vue中使⽤词云图的实现⽰例在vue中, 查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() {
setoptionreturn {
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: t,
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(' + [
//        und(Math.random() * 160),
//        und(Math.random() * 160),
//        und(Math.random() * 160)
//    ].join(',') + ')';
// },
},
emphasis: {
// focus: 'self',
textStyle:{
shadowBlur: 10,
shadowColor: "#333",
}
},
},
data: list,
},
]
,
};
// load = function() {
myChart.setOption(option, true)
// };
},
}
}
</script>

Highcharts
下载包
npm install highcharts@7.2.1
<div class="cloud-wrap">
<div id="container" ></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: t,
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, 以后有机会的话我也会看看.
