Overview

-
-

-  Vis.js comes with a flexible DataSet, which can be used to hold and
-  manipulate unstructured data and listen for changes in the data.
-  The DataSet is key/value based. Data items can be added, updated and
-  removed from the DatSet, and one can subscribe to changes in the DataSet.
-  The data in the DataSet can be filtered and ordered, and fields (like
-  dates) can be converted to a specific type. Data can be normalized when
-  appending it to the DataSet as well.
-

-
-
-
Example

-
-

-  The following example shows how to use a DataSet.
-

-
-
-// create a DataSet
-var options = {};
-var data = new vis.DataSet(options);
-
-// add items
-// note that the data items can contain different properties and data formats
-data.add([
-  {id: 1, text: 'item 1', date: new Date(2013, 6, 20), group: 1, first: true},
-  {id: 2, text: 'item 2', date: '2013-06-23', group: 2},
-  {id: 3, text: 'item 3', date: '2013-06-25', group: 2},
-  {id: 4, text: 'item 4'}
-]);
-
-// subscribe to any change in the DataSet
-data.on('*', function (event, properties, senderId) {
-  console.log('event', event, properties);
-});
-
-// update an existing item
-data.update({id: 2, group: 1});
-
-// remove an item
-data.remove(4);
-
-// get all ids
-var ids = data.getIds();
-console.log('ids', ids);
-
-// get a specific item
-var item1 = data.get(1);
-console.log('item1', item1);
-
-// retrieve a filtered subset of the data
-var items = data.get({
-  filter: function (item) {
-    return item.group == 1;
-  }
-});
-console.log('filtered items', items);
-
-// retrieve formatted items
-var items = data.get({
-  fields: ['id', 'date'],
-  type: {
-    date: 'ISODate'
-  }
-});
-console.log('formatted items', items);
-

-
-
-
-
Construction

-
-

-  A DataSet can be constructed as:
-

-
-
-var data = new vis.DataSet([data] [, options])
-

-
-

-  After construction, data can be added to the DataSet using the methods
-  add and update, as described in section
-  Data Manipulation.
-

-
-

-  The parameter data is optional and is an Array with items.
-

-
-

-  The parameter options is optional and is an object which can
-  contain the following properties:
-

-
-
-  
-    
-    
-    
-    
-  
-  
-    
-    
-    
-    
-  
-  
-    
-    
-    
-    
-  
-  
-    
-    
-    
-    
-  
-
NameTypeDefault valueDescription
fieldIdString"id"
-      The name of the field containing the id of the items.
-
-      When data is fetched from a server which uses some specific
-      field to identify items, this field name can be specified
-      in the DataSet using the option fieldId.
-      For example CouchDB uses the field
-      "_id" to identify documents.
-    
typeObject.<String, String>none
-      An object containing field names as key, and data types as
-      value. By default, the type of the properties of items are left
-      unchanged. Item properties can be normalized by specifying a
-      field type. This is useful for example to automatically convert
-      stringified dates coming from a server into JavaScript Date
-      objects. The available data types are listed in section
-      Data Types.
-    
queueObject | booleannone
-      Queue data changes ('add', 'update', 'remove') and flush them at once.
-      The queue can be flushed manually by calling
-      DataSet.flush(), or can be flushed after a configured delay
-      or maximum number of entries.
-      

-      

-      When queue is true, a queue is created
-      with default options. Options can be specified by providing an object:
-      
    
-        
  • delay: number
    
-          The queue will be flushed automatically after an inactivity of this
-          delay in milliseconds. Default value is null.
-        
  • max: number
    
-          When the queue exceeds the given maximum number
-          of entries, the queue is flushed automatically.
-          Default value is Infinity.

Data Manipulation

-
-

-  The data in a DataSet can be manipulated using the methods
-  add,
-  update,
-  and remove.
-  The DataSet can be emptied using the method
-  clear.
-

-
-
-// create a DataSet
-var data = new vis.DataSet();
-
-// add items
-data.add([
-  {id: 1, text: 'item 1'},
-  {id: 2, text: 'item 2'},
-  {id: 3, text: 'item 3'}
-]);
-
-// update an item
-data.update({id: 2, text: 'item 2 (updated)'});
-
-// remove an item
-data.remove(3);
-

-
-
Add

-
-

-  Add a data item or an array with items.
-

-
-Syntax:
-
var addedIds = DataSet.add(data [, senderId])

-
-The argument data can contain:
-
    
-  
  • 
-    An Object containing a single item to be
-    added. The item must contain an id.
-  
    • 
-  
  • 
-    An Array containing a list with items to be added. Each item must contain an id.
-  
    • 
-

-
-

-  After the items are added to the DataSet, the DataSet will
-  trigger an event add. When a senderId
-  is provided, this id will be passed with the triggered
-  event to all subscribers.
-

-
-

-  The method will throw an Error when an item with the same id
-  as any of the added items already exists.
-

-
-
Update

-
-

-  Update a data item or an array with items.
-

-
-Syntax:
-
var updatedIds = DataSet.update(data [, senderId])

-
-The argument data can contain:
-
    
-  
  • 
-    An Object containing a single item to be
-    updated. The item must contain an id.
-  
    • 
-  
  • 
-    An Array containing a list with items to be updated. Each item must contain an id.
-  
    • 
-

-
-

-  The provided properties will be merged in the existing item.
-  When an item does not exist, it will be created.
-

-
-

-  After the items are updated, the DataSet will
-  trigger an event add for the added items, and
-  an event update. When a senderId
-  is provided, this id will be passed with the triggered
-  event to all subscribers.
-

-
-
Remove

-
-

-  Remove a data item or an array with items.
-

-
-Syntax:
-
var removedIds = DataSet.remove(id [, senderId])

-
-

-  The argument id can be:
-

-
    
-  
  • 
-    A Number or String containing the id
-    of a single item to be removed.
-  
    • 
-  
  • 
-    An Object containing the item to be deleted.
-    The item will be deleted by its id.
-  
    • 
-  
  • 
-    An Array containing ids or items to be removed.
-  
    • 
-

-
-

-  The method ignores removal of non-existing items, and returns an array
-  containing the ids of the items which are actually removed from the
-  DataSet.
-

-
-

-  After the items are removed, the DataSet will
-  trigger an event remove for the removed items.
-  When a senderId is provided, this id will be passed with
-  the triggered event to all subscribers.
-

-
-
-
Clear

-
-

-  Clear the complete DataSet.
-

-
-Syntax:
-
var removedIds = DataSet.clear([senderId])

-
-

-  After the items are removed, the DataSet will
-  trigger an event remove for all removed items.
-  When a senderId is provided, this id will be passed with
-  the triggered event to all subscribers.
-

-
-
-
Data Selection

-
-

-  The DataSet contains functionality to format, filter, and sort data retrieved via the
-  methods get, getIds, forEach, and map. These methods have the following syntax:
-

-
-
-DataSet.get([id] [, options]);
-DataSet.getIds([options]);
-DataSet.forEach(callback [, options]);
-DataSet.map(callback [, options]);
-

-
-

-  Where options is an Object which can have the following
-  properties:
-

-
-

NameTypeDescription
fieldsString[ ] | Object.<String, String>
-      An array with field names, or an object with current field name and 
-      new field name that the field is returned as.
-      By default, all properties of the items are emitted.
-      When fields is defined, only the properties
-      whose name is specified in fields will be included
-      in the returned items.
-    
typeObject.<String, String>
-      An object containing field names as key, and data types as value.
-      By default, the type of the properties of an item are left
-      unchanged. When a field type is specified, this field in the
-      items will be converted to the specified type. This can be used
-      for example to convert ISO strings containing a date to a
-      JavaScript Date object, or convert strings to numbers or vice
-      versa. The available data types are listed in section
-      Data Types.
-    
filterFunctionItems can be filtered on specific properties by providing a filter
-      function. A filter function is executed for each of the items in the
-      DataSet, and is called with the item as parameter. The function must
-      return a boolean. All items for which the filter function returns
-      true will be emitted.
-      See section Data Filtering.
orderString | FunctionOrder the items by a field name or custom sort function.
returnTypeStringDetermine the type of output of the get function. Allowed values are 'Array' | 'Object'.
-          The default returnType is an Array. The Object type will return a JSON object with the ID's as keys.

-
-

-  The following example demonstrates formatting properties and filtering
-  properties from items.
-

-
-
-// create a DataSet
-var data = new vis.DataSet();
-data.add([
-  {id: 1, text: 'item 1', date: '2013-06-20', group: 1, first: true},
-  {id: 2, text: 'item 2', date: '2013-06-23', group: 2},
-  {id: 3, text: 'item 3', date: '2013-06-25', group: 2},
-  {id: 4, text: 'item 4'}
-]);
-
-// retrieve formatted items
-var items = data.get({
-  fields: ['id', 'date', 'group'],    // output the specified fields only
-  type: {
-    date: 'Date',                   // convert the date fields to Date objects
-    group: 'String'                 // convert the group fields to Strings
-  }
-});
-

-
-
Getting Data

-
-

-  Data can be retrieved from the DataSet using the method get.
-  This method can return a single item or a list with items.
-

-
-
A single item can be retrieved by its id:

-
-
-var item1 = dataset.get(1);
-

-
-
A selection of items can be retrieved by providing an array with ids:

-
-
-var items = dataset.get([1, 3, 4]); // retrieve items 1, 3, and 4
-

-
-
All items can be retrieved by simply calling get without
-  specifying an id:

-
-
-var items = dataset.get();          // retrieve all items
-

-
-
-
Data Filtering

-
-

-  Items can be filtered on specific properties by providing a filter
-  function. A filter function is executed for each of the items in the
-  DataSet, and is called with the item as parameter. The function must
-  return a boolean. All items for which the filter function returns
-  true will be emitted.
-

-
-
-// retrieve all items having a property group with value 2
-var group2 = dataset.get({
-  filter: function (item) {
-    return (item.group == 2);
-  }
-});
-
-// retrieve all items having a property balance with a value above zero
-var positiveBalance = dataset.get({
-  filter: function (item) {
-    return (item.balance > 0);
-  }
-});
-
-

-
-
-

Overview

-
-

-  A DataView offers a filtered and/or formatted view on a
-  DataSet.
-  One can subscribe on changes in a DataView, and easily get filtered or
-  formatted data without having to specify filters and field types all
-  the time.
-

-
-
Example

-
-

-  The following example shows how to use a DataView.
-

-
-
-// create a DataSet
-var data = new vis.DataSet();
-data.add([
-  {id: 1, text: 'item 1', date: new Date(2013, 6, 20), group: 1, first: true},
-  {id: 2, text: 'item 2', date: '2013-06-23', group: 2},
-  {id: 3, text: 'item 3', date: '2013-06-25', group: 2},
-  {id: 4, text: 'item 4'}
-]);
-
-// create a DataView
-// the view will only contain items having a property group with value 1,
-// and will only output fields id, text, and date.
-var view = new vis.DataView(data, {
-  filter: function (item) {
-    return (item.group == 1);
-  },
-  fields: ['id', 'text', 'date']
-});
-
-// subscribe to any change in the DataView
-view.on('*', function (event, properties, senderId) {
-  console.log('event', event, properties);
-});
-
-// update an item in the data set
-data.update({id: 2, group: 1});
-
-// get all ids in the view
-var ids = view.getIds();
-console.log('ids', ids); // will output [1, 2]
-
-// get all items in the view
-var items = view.get();
-

-
-
Construction

-
-
-

-  A DataView can be constructed as:
-

-
-
-var data = new vis.DataView(dataset, options)
-

-
-

-  where:
-

-
-
    
-  
  • 
-    dataset is a DataSet or DataView.
-  
    • 
-  
  • 
-    options is an object which can
-    contain the following properties. Note that these properties
-    are exactly the same as the properties available in methods
-    DataSet.get and DataView.get.
-
-

    NameTypeDescription
    convertObject.<String, String>
-          An object containing field names as key, and data types as value.
-          By default, the type of the properties of an item are left
-          unchanged. When a field type is specified, this field in the
-          items will be converted to the specified type. This can be used
-          for example to convert ISO strings containing a date to a
-          JavaScript Date object, or convert strings to numbers or vice
-          versa. The available data types are listed in section
-          Data Types.
-        
    fieldsString[ ] | Object.<String, String>
-          An array with field names, or an object with current field name and 
-          new field name that the field is returned as. 
-          By default, all properties of the items are emitted.
-          When fields is defined, only the properties
-          whose name is specified in fields will be included
-          in the returned items.
-        
    filterfunctionItems can be filtered on specific properties by providing a filter
-          function. A filter function is executed for each of the items in the
-          DataSet, and is called with the item as parameter. The function must
-          return a boolean. All items for which the filter function returns
-          true will be emitted.

Graph3d documentation

-
-
Overview

-

-  Graph3d is an interactive visualization chart to draw data in a three dimensional
-  graph. You can freely move and zoom in the graph by dragging and scrolling in the
-  window. Graph3d also supports animation of a graph.
-

-

-  Graph3d uses HTML canvas
-  to render graphs, and can render up to a few thousands of data points smoothly.
-

-
-
Contents

-
-
-
Example

-

-  The following code shows how to create a Graph3d and provide it with data.
-  More examples can be found in the examples directory.

Loading

-
-

-  The class name of the Graph3d is vis.Graph3d.
-  When constructing a Graph3d, an HTML DOM container must be provided to attach
-  the graph to. Optionally, data an options can be provided.
-  Data is a vis DataSet or an Array, described in
-  section Data Format.
-  Options is a name-value map in the JSON format. The available options
-  are described in section Configuration Options.
-

-
var graph = new vis.Graph3d(container [, data] [, options]);

-
-

-  Data and options can be set or changed later on using the functions
-  Graph3d.setData(data) and Graph3d.setOptions(options).
-

-
-
Data Format

-

-  Graph3d can load data from an Array, a DataSet or a DataView.
-  JSON objects are added to this DataSet by using the add() function.
-  Data points must have properties x, y, and z,
-  and can optionally have a property style and filter.
-
-

Events

-

-  Graph3d fires events after the camera position has been changed.
-  The event can be catched by creating a listener.
-  Here an example on how to catch a cameraPositionChange event.
-

-
-
-function onCameraPositionChange(event) {
-  alert('The camera position changed to:\n' +
-        'Horizontal: ' + event.horizontal + '\n' +
-        'Vertical: ' + event.vertical + '\n' +
-        'Distance: ' + event.distance);
-}
-// assuming var graph3d = new vis.Graph3d(document.getElementById('mygraph'));
-graph3d.on('cameraPositionChange', onCameraPositionChange);

vis.js documentation

-
-  

-    Vis.js is a dynamic, browser based visualization library.
-    The library is designed to be easy to use, handle large amounts
-    of dynamic data, and enable manipulation of the data.
-  

-
-  

-    The library is developed by
-    Almende B.V..
-    Vis.js runs fine on Chrome, Firefox, Opera, Safari, IE9+, and most mobile
-    browsers (with full touch support).
-  

-
-  
Components

-
-  

-    Vis.js contains of the following components:
-

-    
    • 
-    
  • 
-      DataView.
-      A filtered and/or formatted view on a DataSet.
-

-  }
-});
-
-require(['vis'], function (math) {
-  // ... load a visualization
-});
-

-
-  

-    A timeline can be instantiated as follows. Other components can be
-    created in a similar way.
-  

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

namereturnsdescription
findNode(

-              String nodeId
)		   Array   Nodes can be in clusters. Clusters can also be in clusters. This function returns and array of nodeIds showing where the node is. Example: 

-            cluster 'A' contains cluster 'B',

-            cluster 'B' contains cluster 'C',

-            cluster 'C' contains node 'fred'.

-            network.clustering.findNode('fred') will return ['A','B','C','fred'].
-        
isCluster(

-              String nodeId
)		   Boolean Returns true if the node whose ID has been supplied is a cluster.
openCluster(
  
-            String nodeId
)		               none    Opens the cluster, releases the contained nodes and edges, removing the cluster node and cluster edges.
cluster(
  
-            Object options
)		              none    The options object is explained in full below. The joinCondition function is presented with all nodes.
clusterByConnection(

-              String nodeId,

-              [Object options]

-            )		                                             none    This method looks at the provided node and makes a cluster of it and all it's connected nodes. The behaviour can be customized by proving the options object. All options of this object are explained below. The joinCondition is only presented with the connected nodes.
clusterByHubsize(

-              Number hubsize,

-              [Object options]
)		none    This method checks all nodes in the network and those with a equal or higher amount of edges than specified with the hubsize qualify. Cluster by connection is performed on each of them. The options object is described for clusterByConnection and does the same here.
clusterOutliers(

-              [Object options]
)		none    This method will cluster all nodes with 1 edge with their respective connected node.

-    

-    
Cluster options object

-    
The options object supplied to the cluster functions can contain these properties:

-    
-        
-        
-            
-        
-        
-        
-    
nameTypedescription
joinCondition(
  Object nodeOptions
)		     FunctionOptional for all but the cluster method.  The cluster module loops over all nodes that are selected to be in the cluster and calls this function with their data as argument.
-                If this function returns true, this node will be added to the cluster. You have access to all options (including the default)
-                as well as any custom fields you may have added to the node to determine whether or not to include it in the cluster. Example:
-
-var nodes = [
-  {id: 4, label: 'Node 4'},
-  {id: 5, label: 'Node 5'},
-  {id: 6, label: 'Node 6', cid:1},
-  {id: 7, label: 'Node 7', cid:1}
-]
-
-var options = {
-  joinCondition:function(nodeOptions) {
-    return nodeOptions.cid === 1;
-  }
-}
-
-network.clustering.cluster(options);
-
processProperties(
  Object nodeOptions
)		 Function   Optional.  Before creating the new cluster node, this (optional) function will be called with the properties supplied by you (clusterNodeProperties), all contained nodes and all contained edges. You can use this to update the
-                                                                                                                                properties of the cluster based on which items it contains. The function should return the properties to create the cluster node. In the example below, we ensure preservation of mass and value when forming the cluster:
-
-var options = {
-  processProperties: function (clusterOptions, childNodes, childEdges) {
-    var totalMass = 0;
-    var totalValue = 0;
-    for (var i = 0; i < childNodes.length; i++) {
-        totalMass += childNodes[i].mass;
-        totalValue = childNodes[i].value ? totalValue + childNodes[i].value : totalValue;
-    }
-    clusterOptions.mass = totalMass;
-    if (totalValue > 0) {
-      clusterOptions.value = totalValue;
-    }
-    return clusterOptions;
-  },
-}
-
clusterNodeProperties    Object     Optional.  This is an object containing the options for the cluster node. All options described in the nodes module are allowed. This allows you to style your cluster node any way you want. This is also the style object that is provided in the processProperties function for fine tuning. If undefined, default node options will be used.
clusterEdgeProperties    Object     Optional.  This is an object containing the options for the edges connected to the cluster. All options described in the edges module are allowed. Using this, you can style the edges connecting to the cluster any way you want. If none are provided, the optoins from the edges that are replaced are used. If undefined, default edge options will be used.

namereturnsdescription
getScale()      NumberReturns the current scale of the network. 1.0 is comparible to 100%, 0 is zoomed out infinitely.
getPosition()   NumberReturns the current central focus point of the camera.
fit([Object options])noneZooms out so all nodes fit on the canvas. You can supply options to customize this:
-
-{
-  nodes:[Array of nodeIds],
-  animation: { // -------------------> can be a boolean too!
-    duration: Number
-    easingFunction: String
-  }
-}
-

-            The nodes can be used to zoom to fit only specific nodes in the view. 


-            The other options are explained in the moveTo() description below.
-            All options are optional for the fit method.
-        
focus(

-               String nodeId,

-               [Object options]
)		noneYou can focus on a node with this function. What that means is the view will lock onto that node, if it is moving, the view will also move accordingly. If the view is dragged by the user, the focus is broken.
-                You can supply options to customize the effect:
-
-{
-  scale: Number,
-  offset: {x:Number, y:Number}
-  locked: boolean
-  animation: { // -------------------> can be a boolean too!
-    duration: Number
-    easingFunction: String
-  }
-}
-

-        All options except for locked are explained in the moveTo() description below. Locked denotes whether or not the view remains locked to the node once the zoom-in animation is finished. Default value is true. The options object is optional in the focus method.
moveTo(Object options)      noneYou can animate or move the camera using the moveTo method. Options are:
-
-{
-  position: {x:Number, y:Number},
-  scale: Number,
-  offset: {x:Number, y:Number}
-  animation: { // -------------------> can be a boolean too!
-    duration: Number
-    easingFunction: String
-  }
-}
-

-            The position (in canvas units!) is the position of the central focus point of the camera. 


-            The scale is the target zoomlevel. Default value is 1.0. 


-            The offset (in DOM units) is how many pixels from the center the view is focussed.  Default value is {x:0,y:0}.


-            For animation you can either use a Boolean to use it with the default options or disable it or you can define the duration (in milliseconds) and easing function manually. Available are:
-            linear, easeInQuad, easeOutQuad, easeInOutQuad, easeInCubic, easeOutCubic, easeInOutCubic, easeInQuart, easeOutQuart, easeInOutQuart, easeInQuint, easeOutQuint, easeInOutQuint. 


-            You will have to define at least a scale or a position. Otherwise, there is nothing to move to.
-        
releaseNode()noneProgramatically release the focussed node.

-
-    
Events

-    
These events are fired by the renderer and can be used to move and draw custom elements on the same canvas as the rest of the network.

Timeline documentation

-
-
Overview

-

-  The Timeline 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.
-

-

-  Timeline uses regular HTML DOM to render the timeline and items put on the
-  timeline. This allows for flexible customization using css styling.
-

-
-
Contents

-
-
Example

-

-  The following code shows how to create a Timeline and provide it with data.
-  More examples can be found in the examples directory.
-

-
-
<!DOCTYPE HTML>
-<html>
-<head>
-  <title>Timeline | Basic demo</title>
-
-  <style type="text/css">
-    body, html {
-      font-family: sans-serif;
-    }
-  </style>
-
-  <script src="../../dist/vis.js"></script>
-  <link href="../../dist/vis.css" rel="stylesheet" type="text/css" />
-</head>
-<body>
-<div id="visualization"></div>
-
-<script type="text/javascript">
-  // 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: '2013-04-20'},
-    {id: 2, content: 'item 2', start: '2013-04-14'},
-    {id: 3, content: 'item 3', start: '2013-04-18'},
-    {id: 4, content: 'item 4', start: '2013-04-16', end: '2013-04-19'},
-    {id: 5, content: 'item 5', start: '2013-04-25'},
-    {id: 6, content: 'item 6', start: '2013-04-27'}
-  ]);
-
-  // Configuration for the Timeline
-  var options = {};
-
-  // Create a Timeline
-  var timeline = new vis.Timeline(container, items, options);
-</script>
-</body>
-</html>
-

-
-
-
Loading

-

-  Install or download the vis.js library.
-  in a subfolder of your project. Include the libraries script and css files in the
-  head of your html code:
-

-
-
-<script src="vis/dist/vis.js"></script>
-<link href="vis/dist/vis.css" rel="stylesheet" type="text/css" />
-

-
-The constructor of the Timeline is vis.Timeline
-
var timeline = new vis.Timeline(container, items, options);

-or when using groups:
-
var timeline = new vis.Timeline(container, items, groups, options);

-
-The constructor accepts four parameters:
-
    
-  
  • 
-    container is the DOM element in which to create the timeline.
-  
    • 
-  
  • 
-    items is an Array containing items. The properties of an
-    item are described in section Data Format, items.
-  
  • 
-        groups is an Array containing groups. The properties of a
-        group are described in section Data Format, groups.
-    
    • 
-  
  • 
-    options is an optional Object containing a name-value map
-    with options. Options can also be set using the method
-    setOptions.
-  
    • 
-

-
-
Data Format

-
-

-  The timeline can be provided with two types of data:
-

-
    
-  
  • Items containing a set of items to be displayed in time.
    • 
-  
  • Groups containing a set of groups used to group items
-    together.
    • 
-

-
-
Items

-

-  The Timeline uses regular Arrays and Objects as data format.
-  Data items can contain the properties start,
-  end (optional), content,
-  group (optional), className (optional),
-  and style (optional).
-

-
-

-  A table is constructed as:
-

-
-
-var items = [
-  {
-    start: new Date(2010, 7, 15),
-    end: new Date(2010, 8, 2),  // end is optional
-    content: 'Trajectory A'
-    // Optional: fields 'id', 'type', 'group', 'className', 'style'
-  }
-  // more items...
-]);
-

-
-

-  The item properties are defined as:
-

classNameStringnoThis field is optional. A className can be used to give items
-      an individual css style. For example, when an item has className
-      'red', one can define a css style like:
-      
-.vis.timeline .red {
-  color: white;
-  background-color: red;
-  border-color: darkred;
-}

-      More details on how to style items can be found in the section
-      Styles.
-    
contentStringyesThe contents of the item. This can be plain text or html code.
endDate | number | string | MomentnoThe end date of the item. The end date is optional, and can be left null.

-      all items with the same group are placed on one line.
-      A vertical axis is displayed showing the groups.
-      Grouping items can be useful for example when showing availability of multiple
-      people, rooms, or other resources next to each other.

-    
idString | NumbernoAn id for the item. Using an id is not required but highly
-      recommended. An id is needed when dynamically adding, updating,
-      and removing items in a DataSet.
startDate | number | string | MomentyesThe start date of the item, for example new Date(2010,9,23).
styleStringno
-      A css text string to apply custom styling for an individual item, for
-      example "color: red; background-color: pink;".

-      same height instead of staking them on top of each other. can be ordered
-      by specifying the option subgroupOrder of a group.
-    
titleStringnoneAdd a title for the item, displayed when holding the mouse on the item.
-      The title can only contain plain text.
-    
typeString'box'The type of the item. Can be 'box' (default), 'point', 'range', or 'background'.
-      Types 'box' and 'point' need a start date, the types 'range' and 'background' needs both a start and end date.

Groups

-

-  Like the items, groups are regular JavaScript Arrays and Objects.
-  Using groups, items can be grouped together.
-  Items are filtered per group, and displayed as
-
-  Group items can contain the properties id,
-  content, and className (optional).
-

-

-  Groups can be applied to a timeline using the method setGroups or supplied in the constructor.
-  A table with groups can be created like:
-

-
-
-var groups = [
-  {
-    id: 1,
-    content: 'Group 1'
-    // Optional: a field 'className', 'style'
-  }
-  // more groups...
-]);

showMinorLabelsbooleantrueBy default, the timeline shows both minor and major date labels on the
-        time axis.
-        For example the minor labels show minutes and the major labels show hours.
-        When showMinorLabels is false, no minor labels
-        are shown. When both showMajorLabels and
-        showMinorLabels are false, no horizontal axis will be
-        visible.
stackBooleantrueIf true (default), items will be stacked on top of each other such that they do not overlap.
snapfunction | nullfunctionWhen moving items on the Timeline, they will be snapped to nice dates like full hours or days, depending on the current scale. The snap function can be replaced with a custom function, or can be set to null to disable snapping. The signature of the snap function is:
-    
function snap(date: Date, scale: string, step: number) : Date | number

-    The parameter scale can be can be 'millisecond', 'second', 'minute', 'hour', 'weekday, 'day, 'month, or 'year'. The parameter step is a number like 1, 2, 4, 5.
-    
startDate | Number | String | MomentnoneThe initial start date for the axis of the timeline.
-        If not provided, the earliest date present in the events is taken as start date.
templateFunctionnoneA template function used to generate the contents of the items. The function is called by the Timeline with an items data as argument, and must return HTML code as result. When the option template is specified, the items do not need to have a field content. See section Templates for a detailed explanation.
timeAxis.scalestringnoneSet a fixed scale for the time axis of the Timeline. Choose from 'millisecond', 'second', 'minute', 'hour', 'weekday', 'day', 'month', 'year'. Example usage:
-  
var options = {
-  timeAxis: {scale: 'minute', step: 5}
-}

-  
timeAxis.stepnumber1
-      Set a fixed step size for the time axis. Only applicable when used together with timeAxis.scale.
-      Choose for example 1, 2, 5, or 10.
typeStringnoneSpecifies the default type for the timeline items. Choose from 'box', 'point', 'range', and 'background'. Note that individual items can override this default type. If undefined, the Timeline will auto detect the type from the items data: if a start and end date is available, a 'range' will be created, and else, a 'box' is created. Items of type 'background' are not editable.
-    
widthString'100%'The width of the timeline in pixels or as a percentage.
zoomableBooleantrue
-        Specifies whether the Timeline can be zoomed by pinching or scrolling in the window.
-        Only applicable when option moveable is set true.
-    
zoomMaxNumber315360000000000Set a maximum zoom interval for the visible range in milliseconds.
-        It will not be possible to zoom out further than this maximum.
-        Default value equals about 10000 years.
-    
zoomMinNumber10Set a minimum zoom interval for the visible range in milliseconds.
-        It will not be possible to zoom in further than this minimum.

Events

-

-  Timeline fires events when changing the visible window by dragging, when
-  selecting items, and when dragging the custom time bar.
-

-
-

-  Here an example on how to listen for a select event.
-

-
-
-timeline.on('select', function (properties) {
-  alert('selected items: ' + properties.nodes);
-});
-

-
-

-  A listener can be removed via the function off:
-

-
-
-function onSelect (properties) {
-  alert('selected items: ' + properties.nodes);
-}
-
-// add event listener
-timeline.on('select', onSelect);
-
-// do stuff...
-
-// remove event listener
-timeline.off('select', onSelect);
-

-
-

-
-
Editing Items

-

-  When the Timeline is configured to be editable (both options selectable and editable are true), the user can:
-

-
    
-  
  • Select an item by clicking it, and use ctrl+click to or shift+click to select multiple items
    • 
-  
  • Move selected items by dragging them.
    • 
-  
  • Create a new item by double tapping on an empty space.
    • 
-  
  • Create a new range item by dragging on an empty space with the ctrl key down.
    • 
-  
  • Update an item by double tapping it.
    • 
-  
  • Delete a selected item by clicking the delete button on the top right.
    • 
-

-
-
Option editable accepts a boolean or an object. When editable is a boolean, all manipulation actions will be either enabled or disabled. When editable is an object, one can enable individual manipulation actions:

-
-
// enable or disable all manipulation actions
-var options = {
-  editable: true       // true or false
-};
-
-// enable or disable individual manipulation actions
-var options = {
-  editable: {
-    add: true,         // add new items by double tapping
-    updateTime: true,  // drag items horizontally
-    updateGroup: true, // drag items from one group to another
-    remove: true       // delete an item by tapping the delete button top right
-  }
-};

-
-
-

-  One can specify callback functions to validate changes made by the user. There are a number of callback functions for this purpose:
-

-
-
    
-  
  • onAdd(item, callback) Fired when a new item is about to be added. If not implemented, the item will be added with default text contents.
    • 
-  
  • onUpdate(item, callback) Fired when an item is about to be updated. This function typically has to show a dialog where the user change the item. If not implemented, nothing happens.
    • 
-  
  • onMove(item, callback) Fired when an item has been moved. If not implemented, the move action will be accepted.
    • 
-  
  • onMoving(item, callback) Fired repeatedly while an item is being moved (dragged). Can be used to adjust the items start, end, and/or group to allowed regions.
    • 
-  
  • onRemove(item, callback) Fired when an item is about to be deleted. If not implemented, the item will be always removed.
    • 
-

-
-

-  Each of the callbacks is invoked with two arguments:
-

-
    
-  
  • item: the item being manipulated
    • 
-  
  • callback: a callback function which must be invoked to report back. The callback must be invoked as callback(item | null). Here, item can contain changes to the passed item. Parameter `item` typically contains fields `content`, `start`, and optionally `end`. The type of `start` and `end` is determined by the DataSet type configuration and is `Date` by default.  When invoked as callback(null), the action will be cancelled.
    • 
-

-
-

-  Example code:
-

-
-
var options = {
-  onUpdate: function (item, callback) {
-    item.content = prompt('Edit items text:', item.content);
-    if (item.content != null) {
-      callback(item); // send back adjusted item
-    }
-    else {
-      callback(null); // cancel updating the item
-    }
-  }
-};
-

-
-A full example is available here: 08_edit_items.html.
-
-
-
Templates

-
-

-  Timeline supports templates to format item contents. Any template engine (such as handlebars or mustache) can be used, and one can also manually build HTML. In the options, one can provide a template handler. This handler is a function accepting an items data as argument, and outputs formatted HTML:
-

-
-
var options = {
-  template: function (item) {
-    var html = ... // generate HTML markup for this item
-    return html;
-  }
-};
-

-
-
Create HTML manually

-
-The HTML for an item can be created manually:
-
-
var options = {
-  template: function (item) {
-    return '<h1>' + item.header + '</h1><p>' + item.description + '</p>';
-  }
-};
-

-
-
Using a template engine

-
-Using handlebars, one can write the template in HTML:
-
-
-<script id="item-template" type="text/x-handlebars-template">
-  <h1>{{header}}</h1>
-  <p>{{description}}</p>
-</script>
-

-
-Compile the template:
-
-
-var source = document.getElementById('item-template').innerHTML;
-var template = Handlebars.compile(source);
-

-
-And then specify the template in the Timeline options
-
-
var options = {
-  template: template
-};
-

-
-
Multiple templates

-
-In order to support multiple templates, the template handler can be extended to switch between different templates, depending on a specific item property:
-
-
-var templates = {
-  template1: Handlebars.compile(...),
-  template2: Handlebars.compile(...),
-  template2: Handlebars.compile(...),
-  ...
-};
-
-var options = {
-  template: function (item) {
-    var template = templates[item.template];  // choose the right template
-    return template(item);                    // execute the template
-  }
-};
-

-
-Now the items can be extended with a property template, specifying which template to use for the item.
-
-
-
Localization

-

-  Timeline can be localized. For localization, Timeline depends largely on the localization of moment.js. Locales are not included in vis.js by default. To enable localization, moment.js must be loaded with locales. Moment.js offers a bundle named "moment-with-locales.min.js" for this and there are various alternative ways to load locales.
-

-
-

-  To set a locale for the Timeline, specify the option locale:
-

-
-
var options = {
-  locale: 'nl'
-};
-

-
-
Create a new locale

-
-To load a locale into the Timeline not supported by default, one can add a new locale to the option locales:
-
-
var options = {
-  locales: {
-    // create a new locale (text strings should be replaced with localized strings)
-    mylocale: {
-      current: 'current',
-      time: 'time',
-    }
-  },
-
-  // use the new locale
-  locale: 'mylocale'
-};
-

-
-
Available locales

-

For example, to change the border and background color of all items, include the
-  following code inside the head of your html code or in a separate stylesheet.

-
<style>
-  .vis-item {
-    border-color: orange;
-    background-color: yellow;
-  }
-</style>

Grid Backgrounds

-

-  The background grid of the time axis can be styled, for example to highlight
-  weekends or to create grids with an alternating white/lightgray background.
-

-

-  Depending on the zoom level, the grids get certain css classes attached.
-  The following classes are available:
