8.自适应resize

resizeChart() { this.echart ? this.echart.resize() : '' }
mounted() { //resize 改变图表尺寸，在容器大小发生改变时需要手动调用（因为侧边栏是可以收缩的，所以这里图表根据是否收缩来改变图表尺寸）
window.addEventListener('resize', this.resizeChart) },
//销毁 防止内存泄漏destroyed() { window.removeEventListener('resize', this.resizeChart) }

chartInit() {
      this.chart = echarts.init(this.$refs["chart"]);
    },
    resize() {
      this.chart.resize();
    },
