一文详解Vue如何整合Echarts实现可视化界面

pnpm install echarts --save

// 全局引入相关包
import * as echarts from "echarts";
// 开启echarts
Vue.prototype.$echarts = echarts;

<div class="box-pie" style="height: 400px" ref="chart"></div>

data(){
    return {
      chart:null,
      // 配置可视化图形
      option:  {
        title: {
          text: 'Referer of a Website',
          subtext: 'Fake Data',
          left: 'center'
        },
        tooltip: {
          trigger: 'item'
        },
        legend: {
          orient: 'vertical',
          left: 'left'
        },
        series: [
          {
            name: 'Access From',
            type: 'pie',
            radius: '50%',
            data: [

            emphasis: {

                shadowOffsetX: 0,
                shadowColor: 'rgba(0, 0, 0, 0.5)'
              }
            }
          }
        ]

  },
  methods:{
    getPage() {
      // 引用chart并初始化
      this.chart = this.$echarts.init(this.$refs.chart);
      // 使用刚指定的配置项和数据显示图表。
      this.chart.setOption(this.option);
    }
