echarts提示警告There is a chart instance already initialized on the dom.

1、其实每次初始化之前判断下有没有就行了，已经存在就进行销毁，然后重新初始化

if (this.chartBox != null && this.chartBox != "" && this.chartBox != undefined) {this.chartBox.dispose() //销毁
}

在data里面声明

    data() {return {chartBox: null};},

this.chartBox = this.$echarts.ElementById("statistical-chart"));
const option = {}
this.chartBox.setOption(option);
// 根据页面大小自动响应图表大小
window.addEventListener("resize", function () {size();
});
