Vue引用echarts详细步骤

1、在要用的组件页加一个id：main

<!-- echart -->
    <div id="main" style="height: 200px; width: 200px"></div>
    <div>11111</div>

2、在终端执行安装echarts命令：npm install echarts

3、引用echarts（5.0版本需要加 * as）： import * as echarts from "echarts";

4、打开Apache ECharts官网：https://echarts.apache.org/examples/zh/index.html
选择自己需要的图，这里是一个雷达图，我自己调整好样式后的代码：

option = {
  radar: {
    // shape: 'circle',
    radius:"66%",
    center:["50%","42%"],
    splitNumber:8,
    splitArea:{
      areaStyle:{
        color:"rgba(127,95,132,.3)",
        opacity:1,
        shadowBlur:45,
        shadowColor: 'rgba(0, 0, 0, 0.5)',
        shadowOffsetX:0,
        shadowOffsetY :15,
      }
    },
    indicator: [
      { name: '销售', max: 6500 },
      { name: '政府', max: 16000 },
      { name: '信息技术', max: 30000 },
      { name: '客户支持', max: 38000 },
      { name: '发展', max: 52000 },
      { name: '市场', max: 25000 }
    ]
  },
    legend: {
      left:"center",
      bottom:"10",
    data: ['分配预算', '预计支出','实际支出']
  },
  series: [
    {
      type: 'radar',
      symbolSize:0,
      areaStyle:{
        normal:{
             shadowBlur:13,
             shadowColor:"rgba(0,0,0,.2)",
             shadowOffsetX:0,
             shadowOffsetY:10,
             opacity:1,
        }
      },
      data: [
         {
                value: [5000, 7000, 12000, 11000, 15000, 14000],
                name: "分配预算",
                
              },
              {
                value: [4000, 9000, 15000, 15000, 13000, 11000],
                name: "预计支出",
              },
              {
                value: [5500, 11000, 12000, 15000, 12000, 12000],
                name: "实际支出",
              },
      ]
    }
  ]
};

script完整代码如下：
可以自己调整样式，在api文档有对照解释，链接如下，可供学习与参考：https://echarts.apache.org/zh/api.html#echarts

<script>
// echarts
import * as echarts from "echarts";
export default {
  data() {
    return {
      chartDom: "",
      myChart: "",
      option: "",
    };
  },
  mounted() {
    this.$nextTick(() => {
      this.chartDom = document.getElementById("main");
      this.myChart = echarts.init(this.chartDom);
      this.initChart();
    });
  },

  methods: {
    initChart() {
      console.log(document.getElementById("main"), "----d");
      // return;
      // this.chart = echarts.init(this.$el, "macarons");

      this.option = {
        radar: {
          // shape: 'circle',
          radius: "66%",
          center: ["50%", "42%"],
          splitNumber: 8,
          splitArea: {
            areaStyle: {
              color: "rgba(127,95,132,.3)",
              opacity: 1,
              shadowBlur: 45,
              shadowColor: "rgba(0, 0, 0, 0.5)",
              shadowOffsetX: 0,
              shadowOffsetY: 15,
            },
          },
          indicator: [
            { name: "销售", max: 6500 },
            { name: "政府", max: 16000 },
            { name: "信息技术", max: 30000 },
            { name: "客户支持", max: 38000 },
            { name: "发展", max: 52000 },
            { name: "市场", max: 25000 },
          ],
        },
        legend: {
          left: "center",
          bottom: "10",
          data: ["分配预算", "预计支出", "实际支出"],
        },
        series: [
          {
            type: "radar",
            symbolSize: 0,
            areaStyle: {
              normal: {
                shadowBlur: 13,
                shadowColor: "rgba(0,0,0,.2)",
                shadowOffsetX: 0,
                shadowOffsetY: 10,
                opacity: 1,
              },
            },
            data: [
              {
                value: [5000, 7000, 12000, 11000, 15000, 14000],
                name: "分配预算",
              },
              {
                value: [4000, 9000, 15000, 15000, 13000, 11000],
                name: "预计支出",
              },
              {
                value: [5500, 11000, 12000, 15000, 12000, 12000],
                name: "实际支出",
              },
            ],
          },
        ],
      };
      this.option && this.myChart.setOption(this.option);
    },
    //
  },
};
</script>

效果如下：
