<template>

</template>
 
<script>
import * as echarts from 'echarts';
 
export default {
  data() {
    return {
      myChart: null
    };
  },
  mounted() {
    this.initChart()
    window.addEventListener('resize', this.handleResize);
  },
  beforeDestroy() {
    window.removeEventListener('resize', this.handleResize);
    if (this.myChart) {
      this.myChart.dispose(); // 清理图表实例
    }
  },
  methods: {
    handleResize() {
      if (this.myChart) {
        this.myChart.resize();
      }
    },
    initChart(){
        this.myChart = echarts.init(this.$refs.chart);
         this.myChart.setOption({
      // ... ECharts 配置项
    });
    }
  }
};
