<!-- 为 ECharts 准备一个具备大小（宽高）的 DOM -->

//方法里面第一步// 基于准备好的dom，初始化echarts实例
var myChart = this.$echarts.init(document.getElementById('box'));
// 使用刚指定的配置项和数据显示图表。
myChart.setOption(this.option);
}
},
mounted() {
// 注意：一定需要在mounted中调用才行
this.customized();
}
};
最后在main.js入口文件中 全局引入挂载
// 引入echarts
// import echarts from 'echarts'
//挂载到实例对象上
// Vue.prototype.$echarts =echarts
==================================
需要加下面两句 这个是main全局引入的
import echarts from 'echarts'
Vue.use(echarts)//全局使用echarts
<div class="echartr">
<!-- //右边环形图 -->
<div class="bargraph" id="barg2"></div>
</div>
let bargraph = echarts.init(document.getElementById('barg2'));
bargraph.setOption(this.option3);
=======================================
有时候需要加上这些代码 在页面尺寸发生改变时 随着页面改变而变大或小
mounted() {
let _this = this;
_this.$nextTick(() => {
let bargraph0 = echarts.init(_this.$refs.barg0);
bargraph0.setOption(_this.option0);
window.addEventListener("resize", bargraph0.resize);
let bargraph = echarts.init(_this.$refs.barg);
bargraph.setOption(_this.option2);
window.addEventListener("resize", bargraph.resize);
let bargraph2 = echarts.init(_this.$refs.barg2);
bargraph2.setOption(_this.option3);
window.addEventListener("resize", bargraph2.resize);
});
}
