依旧直接上代码～

首先安装引入Echarts，我是直接把Echarts挂到VUE全局变量上了

//引入echarts
import Vue from 'vue';
import echarts from 'echarts';
Vue.prototype.$echarts = echarts;

<template>
 <div class="demo-container">
  <div ref="chart_wrap" class="chart_wrap"></div>
 </div>
</template>
<script>
export default {
 name: "demo",
 computed: {},
 data() {
  return {
   seriesData: []
  };
 },
 created() {},
 mounted() {
  this.initCharts();
  setTimeout(() => {
   this.seriesData.push({
    name: "销量",
    type: "bar",
    data: [5, 20, 36, 10, 10, 20]
   });
  }, 5000);
 },
 watch: {
  seriesData(val, oldVal) {
   console.log(1111, val, oldVal);
   this.setOptions(val);
  }
 },
 methods: {
  initCharts() {
   this.chart = this.$echarts.init(this.$refs.chart_wrap);
   this.setOptions();
  },
  setOptions(series) {
   console.log(22222,this.chart,series);
   this.chart.setOption({
    title: {
     text: "ECharts 入门示例"
    },
    tooltip: {},
    legend: {
     data: ["销量"]
    },
    xAxis: {
     data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
    },
    yAxis: {},
    series: series
   });
  }
 }
};
</script>
<style rel="stylesheet/scss" lang="scss" scoped>
.chart_wrap {
 height: 400px;
}
</style>

补充知识：echarts-循环生成图

1、问题背景

利用for循环生产多个气泡图，并且每个气泡都可以点击

2、实现源码

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>echarts-循环生成图</title>
		<link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png">
		<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery.min.js">

3、实现结果

以上这篇在vue中使用Echarts利用watch做动态数据渲染操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
