
		          color: "#00EA9C",
		        },
		        {
		          name: "2020",
		          value: "35.79",
		          num: "42100",
		          tip: "半年以下",
		          color: "#4F9EFD",
		        },
	      	],
		}
	}

}

3、在methods中

methods:{
initChart(){
let colors = ["rgb(148, 91, 51)", "rgb(0, 147, 103)", "rgb(52, 99, 162)"];
  // 计算数据总和  reduce
  let result = this.plantCap.reduce(
      (sum, e) => Number(sum) + Number(e.value),
        0
      );
  var datalist = [
        {
          offset: [10, 80],
          symbolSize: 80,
          opacity: 0.5,
          color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
            {
              offset: 0,
              color: "rgb(46, 42, 50, .5)",
            },
            {
              offset: 1,
              color: "rgb(148, 91, 51,.5)",
            },
          ]),
        },
        {
          offset: [38, 70],
          symbolSize: 84,
          opacity: 0.5,
          color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
            {
              offset: 0,
              color: "rgb(10, 55, 61, .5)",
            },
            {
              offset: 1,
              color: "rgb(0, 147, 103, .5)",
            },
          ]),
        },
        {
          offset: [66, 80],
          symbolSize: 90,
          opacity: 0.5,
          color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
            {
              offset: 0,
              color: "rgb(8, 44, 84, .5)",
            },
            {
              offset: 1,
              color: "rgb(52, 99, 162, .5)",
            },
          ]),
        },
      ];
        var datas = [];
      for (var i = 0; i < this.plantCap.length; i++) {
        var item = this.plantCap[i];
        var itemToStyle = datalist[i];
        datas.push({
          // name: item.name + "\n" + item.value,
          name:
            ((item.value / result) * 100).toFixed(2) +
            "%" +
            "\n" +
            "\n" +
            "\n" +
            "\n" +
            item.num +
            "人", //气泡的百分比,
          value: itemToStyle.offset,
          symbolSize: itemToStyle.symbolSize,
          label: {
            normal: {
              textStyle: {
                fontSize: 20,

                color: item.color,
                padding: [68, 0, 0, 0],

          },
        });
      }
       let option = {
        // backgroundColor: "#20203e",
        color: colors,
        grid: {
          show: false,

          trigger: "axis",
          // 图例文字颜色
          textStyle: {
            fontSize: "20",

            show: false,
            min: 0,
            max: 100,
            nameLocation: "middle",
            nameGap: 5,
          },
        ],
        yAxis: [

                formatter: "{b}",
                color: "#fff",
                textStyle: {
                  fontSize: "20",
                  fontFamily: "BoldCondensed",
                },
              },

            },
            data: datas,
          },
          {
            name: "半年到一年",

            type: "scatter",
            symbol: "circle",
            symbolSize: 120,
            label: {
              normal: {
                show: true,
                formatter: "{b}",
                color: "#fff",
                textStyle: {
                  fontSize: "20",
                  fontFamily: "BoldCondensed",
                },
              },
            },
            data: datas,
          },
          {
            name: "半年以下",
            type: "scatter",
            symbol: "circle",
            symbolSize: 120,

                color: "#fff",
                textStyle: {
                  fontSize: "20",
                  fontFamily: "BoldCondensed",
                },
              },
            },
            data: datas,
          },
        ],
      };
 let myChart = this.$echarts.init(document.getElementById("syscBubleChart"));
  myChart.setOption(option);
      window.addEventListener("resize", function () {
        myChart.resize();
      });
}
}

4、在mounted中调用

mounted() {
    this.initChart();
  },

以上
