這篇文章主要介紹了在vue中使用eacharts創(chuàng)建graph關(guān)系圖方式，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教
使用eacharts創(chuàng)建graph關(guān)系圖
在最近的工作中遇到了這個問題一開始遇到遇到問題且網(wǎng)上現(xiàn)在的教程不那么詳細于是想著自己寫一個來記錄一下。
首先想使用echarts先下載echarts包命令如下
npm install echarts --save
然后將eacharts引入到項目中，推薦在main.js引入。
import * as echarts from 'echarts';
引入完畢后將echarts掛載在原型上（僅限vue2使用）
Vue.prototype.$echarts = echarts//將echarts掛載到vue的原型上
然后再所需要的組件里創(chuàng)建一個容器
<div id="chartsBox"></div>
將echarts綁定到dom元素上
this.myEchart = this.$echarts.init(document.querySelector("#chartsBox")); //將echarts綁定到dom元素上配置echarts的配置
?this.option = {
? ? ? ? //echarts的配置文件
? ? ? ? title: {
? ? ? ? ? //title組件
? ? ? ? ? text: "Les Miserables", //顯示的文本
? ? ? ? ? subtext: "Default layout",
? ? ? ? ? top: "bottom", //組件在echarts上下的位置
? ? ? ? ? left: "right", //組件在echarts左右上的位置
? ? ? ? },
? ? ? ? tooltip: {
? ? ? ? ? //提示框組件當(dāng)鼠標移入時觸發(fā)
? ? ? ? ? show: true, //是否顯示提示框組件。
? ? ? ? ? trigger: "item", //觸發(fā)類型
?
? ? ? ? },
? ? ? ? legend: [
? ? ? ? ? //圖例組件
? ? ? ? ? {
? ? ? ? ? ? data: this.graph.categories.map(function (a) {
? ? ? ? ? ? ? //圖例所要分類的種類
? ? ? ? ? ? ? return a.name;
? ? ? ? ? ? }),
? ? ? ? ? },
? ? ? ? ],
? ? ? ? series: [
? ? ? ? ? //數(shù)據(jù)展示組件
? ? ? ? ? {
? ? ? ? ? ? name: "Les Miserables", //組件的名稱
? ? ? ? ? ? type: "graph", //組件的類行,選擇graph即關(guān)系圖
? ? ? ? ? ? layout: "force", //graph的了類型,此時為力引導(dǎo)
? ? ? ? ? ? data: this.graph.nodes, //要展示的數(shù)據(jù)
? ? ? ? ? ? links: this.graph.links, //要展示的關(guān)系線
? ? ? ? ? ? categories: this.graph.categories, //展示的所有分類
? ? ? ? ? ? roam: true, //是否可以縮放
? ? ? ? ? ? label: {
? ? ? ? ? ? ? //graph節(jié)點的標簽
? ? ? ? ? ? ? position: "right", //標簽所在的位置
? ? ? ? ? ? ? show: false, //是否默認顯示標簽
? ? ? ? ? ? },
? ? ? ? ? ? force: {
? ? ? ? ? ? ? //力引導(dǎo)的配置
? ? ? ? ? ? ? repulsion: 100, //節(jié)點之間的斥力
? ? ? ? ? ? },
? ? ? ? ? ? scaleLimit: {
? ? ? ? ? ? ? //滾輪縮放的極限控制
? ? ? ? ? ? ? max: 12, //滾輪縮放最大值
? ? ? ? ? ? ? min: 3, //滾輪縮放的最小值
? ? ? ? ? ? },
? ? ? ? ? },
? ? ? ? ],
? ? ? };通過echarts的配置文件進行渲染
this.myEchart.setOption(this.option); //通過echarts的配置文件進行渲染
以上就是全部步驟了實例代碼如下
<template>
<div id="chartsBox"></div>
</template>
<script>
export default {
name: "",
data() {
return {
myEchart: {},
