vue使用echarts实现地图的方法详解

npm i echarts --save

import * as echarts from 'echarts';
Vue.prototype.$echarts = echarts;

<template>
  <div ref="openingChart" style="height: 600px;"></div>
</template>

<script>
import china from "../store/china.json";
export default {
	methods: {
		initCharts() {
			   // 初始化中国地图
		      this.$echarts.registerMap("china", china);
		      // 获取dom节点
		      let openingChart= this.$echarts.init(this.$refs.openingChart);
		      // option配置写在最下面的
		      openingChart.setOption(option);
		      window.addEventListener("resize", () => {
		        openingBankChart.resize();
		      });
		}
	},
	mounted() {
		this.initCharts();
	}
}
</script>
