第一步 下载echarts
npm install echarts – save

第二步 引入echarts
在main.js中加入import * as echarts from “echarts”;

第三步 用着你需要的页面上

 <el-col :span="8" v-for="(item, index) in list" :key="index">
        <div class="myChart" :style="{ height: '300px' }"></div>
      </el-col>

list: [
        {
          id: 1,
          value: 70,
          name: "CPU利用率",
        },
        {
          id: 2,
          value: 50,
          name: "内存利用率",
        },
        {
          id: 3,
          value: 60,
          name: "硬盘利用率",
        },
      ],

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

  methods: {
    drawLine() {
      var echarts = require("echarts");
      var roseCharts = document.getElementsByClassName("myChart"); // 对应地使用ByClassName
      for (var i = 0; i < roseCharts.length; i++) {
        // 通过for循环，在相同class的dom内绘制元素
        var myChart = echarts.init(roseCharts[i]);
        myChart.setOption({
          series: [
            {
              type: "gauge",
              axisLine: {
                lineStyle: {
                  width: 30,
                  color: [
                    [0.3, "#67e0e3"],
                    [0.7, "#37a2da"],
                    [1, "#fd666d"],
                  ],
                },
              },
              pointer: {
                itemStyle: {
                  color: "auto",
                },
              },
              axisTick: {
                distance: -30,
                length: 8,
                lineStyle: {
                  color: "#fff",
                  width: 2,
                },
              },
              splitLine: {
                distance: -30,
                length: 30,
                lineStyle: {
                  color: "#fff",
                  width: 4,
                },
              },
              axisLabel: {
                color: "auto",
                distance: 40,
                fontSize: 14,
              },
              detail: {
                valueAnimation: true,
                formatter: "{value}%",
                color: "auto",
                fontSize: 16,
              },
              data: [
                {
                  value: this.list[i].value,
                  name: this.list[i].name,
                },
              ],
            },
          ],
