Vue 中循环渲染多个相同 echarts 图表,并传入不同的数据_vue里如何给相同的echart图标传进去不同的数据显示在不同元素内

在开发过程中我们常常需要，在一个页面中使用相同的图表来展示同级别的多个事物（如：同级别的多个不同id的仓库、同级别的多个不同id的设备等）。

例如:

 
<template>
  <div class="projectCost">
    <div class='overviewModel'> 
      <div class='one'  v-for="(item,index) in levelNameList" :key="index">
        <div class="roseChart" :id='forId(index)'></div> 
        <p class='title'>{{item.levelName}}</p>
        <div class='list'>
            <echarts-list 
            v-for="(el, i) in item.boilers"
            :key="i"
            :color="colorList[i]"
            :data="el"></echarts-list>
        </div>
      </div>
    </div>
  </div>
</template>
 
 
 
<script>
import EchartsList from './EchartList'
import { echartsFont } from "@/utils/util"; 
export default {
  props:{
    levelNameList:{   //父组件传递过来的数据
      type: Array,
      default: () => {return []}
    }
  },
  components: {EchartsList},
  data(){
    return {
        colorList: [
            "#0a9aea",
            "#FFC100",
            "#e50ec2",
            "#4fdd14",
            "#0780ed",
        ],
        getId: [],
    }
  },
  mounted(){
    //每一个echarts都做到自适应
    window.addEventListener("resize", () => {
        this.getId && this.getId.forEach((item,index) => {
            this.getId[index].resize()
        });
    });
  },
  methods:{
    forId(index) {
      return 'roseChart' + index
    },
    drawRose(){

        for(var i = 0;i < this.levelNameList.length;i++ ){

              title: {

                  text: "{a|" + this.levelNameList[i].boilers.reduce((pre, cur) => {return pre + cur.value*1},0) + "}\n{c|" + "总数" + "}",
