全局安装echarts
npm i echarts --save
将echarts绑定在原型上(main.js文件中)
import * as echarts from 'echarts';
Vue.prototype.$echarts = echarts;
准备画布
<template>
<div ref="openingChart" style="height: 600px;"></div>
</template>
<script>
import china from "../store/china.json";
export default {
methods: {
initCharts() {
// 初始化中国地图
this.$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>
地图配置option
option = {
// 地图背景色

map: 'china',

trigger: 'item',
// 自定义提示框的内容
},
