Vue2项目中使用AntV X6 自定义节点绘制组织树

1.安装X6组件库

npm install @antv/x6 –save

2.页面引入X6

import { Graph, Cell, Node, Color, Dom, Shape } from '@antv/x6';

3.实现自定义节点组织树代码

<template>
	<div class="app-container home">
		<div class="leighhs">
			<div class="glydgs">
				<div v-show="Steps === 1" id="container"></div>
				<glydInfo :getNode="getNode" v-show="Steps === 2"></glydInfo>
			
			</div>
			
			<div class="back" @click="back">
				<img src="../../assets/images/home_glyd/back.png" alt="">
			</div>
		</div>
	</div>
</template>
