Graph2d documentation

+ +

Overview

+

+ Graph2d is an interactive visualization chart to draw data in a 2D graph. + You can freely move and zoom in the graph by dragging and scrolling in the + window. +

+

+ Graph2d uses HTML DOM and SVG for rendering. This allows for flexible + customization using css styling. +

+ +

Contents

+ + +

Example

+

+ The following code shows how to create a Graph2d and provide it with data. + More examples can be found in the examples directory. +

+  };
+  var graph2d = new vis.Graph2d(container, dataset, options);
+</script>
+</body>
+</html>
+
+
+ + +

Loading

+ +

+ The class name of the Graph2d is vis.Graph2d. + When constructing a Graph2d, 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. + Groups is a vis DataSet containing groups. The available options and the method of construction + are described in section Data Format. +

+
var graph = new vis.Graph2d(container [, data] [, options] [,groups]);
+ +

+ Data, options and groups can be set or changed later on using the functions + Graph2d.setData(data), Graph2d.setOptions(options) and Graph2d.setGroups(groups). +

+ +

Data Format

+

+ Graph2d 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. +

+ Graph2d can be provided with two types of data: +

+
    +
  • Items containing a set of points to be displayed.
    • +
  • Groups containing a set of groups used to group items + together. All items belonging to a group will be drawn as a single graph.
    • +
+ +

Items

+ +
+var items = [
+    {x: '2014-06-13', y: 30, group: 0},
+    {x: '2014-06-14', y: 10, group: 0},
+    {x: '2014-06-15', y: 15, group: 1},
+    {x: '2014-06-16', y: 30, group: 1},
+    {x: '2014-06-17', y: 10, group: 1},
+    {x: '2014-06-18', y: 15, group: 1}
+];
+
+ +
Name
+ + + + + + + + + + + + + + + + + + + + + + + + + +
NameTypeRequiredDescription
xnumberyesLocation on the x-axis.
ynumberyesLocation on the y-axis.
groupnumber | stringnoThe ID of the group this point belongs to.
+ +

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 individual graphs. Groups can contain the properties id, + content, className (optional) and options (optional). +

+

+ Groups can be applied to a timeline using the method setGroups. + A table with groups can be created like: +

+ +
+var groups = new vis.DataSet();
+groups.add({
+    id: 1,
+    content: 'Group 1'
+    // Optional: a field 'className'
+    // Optional: options
+  })
+groups.add({
+  // more groups...
+});
+
+ + +

+ Groups can have the following properties: +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
NameTypeRequiredDescription
idString | NumberyesAn id for the group. The group will display all items having a + property group which matches the id + of the group.
contentStringyesThe contents of the group. This can be plain text or html code.
classNameStringnoThis field is optional. A className can be used to give groups + an individual css style. +
optionsJSON objectnoThis field is optional. The options can be used to give a group a specific draw style. + Any options that are colored green in the Configuration Options can be used as options here. +
+ +

Configuration Options

+ +

Graph2d Options

+ +Options can be used to customize the Graph2d to your purposes. These options can be passed to the Graph2d object either in +the constructor, or by the setOptions function. + +
+var options = {
+    width:  '100%',
+    height: '400px',
+    style: 'surface'
+};
+
+ +The options colored in green can also be used as options for the groups. All options are optional. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
NameTypeDefaultDescription
yAxisOrientationString'left'This defines with which axis, left or right, the graph is coupled. Example 5 shows groups with different Y axis. If no groups are coupled + with an axis, it will not be shown.
defaultGroupString'default'This is the label for the default, ungrouped items when shown in a legend.
sortBooleantrueThis determines if the items are sorted automatically. + They are sorted by the x value. If sort is enabled, more optimizations are possible, increasing the performance.
samplingBooleantrueIf sampling is enabled, graph2D will automatically determine the amount of points per pixel. + If there are more than 1 point per pixel, not all points will be drawn. Disabling sampling will cause a decrease in performance.
graphHeightNumber | String'400px'This is the height of the graph SVG canvas. + If it is larger than the height of the outer frame, you can drag up and down + the vertical direction as well as the usual horizontal direction.
shadedBoolean | ObjectfalseToggle a shaded area with the default settings.
shaded.enabledBooleanfalseThis toggles the shading.
shaded.orientationString'bottom'This determines if the shaded area is at the bottom or at the top of the curve. The options are 'bottom' or 'top'.
styleString'line'This allows the user to define if this should be a linegraph or a barchart. The options are: 'line' or 'bar'.
barChart.widthNumber50The width of the bars.
barChart.alignString'center'The alignment of the bars with regards to the coordinate. The options are 'left', 'right' or 'center'.
catmullRomBoolean | ObjecttrueToggle the interpolation with the default settings. For more customization use the JSON format.
catmullRom.enabledBooleantrueToggle the interpolation.
catmullRom.parametrizationString'centripetal'Define the type of parametrizaion. Example 7 shows the different methods. The options are 'centripetal' (best results), 'chordal' and 'uniform'. Uniform is the computationally cheapest variant. + If catmullRom is disabled, linear interpolation is used.
drawPointsBoolean | ObjecttrueToggle the drawing of the datapoints with the default settings.
drawPoints.enabledBooleantrueToggle the drawing of the datapoints.
drawPoints.sizeNumber6Determine the size at which the data points are drawn.
drawPoints.styleString'square'Determine the shape of the data points. The options are 'square' or 'circle'.
dataAxis.showMinorLabelsBooleantrueToggle the drawing of the minor labels on the Y axis.
dataAxis.showMajorLabelsBooleantrueToggle the drawing of the major labels on the Y axis.
dataAxis.iconsBooleanfalseToggle the drawing of automatically generated icons the Y axis.
dataAxis.widthNumber | String'40px'Set the (minimal) width of the yAxis. The axis will resize to accomodate the labels of the Y values.
dataAxis.visibleBooleantrueShow or hide the data axis.
legendBooleanfalseToggle the legend with the default settings.
legend.enabledBooleanfalseToggle the legend.
legend.iconsBooleantrueShow automatically generated icons on the legend.

Methods

+

+ The Graph2d supports the following methods. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
MethodReturn TypeDescription
clear([what])none + Clear the Graph2d. An object can be passed specifying which sections to clear: items, groups, + and/or options. By Default, items, groups and options are cleared, i.e. what = {items: true, groups: true, options: true}. Example usage: + +
Graph2d.clear();                // clear items, groups, and options
+Graph2d.clear({options: true}); // clear options only
+
+
destroy()noneDestroy the Graph2d. The Graph2d is removed from memory. all DOM elements and event listeners are cleaned up. +
getCustomTime()DateRetrieve the custom time. Only applicable when the option showCustomTime is true. +
setCustomTime(time)noneAdjust the custom time bar. Only applicable when the option showCustomTime is true. time is a Date object. +
getWindow()ObjectGet the current visible window. Returns an object with properties start: Date and end: Date.
on(event, callback)noneCreate an event listener. The callback function is invoked every time the event is triggered. Avialable events: rangechange, rangechanged, select. The callback function is invoked as callback(properties), where properties is an object containing event specific properties. See section Events for more information.
off(event, callback)noneRemove an event listener created before via function on(event, callback). See section Events for more information.
redraw()noneForce a redraw of the Graph2d. Can be useful to manually redraw when option autoResize=false. +
setGroups(groups)noneSet a data set with groups for the Graph2d. + groups can be an Array with Objects, + a DataSet, or a DataView. For each of the groups, the items of the + Graph2d are filtered on the property group, which + must correspond with the id of the group. +
setItems(items)noneSet a data set with items for the Graph2d. + items can be an Array with Objects, + a DataSet, or a DataView. +
setOptions(options)noneSet or update options. It is possible to change any option of the Graph2d at any time. You can for example switch orientation on the fly. +
setWindow(start, end)noneSet the current visible window. The parameters start and end can be a Date, Number, or String. If the parameter value of start or end is null, the parameter will be left unchanged.
+ + +

Events

+

+ Graph2d 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 rangeChanged event. +

+ +
+Graph2d.on('select', function (properties) {
+  alert('selected items: ' + properties.nodes);
+});
+
+ +

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

+ +
+function onChange (properties) {
+  alert('changed!');
+}
+
+// add event listener
+Graph2d.on('rangechanged', onChange);
+
+// do stuff...
+
+// remove event listener
+Graph2d.off('rangechanged', onChange);
+
+ + +

+ The following events are available. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    Network documentation

    + +

    Overview

    +

    + Network is a visualization to display networks and networks consisting of nodes + and edges. The visualization is easy to use and supports custom shapes, + styles, colors, sizes, images, and more. +

    + +

    + The network visualization works smooth on any modern browser for up to a + few thousand nodes and edges. To handle a larger amount of nodes, Network + has clustering support. Network uses + HTML canvas + for rendering. +

    + +

    + Every dataset is different. Nodes can have different sizes based on content, interconnectivity can be high or low etc. Because of this, network has a special option + that the user can use to explore which settings may be good for you. Use configurePhysics as described in the Physics section or by + example 25. +

    + +

    + To get started with Network, install or download the + vis.js library. +

    + + +

    Contents

    + + + +

    Example

    +

    + Here a basic network example. Note that unlike the + Timeline, the Network does not need the vis.css + file. +

    + +

    + More examples can be found in the + examples directory. +

    + + +

    Loading

    +

    + Install or download the vis.js library. + in a subfolder of your project. Include the library script in the head of your html code: +

    + +
    +<script type="text/javascript" src="vis/dist/vis.js"></script>
+
    + + +The constructor of the Network is vis.Network. +
    var network = new vis.Network(container, data, options);
    + +The constructor accepts three parameters: +
      +
    • + container is the DOM element in which to create the network. +
      • +
    • + data is an Object containing properties nodes and + edges, which both contain an array with objects. + Optionally, data may contain an options object. + The parameter data is optional, data can also be set using + the method setData. Section Data Format + describes the data object. +
      • +
    • + options is an optional Object containing a name-value map + with options. Options can also be set using the method + setOptions. + Section Configuration Options + describes the available options. +
      • +
    + +

    Data format

    +

    + The data parameter of the Network constructor is an object + which can contain different types of data. + The following properties are supported in the data object: +

    + +
      +
    • + A property pair nodes and edges, + both containing an Array with objects. The data formats are described + in the sections Nodes and Edges. + Example: +
      +var data = {
+  nodes: [...],
+  edges: [...]
+};
+
      +
      • +
    • + A property dot, + containing a string with data in the + DOT language. + DOT support is described in section DOT_language. + + Example: +
      +var data = {
+  dot: '...'
+};
+
      +
      • +
    • + A property options, + containing an object with global options. + Options can be provided as third parameter in the network constructor + as well. Section Configuration Options + describes the available options. + +
      • +
    + +

    Nodes

    + +

    + Nodes typically have an id and label. + A node must contain at least a property id. + Nodes can have extra properties, used to define the shape and style of the + nodes. +

    + +

    + A JavaScript Array with nodes is constructed like: +

    +
    +var nodes = [
+  {
+    id: 1,
+    label: 'Node 1'
+  },
+  // ... more nodes
+];
+
    +Alternatively, a vis DataSet can also be used: +
    +var nodes = new vis.DataSet();
+nodes.add([
+    {id: '1', label: 'Node 1'},
+    {id: '2', label: 'Node 2'},
+    {id: '3', label: 'Node 3'},
+    {id: '4', label: 'Node 4'},
+    // ... more nodes
+]);
+
    +When using a DataSet, the network is automatically updating to changes in the DataSet. + +

    + Nodes support the following properties: +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    ynumbernoVertical position in pixels. + The vertical position of the node will be fixed. + The horizontal position x may remain undefined.
    + + +

    Edges

    + +

    + Edges are connections between nodes. + An edge must at least contain properties from and + to, both referring to the id of a node. + Edges can have extra properties, used to define the type and style. +

    + +

    + A JavaScript Array with edges is constructed as: +

    +
    +var edges = [
+  {
+    from: 1,
+    to: 3
+  },
+  // ... more edges
+];
+
    +Alternatively, a vis DataSet can also be used: +
    +var edges = new vis.DataSet();
+edges.add([
+    {from: '1', to: '2'},
+    {from: '1', to: '3'},
+    {from: '2', to: '4'},
+    {from: '2', to: '5'},
+    // ... more edges
+]);
+
    +When using a DataSet, the network is automatically updating to changes in the DataSet. + +

    + Edges support the following properties: +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    toNumber | StringyesThe id of a node where the edge ends. The type must correspond with + the type of the node id's. This is normally a number, but can be any + type.
    valuenumbernoA value for the edge. + The width of the edges will be scaled automatically from minimum to + maximum value. + If a width is provided for the edge too, it will override the + width calculated from the value.
    widthnumbernoWidth of the line in pixels. The width will + override a specified value, if a value is + specified too.
    + + + +

    DOT language

    + +

    + Network supports data in the + DOT language. + To provide data in the DOT language, the data object must contain + a property dot with a String containing the data. +

    + +

    + Example usage: +

    + +
    +// provide data in the DOT language
+var data = {
+  dot: 'dinetwork {1 -> 1 -> 2; 2 -> 3; 2 -- 4; 2 -> 1 }'
+};
+
+// create a network
+var network = new vis.Network(container, data);
+
    + + + +

    Configuration options

    + +

    + Options can be used to customize the network. Options are defined as a JSON object. + All options are optional. +

    + +
    +var options = {
+  width:  '100%',
+  height: '400px',
+  edges: {
+    color: 'red',
+    width: 2
+  }
+};
+
    + +

    + The following options are available. +

The smoothCurves require support nodes and those positions are not stored. In order + to speed up the initialization of the network by using storePosition() and loading the nodes with the stored positions, the freezeForStabilization option freezes all nodes that have been supplied with + an x and y position in place during the stabilization. That way only the support nodes for the smooth curves have to stabilize, greatly speeding up the stabilization process with cached positions. +
    groupsObjectnoneIt is possible to specify custom styles for groups. + Each node assigned a group gets the specified style. + See Groups configuration for an overview of the available styles + and an example. +
    heightString"400px"The height of the network in pixels or as a percentage.

    Nodes configuration

    +

    + Nodes can be configured with different styles and shapes. To configure nodes, provide an object named nodes in the options for the Network. +

    + +

    + For example to give the nodes a custom color, shape, and size: +

    +
    +var options = {
+  // ...
+  nodes: {
+    color: {
+      background: 'white',
+      border: 'red',
+      highlight: {
+        background: 'pink',
+        border: 'red'
+      }
+    },
+    shape: 'star',
+    radius: 24
+  }
+};
+
    + +

    + The following options are available for nodes. These options must be created + inside an object nodes in the networks options object.

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    + + +

    Edges configuration

    + +

    + Edges can be configured with different length and styling. To configure edges, provide an object named edges in the options for the Network. +

    + +

    + For example to set the width of all edges to 2 pixels and give them a red color: +

    +
    +var options = {
+  // ...
+  edges: {
+    color: 'red',
+    width: 2
+  }
+};
+
    + +

    + The following options are available for edges. These options must be created + inside an object edges in the networks options object. +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    widthNumber1The default width of a edge.
    widthSelectionMultiplierNumber2Determines the thickness scaling of an selected edge. This is applied when an edge, or a node connected to it, is selected.
    + +

    Groups configuration

    + +

    It is possible to specify custom styles for groups of nodes. + Each node having assigned to this group gets the specified style. + The options groups is an object containing one or multiple groups, + identified by a unique string, the groupname. +

    +

    + A group can have the following styles: +

    + +
    +var options = {
+  // ...
+
+  groups: {
+    mygroup: {
+      shape: 'circle',
+      color: {
+        border: 'black',
+        background: 'white',
+        highlight: {
+          border: 'yellow',
+          background: 'orange'
+        }
+      }
+      fontColor: 'red',
+      fontSize: 18
+    }
+    // add more groups here
+  }
+};
+
+var nodes = [
+  {id: 1, label: 'Node 1'},                    // will get the default style
+  {id: 2, label: 'Node 2', group: 'mygroup'},  // will get the style from 'mygroup'
+  // ... more nodes
+];
+
    + + +

    The following styles are available for groups:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    Physics

    +

    + The original simulation method was based on particel physics with a repulsion field (potential) around each node, + and the edges were modelled as springs. The new system employed the Barnes-Hut gravitational simulation model. The edges are still modelled as springs. + To unify the physics system, the damping, repulsion distance and edge length have been combined in an physics option. To retain good behaviour, both the old repulsion model and the Barnes-Hut model have their own parameters. + If no options for the physics system are supplied, the Barnes-Hut method will be used with the default parameters. If you want to customize the physics system easily, you can use the configurePhysics option.
    + When using the hierarchical display option, hierarchicalRepulsion is automatically used as the physics solver. Similarly, if you use the hierarchicalRepulsion physics option, hierarchical display is automatically turned on with default settings. + +

    Note: if the behaviour of your network is not the way you want it, use configurePhysics as described below or by example 25.

    +

    +
    +// These variables must be defined in an options object named physics.

    Configuration:

    +Every dataset is different. Nodes can have different sizes based on content, interconnectivity can be high or low etc. Because of this, network has a special option +that the user can use to explore which settings may be good for him or her. This is ment to be used during the development phase when you are implementing vis.js. Once you have found +settings you are happy with, you can supply them to network using the physics options as described above. + +On start, the default settings will be loaded. Keep in mind that selecting the hierarchical simulation mode disables smooth curves. These will not be enabled again afterwards. +
    +var options = {
+    configurePhysics:true
+}
+
    +

    Data manipulation

    +

    + By using the data manipulation feature of the network you can dynamically create nodes, connect nodes with edges, edit nodes or delete nodes and edges. + The toolbar is fully HTML and CSS so the user can style this to their preference. To control the behaviour of the data manipulation, users can insert custom functions + into the data manipulation process. For example, an injected function can show an detailed pop-up when a user wants to add a node. In example 21, + two functions have been injected into the add and edit functionality. This is described in more detail in the next subsection. To correctly display the manipulation icons, the vis.css file must be included. + The user is free to alter or overload the CSS classes but without them the navigation icons are not visible. +

    +
    +// These variables must be defined in an options object named dataManipulation.
+// If a variable is not supplied, the default value is used.
+var options = {
+    dataManipulation: {
+      enabled: false,
+      initiallyVisible: false
+    }
+}
+// OR to just load the module with default values:
+var options: {
+    dataManipulation: true
+}
+
    + + + + + + + + + + + + + + + + + + + + +
    NameTypeDefaultDescription
    enabledBooleanfalseEnabling or disabling of the data manipulation toolbar. If it is initially hidden, an edit button appears in the top left corner.
    initiallyVisibleBooleanfalseInitially hide or show the data manipulation toolbar.
    + +

    Data manipulation: custom functionality

    +

    + Users can insert custom functions into the add node, edit node, connect nodes, and delete selected operations. This is done by supplying them in the options. + If the callback is NOT called, nothing happens. Example 21 has two working examples + for the add and edit functions. The data the user is supplied with in these functions has been described in the code below. + For the add data, you can add any and all options that are accepted for node creation as described above. The same goes for edit, however only the fields described + in the code below contain information on the selected node. The callback for connect accepts any options that are used for edge creation. Only the callback for delete selected + requires the same data structure that is supplied to the user.

    + If there is no injected function supplied for the edit operation, the button will not be shown in the toolbar. +

    +
    +// If a variable is not supplied, the default value is used.
+var options: {
+    dataManipulation: true,
+    onAdd: function(data,callback) {

+};
+
    +

    + Because the interface elements are CSS and HTML, the user will have to correct for size changes of the canvas. To facilitate this, a new event has been added called resize. + A function can be bound to this event. This function is supplied with the new widht and height of the canvas. The CSS can then be updated accordingly. + An code snippet from example 21 is shown below. +

    +
    +network.on("resize", function(params) {console.log(params.width,params.height)});
+
    + +

    Clustering

    +

    + The network now supports dynamic clustering of nodes. This allows a user to view a very large dataset (> 50.000 nodes) without + sacrificing performance. When loading a large dataset, the nodes are clustered initially (this may take a small while) to have a + responsive visualization to work with. The clustering is both outside-in and inside-out. Outside-in means that nodes with only one + connection will be contained, or clustered, in the node it is connected to. Inside-out clustering first determines which nodes are hubs. + Hubs are defined as the nodes with the top 3% highest amount of connections (assuming normal distribution). These hubs then "grow", meaning + they contain the nodes they are connected to within themselves. The edges that were connected to the nodes that are absorbed will be reconnected to the cluster. +
    +
    + A cluster is just a node that has references to the nodes and edges it contains. It has an internal counter to keep track of its size, which is then used + to calculate the required forces. The contained nodes are removed from the global nodes index, greatly speeding up the system. +
    +
    + The clustering has the following user-configurable settings. The default values have been tested with the Network examples and work well. + The default state for clustering is off. +

    + +
    +// These variables must be defined in an options object named clustering.
+// If a variable is not supplied, the default value is used.
+var options = {
+    clustering: {
+      initialMaxNodes: 100,
+      clusterThreshold:500,
+      reduceToNodes:300,
+      chainThreshold: 0.4,
+      clusterEdgeThreshold: 20,
+      sectorThreshold: 100,

    NameTypeDefaultDescription
    initialMaxNodesNumber100If the initial amount of nodes is larger than this value, clustering starts until the total number of nodes is less than this value.
    clusterThresholdNumber500While zooming in and out, clusters can open up. Once there are more than absoluteMaxNumberOfNodes nodes, + clustering starts until reduceToMaxNumberOfNodes nodes are left. This is done to ensure performance is continuously fluid.
    reduceToNodesNumber300While zooming in and out, clusters can open up. Once there are more than absoluteMaxNumberOfNodes nodes, + clustering starts until reduceToMaxNumberOfNodes nodes are left. This is done to ensure performance is continiously fluid.
    chainThresholdNumber0.4Because of the clustering methods used, long chains of nodes can be formed. To reduce these chains, this threshold is used. + A chainThreshold of 0.4 means that no more than 40% of all nodes are allowed to be a chain node (two connections). + If there are more, they are clustered together.
    clusterEdgeThresholdNumber20This is the absolute edge length threshold in pixels. If the edge is smaller on screen (that means zooming out reduces this length) + the node will be clustered. This is triggered when zooming out.
    sectorThresholdInteger50If a cluster larger than sectorThreshold is opened, a seperate instance called a sector, will be created. All the simulation of + nodes outside of this instance will be paused. This is to maintain performance and clarity when examining large clusters. + A sector is collapsed when zooming out far enough. Also, when opening a cluster, if this cluster is smaller than this value, it is fully unpacked.
    screenSizeThresholdNumber0.2When zooming in, the clusters become bigger. A screenSizeThreshold of 0.2 means that if the width or height of this cluster + becomes bigger than 20% of the width or height of the canvas, the cluster is opened. If a sector has been created, if the sector is smaller than + 20%, we collapse this sector.
    fontSizeMultiplierNumber4.0This parameter denotes the increase in fontSize of the cluster when a single node is added to it.
    maxFontSizeNumber1000This parameter denotes the largest allowed font size. If the font becomes too large, some browsers experience problems displaying this.
    forceAmplificationNumber0.6This factor is used to calculate the increase of the repulsive force of a cluster. It is calculated by the following + formula: repulsingForce *= 1 + (clusterSize * forceAmplification).
    distanceAmplificationNumber0.2This factor is used to calculate the increase in effective range of the repulsive force of the cluster. + A larger cluster has a longer range. It is calculated by the following + formula: minDistance *= 1 + (clusterSize * distanceAmplification).
    edgeGrowthNumber20This factor determines the elongation of edges connected to a cluster.
    nodeScaling.widthNumber10This factor determines how much the width of a cluster increases in pixels per added node.
    nodeScaling.heightNumber10This factor determines how much the height of a cluster increases in pixels per added node.
    nodeScaling.radiusNumber10This factor determines how much the radius of a cluster increases in pixels per added node.
    maxNodeSizeIncrementsNumber600This limits the size clusters can grow to. The default value, 600, implies that if a cluster contains more than 600 nodes, it will no longer grow.
    activeAreaBoxSizeNumber100Imagine a square with an edge length of activeAreaBoxSize pixels around your cursor. + If a cluster is in this box as you zoom in, the cluster can be opened in a seperate sector. + This is regardless of the zoom level.
    clusterLevelDifferenceNumber2At every clustering session, Network will check if the difference between cluster levels is + acceptable. When a cluster is formed when zooming out, that is one cluster level. + If you zoom out further and it encompasses more nodes, that is another level. For example: + If the highest level of your network at any given time is 3, nodes that have not clustered or + have clustered only once will join their neighbour with the lowest cluster level.
    + + +

    + Network has a menu with navigation controls, which is disabled by default. + It can be configured with the following settings. To correctly display the navigation icons, the vis.css file must be included. + The user is free to alter or overload the CSS classes but without them the navigation icons are not visible. +

    + +
    +// use of navigation controls
+var options: {
+  navigation: true
+}
+
+
    + +

    Keyboard navigation

    +

    + The network can be navigated using shortcut keys. + The default state for the keyboard navigation is off. The predefined keys can be found in the example 20_navigation.html. +

    Hierarchical layout

    +

    + The network can be used to display nodes in a hierarchical way. This can be determined automatically, based on the amount of edges connected to each node, or defined by the user. + If the user wants to manually determine the hierarchy, each node has to be supplied with a level (from 0 being heighest to n). The automatic method + is shown in example 23 and the user-defined method is shown in example 24. + This layout method does not support smooth curves or clustering. It automatically turns these features off. +

    MethodReturn TypeDescription
    getSelection()Array of idsReturns an array with the ids of the selected nodes. + Returns an empty array if no nodes are selected. + The selections are not ordered. +
    focusOnNode(nodeId, [zoomLevel])noneThis function will move the view to center on the specified node. An optional zoomLevel can be passed where 1.0 is 100%, between 0.0 and 1.0 is zooming out and > 1.0 is zooming in. Generally, close to 1.0 is sufficient. + If this argument is not passed the view will only move, not zoom. +
    storePosition()noneThis will put the X and Y positions of all nodes in the dataset. It will also include allowedToMoveX and allowedToMoveY with the correct values. + You can use this to stablize your network once, then save the positions in a database so the next time you load the nodes, stabilization will be near instantaneous. +
    DOMtoCanvas(pos)objectThis function converts DOM coordinates to coordinates on the canvas. Input and output are in the form of {x:xpos,y:ypos}. The DOM values are relative to the network container. +
    canvasToDOM(pos)objectThis function converts canvas coordinates to coordinates on the DOM. Input and output are in the form of {x:xpos,y:ypos}. The DOM values are relative to the network container. +
    on(event, callback)noneCreate an event listener. The callback function is invoked every time the event is triggered. Avialable events: select. The callback function is invoked as callback(properties), where properties is an object containing event specific properties. See section Events for more information.
    off(event, callback)noneRemove an event listener created before via function on(event, callback). See section Events for more information.
    redraw()noneRedraw the network. Useful when the layout of the webpage changed.
    setData(data,[disableStart])noneLoads data. Parameter data is an object containing + nodes, edges, and options. Parameters nodes, edges are an Array. + Options is a name-value map and is optional. Parameter disableStart is + an optional Boolean and can disable the start of the simulation that would begin at the end + of this function by default. +
    setOptions(options)noneSet options for the network. The available options are described in + the section Configuration Options. +
    selectNodes(selection, [highlightEdges])noneSelect nodes. + selection is an array with ids of nodes to be selected. + The array selection can contain zero or multiple ids. + Example usage: network.selectNodes([3, 5]); will select + nodes with id 3 and 5. The highlisghEdges boolean can be used to automatically select the edges connected to the node. +
    selectEdges(selection)noneSelect Edges. + selection is an array with ids of edges to be selected. + The array selection can contain zero or multiple ids. + Example usage: network.selectEdges([3, 5]); will select + edges with id 3 and 5. +
    setSelection(selection)noneSelect nodes [deprecated]. + selection is an array with ids of nodes to be selected. + The array selection can contain zero or multiple ids. + Example usage: network.setSelection([3, 5]); will select + nodes with id 3 and 5. +
    setSize(width, height)noneParameters width and height are strings, + containing a new size for the visualization. Size can be provided in pixels + or in percentages.
    zoomExtent()noneScales the network so all the nodes are in center view.
    + +

    Events

    +

    + Network fires events after one or multiple nodes are selected or deselected. + The event can be catched by creating a listener. +

    + +

    + Here an example on how to catch a select event. +

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

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

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

    + The following events are available. +

        Graph2d | Interpolation

        +
        + The Graph2d makes use of Catmull-Rom spline interpolation. + The user can configure these per group, or globally. In this example we show all 4 possiblities. The differences are in the parametrization of + the curves. The options are uniform, chordal and centripetal. Alternatively you can disable the Catmull-Rom interpolation and + a linear interpolation will be used. The centripetal parametrization produces the best result (no self intersection, yet follows the line closely) and is therefore the default setting. +

        + For both the centripetal and chordal parametrization, the distances between the points have to be calculated and this makes these methods computationally intensive + if there are very many points. The uniform parametrization still has to do transformations, though it does not have to calculate the distance between point. Finally, the + linear interpolation is the fastest method. For more on the Catmull-Rom method, C. Yuksel et al. have an interesting paper titled ″On the parametrization of Catmull-Rom Curves″. +

        Graph2d | Scrolling and Sorting

        +
        + You can determine the height of the Graph2d seperately from the height of the frame. If the graphHeight + is defined, and the height is not, the frame will auto-scale to accommodate the graphHeight. If the height + is defined as well, the user can scroll up and down vertically as well as horizontally to view the graph. +

        + Vertical scrolling is planned, though not yet available. The graphHeight also does not conform if only the height is defined. +

        + You can manually disable the automatic sorting of the datapoints by using the sort option. However, doing so does reduce the optimization + of the drawing so if you have a lot of points, keep sort turned on for the best results. +
