### Installation

```
npm install --save @recognizerhd/vue2vis-graph2d vis-data moment
```

or

```
yarn add @recognizerhd/vue2vis-graph2d vis-data moment
```

## Usage

Declare the component

```javascript
Vue.component("graph2d", vue2vis.Graph2d);
```

Add the component in the template.

```html
<body>
  <div id="app">
    <graph2d ref="graph2d" :items="items" :groups="groups" :options="options">
    </graph2d>
  </div>
</body>
```

Add groups, items and options in your observed data or computed.

```javascript
new Vue({
  el: "#app",
  data() {
    return {
      groups: [
        {
          id: 0,
          content: "Group 1"
        }
      ],
      items: [
        {
          x: "2014-06-13",
          y: 30,
          group: 0
        }
      ],
      options: {
        editable: true
      }
    };
  }
});
```

Additional info can be found on [Visjs Graph2d documentation](https://visjs.github.io/vis-timeline/docs/graph2d/)

Here is a basic working demo with item generation:

You can also create items or group labels as Vue Components:

## Events

### Component Events

By default all Vis events are emitted by your component. You can subscribe to a subset by passing an array in the prop `events` [Visjs event](https://visjs.github.io/vis-timeline/docs/graph2d/#Events).

```html
<body>
  <div id="app">
    <graph2d
      ref="graph2d"
      :items="items"
      :groups="groups"
      :options="options"
      :events="['click', 'changed']"
      @click="myClickCallback"
      @changed="myChangedCallback"
    >
    </graph2d>
  </div>
</body>
```

### Data Events

When you pass an Array of data object, it is converted internally as a DataSet.
An event with the DataSet object will be fired at mounted. It's name will be prepend with the prop name (Ex: `items-mounted`, `groups-mounted`). You could use it to interact with the DataSet.

All the [Visjs DataSet event](https://visjs.github.io/vis-data/data/dataset.html#Events) will be prepened the same fashion (`items-add`, `items-remove`, `items-update`). For example, pushing a new object to the `items` prop will fire a `items-add` event with the following payload:

```javascript
{
  event: 'add',
  properties: {
    items: [7],
  },
  senderId: null,
}
```

#### Advanced

You can also manage your own data bindings by passing your own DataSet or DataView instead of an Array.

```javascript
import { DataSet } from "vis-data";

new Vue({
  el: "#app",
  data() {
    return {
      groups: new DataSet([
        {
          id: 0,
          content: "Group 1"
        }
      ]),
      items: new DataSet([
        {
          id: 0,
          group: 0,
          start: new Date(),
          content: "Item 1"
        }
      ]),
      options: {
        editable: true
      }
    };
  }
});
```
