在vue中, 查找到有两种方法来实现词云图, 分别是echarts 和 highcharts
Echarts:
注意,wordcloud对应的echarts版本有要求:echarts-wordcloud@2 is for echarts@5 echarts-wordcloud@1 is for echarts@4
需要下载echartsjs 和 wordcloud, 全局注册引用echarts
npm install echarts@5 npm install echarts-wordcloud@2
<div class="cloud-wrap"> <div ref="cloudEl" class="cloud-box"></div> </div> <style> .cloud-wrap { width: 100%; height: 100%; } .cloud-box { width: 100%; height: 100%; } </style> <script> import wordcloud from 'echarts-wordcloud'; export default { data() { return { words:[{ id:1, content:'name' }], bgImg:'base64格式, 底色为白色', } }, mounted() { this.drawCloud(this.$refs.cloudEl, this.words); }, methods:{ drawCloud(wrapEl, data) { // let maskImage = new Image(); //可以根据图片形状生成有形状的词云图 // maskImage.src= this.bgImg; let list = this.wordCloudData.map((item) => ({ name: item.content, value: item.id })) if(list.length == 0){ list = [{name:'无',value:50}] } let myChart = echarts.init(wrapEl); let option = { tooltip: { show: true, }, // backgroundColor:'#fff', // 画布背景色 series: [ { name: "热词", type: "wordCloud", // maskImage: maskImage, // 图片形状 keepAspect: false, sizeRange: [10, 40], //画布范围,如果设置太大会出现少词(溢出屏幕) rotationRange: [0, 0], //数据翻转范围 // shape: "circle", // drawOutOfBound: true, // 超出画布的词汇是否隐藏 drawOutOfBound: false, color:"#fff", left: "center", top: "center", right: null, bottom: null, // width: "100%", height: "100%", gridSize: 8, textPadding: 10, autoSize: { enable: true, minSize: 6, }, textStyle: { normal: { fontFamily: 'sans-serif', fontWeight: 'bold', color:"#333", // 字体颜色 // color: function () { // 字体颜色 // return 'rgb(' + [ // Math.round(Math.random() * 160), // Math.round(Math.random() * 160), // Math.round(Math.random() * 160) // ].join(',') + ')'; // }, }, emphasis: { // focus: 'self', textStyle:{ shadowBlur: 10, shadowColor: "#333", } }, }, data: list, }, ], }; // maskImage.onload = function() { myChart.setOption(option, true) // }; }, } } </script>

Highcharts
下载包
npm install highcharts@7.2.1
<div class="cloud-wrap"> <div id="container" style="width: 100%;height: 100%;"></div> </div> <style> // 同上 </style> <script> import Highcharts from 'highcharts' export default { data() { return { words:[{ id:1, content:'name' }], } }, mounted() { this.dealData(); }, methods:{ dealData(){ let data = this.words.map((item,index) => ({ name: item.content, value: item.id, //weight: Math.floor(Math.random()*3+1) //控制加粗,随机数取1~3, 若需要按照接口返回的顺序, 可不随机 weight: item.id*100 })) this.drawPic(data) }, drawPic(data){ Highcharts.chart('container', { //highcharts logo credits: { enabled: false }, //导出 exporting: { enabled: false }, //提示关闭 tooltip: { enabled: false }, //颜色配置 colors:[ '#ffffff' // ,'#00c0d7','#2594ce','#de4c85', // '#ff7f46','#ffb310','#e25c52' ], //图形配置 chart: { // spacingBottom: 15, // spacingTop: 12, spacingLeft: 5, spacingRight: 5, backgroundColor: "rgba(255, 255, 255,0)", }, series: [{ type: "wordcloud",// 类型 data: data, rotation: 90,//字体不旋转 maxFontSize: 40,//最大字体 minFontSize: 14,//最小字体 style: { fontFamily: "sans-serif", fontWeight: '500' } }], }); }, } } </script>
echarts 和 highcharts 都可以在vue中实现词云图. 但是如果使用echarts的话, 需要当前的echarts进行升级或降级才能实现字体多颜色, 而highcharts则不需要. 自定义形状highcharts暂时还没探究, 需要的可以自行查找, 以后有机会的话我也会看看.
