Tree

Live demo

Usage

<tree :data="tree" node-text="name" layoutType="circular">
</tree>

import {tree} from 'vued3tree'

export default {
  components: {
    tree
  },
  data() {
    return {
      tree: {
        name: "father",
        children:[{
          name: "son1",
          children:[ {name: "grandson"}, {name: "grandson2"}]
        },{
          name: "son2",
          children:[ {name: "grandson3"}, {name: "grandson4"}]
        }]
      }
    }
  }
}

Props

Slots

node

Use this slot to customize the rendering of individual node.

Note that the mark-up will be rendered inside a svg element, so only svg elements are allowed here

Slot-scope:

Example:

<template #node="{data, node: {depth}, radius, isRetracted}">
  <template v-if="data.children && data.children.length">
    <path :fill="isRetracted? 'red' : 'blue'" d="M190.5..">
      <title>{{data.text}} {{depth}}</title>
    </path>
  </template>
  <template v-else>
    <circle r="6" :stroke="blue? 'blue' : 'yellow'">
      <title>{{data.text}} {{depth}}</title>
    </circle>
  </template>
</template>

popUp

Use this slot to create a pop-up, tooltip or context menu for nodes. The position of the pop-up relative to its target is defined by the popUpPlacement prop.

By default, pop-up will open when clicking on node text. This behavior can be overridden using behavioral slot. For example by using the PopUpOnTextHover component provides opening of pop-up when hovering the node test. See below for example.

Slot-scope:

Example:

<template #popUp="{data,node}">
  <div class="btn-group-vertical">
    <button @click="addFor(data)">
      <i class="fa fa-plus" aria-hidden="true"></i>
    </button>
    <button @click="remove(data, node)">
      <i class="fa fa-trash" aria-hidden="true"></i>
    </button>
  </div>
</template>

behavior

Behavior slots provide an elegant way to customize the tree behavior by receiving as slot-scope both node information (including clicked node, hovered node, ...) and actions to alter the graph accordingly.

The concept of this slot is to react to changes in node information by calling an action

By design this slot is renderless.

For more about this pattern, you can check here.

Slot-scope:

By default tree component use standardBehavior as component which provides toggle retract on node click and select the node on clicking on its text.

Example:

<tree>
  <template #behavior="{on, actions}">
    <CollapseOnClick v-bind="{on, actions}"/>
  </template>
</tree>

With CollapseOnClick component:

export default {
  props: ['on', 'actions'],

  render: () => null,

  created () {
    const {on, actions: {toggleExpandCollapse}} = this;

    on('clickedNode', ({element}) => {
      toggleExpandCollapse(element);
    })
  }
}

To display pop-up on hover, use the built-in popUpOnHoverText:

<tree>
  <template #behavior="{on, actions}">
    <popUpOnHoverText v-bind="{on, actions}"/>
  </template>
</tree>

import {tree, popUpOnHoverText} from 'vued3tree'

export default {
  components: {
    tree,
    popUpOnHoverText
  },
  //...

Events

change

• Argument : node raw data.
• Sent when the node is selected

clickedNode

• Argument : {element, data, target} where element represents the node build by D3.js, data is the node raw data and target the target DOM element.
• Sent when the node is clicked

clickOutside

• Argument: none
• Sent when mouse is clicked outside any geometry or text of the tree

clickedText

• Argument: same as mouseNodeOver
• Sent when the node text is clicked

expand

• Argument : same as clicked.
• Sent when the node is clicked and the node children are expanded

mouseOverText

• Argument: same as mouseNodeOver
• Sent when mouse hovers the node text

onNodeTextLeave

• Argument: same as mouseNodeOver
• Sent when mouse leaves the node text

retract

• Argument : same as clicked.
• Sent when the node is clicked and the node children are retracted

For all these events, the argument passed is {element, data} .

zoom

• Argument : {transform} where transform is d3.zoom transform object.
• Sent when the tree is zoomed.

Methods

Gotchas

This component is responsive and will adjust to resizing. In order for this to work properly, you must define for this component or its parent wether:

• a height or a max-height
• or a width or a max-width.

Failing to do so may result in a component whose size that will keep increasing.

Hierarchical Edge Bundling

Live demo

https://david-desmaisons.github.io/Vue.D3.tree/hierarchicalEdgeBundling

Usage

<hierarchical-edge-bundling identifier="id" :data="tree" :links="links" node-text="name"/>

import {hierarchicalEdgeBundling} from 'vued3tree'

export default {
  components: {
    hierarchicalEdgeBundling
  },
  data() {
    return {
      tree: {
        name: "father",
        children:[{
          name: "son1",
          children:[ {name: "grandson", id: 1}, {name: "grandson2", id: 2}]
        },{
          name: "son2",
          children:[ {name: "grandson3", id: 3}, {name: "grandson4", id: 4}]
        }]
      },
      links: [
        {source: 3, target: 1, type: 1},
        {source: 3, target: 4, type: 2}
      ],
      linkTypes: [
        {id: 1, name: 'depends', symmetric: true},
        {id: 2, name: 'implement', inName: 'implements', outName: 'is implemented by'},
        {id: 3, name: 'uses', inName: 'uses', outName: 'is used by'},
      ]
    }
  }
}
  //...

Props

Events

mouseNodeOver

• Argument: {element, data} where element represents the node build by D3.js and data is the node raw data.
• Sent when the node name is hovered by mouse

mouseNodeOut

• Argument: same as mouseNodeOver
• Sent when mouse leaves the node name

clickOutsideGraph

• Argument: none
• Sent when mouse is clicked outside any geometry or text of the hierarchical edge bundling

nodesComputed

• Argument: D3.js hierarchy node

• Sent when highlighted node has changed.

Data

highlightedNode

Highlighted node: when set to a node data, the corresponding node and its related links will be highlighted. If null standard display is showing.
