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。
