Vue.js入门（五）---在vue中使用echarts词云

本文主要是介绍Vue.js入门（五）---在vue中使用echarts词云，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

效果

安装

在vue项目中安装echarts和词云

npm install echarts
npm install echarts-wordcloud

引入echarts和词云

main.js中加入

import echarts from 'echarts'
Vue.prototype.$echarts = echarts

创建一个vuewordcloud.vue

这个名字任意取哈

指定一个div

<template><div id="mywordcloud" :style="{width: '100%', height: '300px'}" :data="worddata"></div>
</template>

<script>import echarts from "echarts";import "echarts-wordcloud/dist/echarts-wordcloud";import "echarts-wordcloud/dist/echarts-wordcloud.min";export default {name: "VueWordCloud",data () {return {msg: 'Welcome to Your Vue.js App',worddata: [{name: "十九大精神",value: 15000},{name: "两学一做",value: 10081},{name: "中华民族",value: 9386},{name: "马克思主义",value: 7500},{name: "民族复兴",value: 7500},{name: "社会主义制度",value: 6500},{name: "国防白皮书",value: 6500},{name: "创新",value: 6000},{name: "民主革命",value: 4500},{name: "文化强国",value: 3800},{name: "国家主权",value: 3000},{name: "伟大复兴",value: 2500},{name: "领土完整",value: 2300},{name: "安全",value: 2000},{name: "从严治党",value: 1900},{name: "现代化经济体系",value: 1800},{name: "国防动员",value: 1700},{name: "信息化战争",value: 1600},{name: "局部战争",value: 1500},{name: "教育",value: 1200},{name: "中国梦",value: 1100},{name: "孙子兵法",value: 900},{name: "一国两制",value: 800},{name: "特色社会主义思想",value: 700},]}},mounted(){this.initChart();},methods: {initChart() {this.chart = echarts.init(document.getElementById("mywordcloud"));console.log('lll');const option = {title: {text: "热爱祖国",x: "center"},backgroundColor: "#fff",// tooltip: {//   pointFormat: "{series.name}: <b>{point.percentage:.1f}%</b>"// },series: [{type: "wordCloud",//用来调整词之间的距离gridSize: 10,//用来调整字的大小范围// Text size range which the value in data will be mapped to.// Default to have minimum 12px and maximum 60px size.sizeRange: [14, 60],// Text rotation range and step in degree.
