# vis-timeline



![example chart](docs/img/timeline.png)



The Timeline/Graph2D is an interactive visualization chart to visualize data in time. The data items can take place on a single date, or have a start and end date (a range). You can freely move and zoom in the timeline by dragging and scrolling in the Timeline. Items can be created, edited, and deleted in the timeline. The time scale on the axis is adjusted automatically, and supports scales ranging from milliseconds to years.

## Install



Install via npm:



    $ npm install vis-timeline



## Example



A basic example on loading a Timeline is shown below. More examples can be

found in the [examples directory](https://github.com/visjs/vis-timeline/tree/master/examples/)

of the project.



```html



  Timeline

  

  

  

    #visualization {

      width: 600px;

      height: 400px;

      border: 1px solid lightgray;

    }

  






  // DOM element where the Timeline will be attached

  var container = document.getElementById('visualization');



  // Create a DataSet (allows two way data-binding)

  var items = new vis.DataSet([

    {id: 1, content: 'item 1', start: '2014-04-20'},

    {id: 2, content: 'item 2', start: '2014-04-14'},

    {id: 3, content: 'item 3', start: '2014-04-18'},

    {id: 4, content: 'item 4', start: '2014-04-16', end: '2014-04-19'},

    {id: 5, content: 'item 5', start: '2014-04-25'},

    {id: 6, content: 'item 6', start: '2014-04-27', type: 'point'}

  ]);



  // Configuration for the Timeline

  var options = {};



  // Create a Timeline

  var timeline = new vis.Timeline(container, items, options);



```



## Builds



There are four builds provided at the moment.



### Standalone build



```html



```



```javascript

import { Timeline } from "vis-timeline/standalone";

```



This has no dependencies and therefore is great for things like MWEs but has

more issues with interoperability and bundle bloat. For more information see the

following [example](https://visjs.github.io/vis-timeline/examples/timeline/standalone-build.html).



### Peer build



```html



```



```javascript

import { Timeline } from "vis-timeline/peer";

```



For this build to work you have to load Vis Data and Moment (including locales

except English) packages yourself. The advantage here is that it works well with

other packages. For more information see the following [example](https://visjs.github.io/vis-timeline/examples/timeline/peer-build.html).



### ESNext build



```html



```



```javascript

import { Timeline } from "vis-timeline/esnext";

```



This is the same as the peer build but without any bundled dependencies or

pollyfills. It's indented to be used with bundlers like Rollup or Webpack which

will fetch the dependencies, prevent duplicate dependencies in the bundle, use

transpilers to add necessary polyfills etc.



### Legacy build



```html



```



```javascript

import { Timeline } from "vis-timeline";

```



This is solely kept for backwards compatibility. It is deprecated and will be

removed in case of URLs and replaced by the peer build in case of

Node.js/bundlers. Don't use this, please.



## Build



To build the library from source, clone the project from github



    $ git clone git://github.com/visjs/vis-timeline.git



The source code uses the module style of node (require and module.exports) to

organize dependencies. To install all dependencies and build the library,

run `npm install` in the root of the project.



    $ cd vis-timeline

    $ npm install



Then, the project can be build running:



    $ npm run build



### Excluding external dependencies



External dependencies such as moment, hammerjs can be excluded in the build by running:



    $ npm run build -- -e [comma separated module names]



Example:



    $ npm run build -- -e moment,hammerjs



## Test



To test the library, install the project dependencies once:



    $ npm install



Then run the tests:



    $ npm run test



## Contribute



Contributions to the vis.js library are very welcome! We can't do this alone!
