气泡集 BubbleSets

查看 Markdown编辑此页

概述

BubbleSets 插件通过创建气泡形状来表示集合及其关系，帮助用户直观地理解集合间的交集、并集等逻辑关系。它是一种增强数据可视化效果的工具，特别适用于展示复杂的数据集合关系。

使用场景

BubbleSets 插件主要适用于以下场景：

  • 展示集合间的关系（如交集、并集）
  • 增强数据可视化的表达能力
  • 在复杂网络图中标识特定节点或边的集合

基本用法

以下是一个简单的 BubbleSets 插件初始化示例：

const graph = new Graph({
  plugins: [
    {
      type: 'bubble-sets',
      members: ['node1', 'node2'], // 需要包裹的节点 ID 列表
      label: true, // 是否显示标签
    },
  ],
});

使用示例

基础 BubbleSets

最简单的方式是直接使用预设配置：

const graph = new Graph({
  plugins: [
    {
      type: 'bubble-sets',
      members: ['node-0', 'node-1', 'node-2', 'node-3'],
    },
  ],
});

效果如下：


import { Graph } from '@antv/g6';

const graph = new Graph({
  container: 'container',
  width: 300,
  height: 150,
  autoFit: 'center',
  data: {
    nodes: [
      {
        id: 'node-0',
        data: { cluster: 'a' },
        style: { x: 555, y: 151 },
      },
      {
        id: 'node-1',
        data: { cluster: 'a' },
        style: { x: 532, y: 323 },
      },
      {
        id: 'node-2',
        data: { cluster: 'a' },
        style: { x: 473, y: 227 },
      },
      {
        id: 'node-3',
        data: { cluster: 'a' },
        style: { x: 349, y: 212 },
      },
      {
        id: 'node-4',
        data: { cluster: 'b' },
        style: { x: 234, y: 201 },

自定义 BubbleSets 样式

const graph = new Graph({
  plugins: [
    {
      type: 'bubble-sets',
      members: ['node-0', 'node-1', 'node-2', 'node-3'],
      fill: '#7e3feb', // 气泡填充颜色
      fillOpacity: 0.1, // 填充透明度
      stroke: '#7e3feb', // 边框颜色
      strokeOpacity: 1, // 边框透明度
    },
  ],
});

效果如下：


import { Graph } from '@antv/g6';

const graph = new Graph({
  container: 'container',
  width: 300,
  height: 150,
  autoFit: 'center',
  data: {
    nodes: [
      {
        id: 'node-0',
        data: { cluster: 'a' },
        style: { x: 555, y: 151 },
      },
      {
        id: 'node-1',
        data: { cluster: 'a' },
        style: { x: 532, y: 323 },
      },
      {
        id: 'node-2',
        data: { cluster: 'a' },
        style: { x: 473, y: 227 },
      },
      {
        id: 'node-3',
        data: { cluster: 'a' },
        style: { x: 349, y: 212 },
      },
      {
        id: 'node-4',
        data: { cluster: 'b' },
        style: { x: 234, y: 201 },
      },
      {
        id: 'node-5',
        data: { cluster: 'b' },
        style: { x: 338, y: 333 },
      },
      {
        id: 'node-6',
        data: { cluster: 'b' },

      },
    ],
    edges: [
      {
        id: 'edge-0',
        source: 'node-0',
        target: 'node-2',
      },
      {
        id: 'edge-1',
        source: 'node-1',
        target: 'node-2',
      },
      {
        id: 'edge-2',
        source: 'node-2',
        target: 'node-3',
      },
      {
        id: 'edge-3',
        source: 'node-3',
        target: 'node-4',
      },
      {
        id: 'edge-4',
        source: 'node-3',
        target: 'node-5',
      },
      {
        id: 'edge-5',
        source: 'node-3',
        target: 'node-6',
      },
    ],
  },
  plugins: [
    {
      type: 'bubble-sets',
      members: ['node-0', 'node-1', 'node-2', 'node-3'],
      fill: '#7e3feb', // 气泡填充颜色
      fillOpacity: 0.1, // 填充透明度

      strokeOpacity: 1, // 边框透明度
    },
  ],
  behaviors: ['drag-canvas', 'zoom-canvas'],
});

标签配置

您可以配置标签的位置、背景、偏移量等属性，以增强可视化效果。

const graph = new Graph({
  plugins: [
    {
      type: 'bubble-sets',
      members: ['node-0', 'node-1', 'node-2', 'node-3'],
      label: true, // 显示标签
      labelPlacement: 'top', // 标签位置
      labelBackground: true, // 显示标签背景
      labelPadding: 5, // 标签内边距
    },
  ],
});

效果如下：


import { Graph } from '@antv/g6';

const graph = new Graph({
  container: 'container',
  width: 300,
  height: 150,
  autoFit: 'center',
  data: {
    nodes: [
      {
        id: 'node-0',
        data: { cluster: 'a' },

    edges: [
      {
        id: 'edge-0',
        source: 'node-0',
        target: 'node-2',

      {
        id: 'edge-1',
        source: 'node-1',
