- (end code)
-
- Parameters:
-
- onBeforeCompute(node) - This method is called right before performing all computations and animations. The selected <Graph.Node> is passed as parameter.
- onAfterCompute() - This method is triggered after all animations or computations ended.
- onCreateLabel(domElement, node) - This method receives a new label DIV element as first parameter, and the corresponding <Graph.Node> as second parameter. This method will only be called once for each label. This method is useful when adding events or styles to the labels used by the JIT.
- onPlaceLabel(domElement, node) - This method receives a label DIV element as first parameter and the corresponding <Graph.Node> as second parameter. This method is called each time a label has been placed in the visualization, for example at each step of an animation, and thus it allows you to update the labels properties, such as size or position. Note that onPlaceLabel will be triggered after updating the labels positions. That means that, for example, the left and top css properties are already updated to match the nodes positions. Width and height properties are not set however.
- onBeforePlotNode(node) - This method is triggered right before plotting each <Graph.Node>. This method is useful for changing a node style right before plotting it.
- onAfterPlotNode(node) - This method is triggered right after plotting each <Graph.Node>.
- onBeforePlotLine(adj) - This method is triggered right before plotting a <Graph.Adjacence>. This method is useful for adding some styles to a particular edge before being plotted.
- onAfterPlotLine(adj) - This method is triggered right after plotting a <Graph.Adjacence>.
- onBeforeRemoveNode(node) - This method is triggered right before removing each <Graph.Node>.
-
- *Used in <ST>, <TM.Base> and <Icicle> visualizations*
-
- request(nodeId, level, onComplete) - This method is used for buffering information into the visualization. When clicking on an empty node, the visualization will make a request for this node's subtrees, specifying a given level for this subtree (defined by _levelsToShow_). Once the request is completed, the onComplete callback should be called with the given result. This is useful to provide on-demand information into the visualizations withought having to load the entire information from start. The parameters used by this method are _nodeId_, which is the id of the root of the subtree to request, _level_ which is the depth of the subtree to be requested (0 would mean just the root node). _onComplete_ is an object having the callback method _onComplete.onComplete(json)_ that should be called once the json has been retrieved.

- Class: Canvas
-
- A canvas widget used by all visualizations. The canvas object can be accessed by doing *viz.canvas*. If you want to
- know more about <Canvas> options take a look at <Options.Canvas>.
-
- A canvas widget is a set of DOM elements that wrap the native canvas DOM Element providing a consistent API and behavior
- across all browsers. It can also include Elements to add DOM (SVG or HTML) label support to all visualizations.
-
- Example:
-
- Suppose we have this HTML
-
- (start code xml)
- <div id="infovis"></div>
- (end code)
-
- Now we create a new Visualization
-
- (start code js)
- var viz = new $jit.Viz({
- //Where to inject the canvas. Any div container will do.
- 'injectInto':'infovis',
- //width and height for canvas.
- //Default's to the container offsetWidth and Height.
- 'width': 900,
- 'height':500
- });
- (end code)
-
- The generated HTML will look like this
-
- (start code xml)
- <div id="infovis">
- <div id="infovis-canvaswidget" style="position:relative;">
- <canvas id="infovis-canvas" width=900 height=500
- style="position:absolute; top:0; left:0; width:900px; height:500px;" />
- <div id="infovis-label"
- style="overflow:visible; position:absolute; top:0; left:0; width:900px; height:0px">
- </div>
- </div>
- </div>
- (end code)
-
- As you can see, the generated HTML consists of a canvas DOM Element of id *infovis-canvas* and a div label container
- of id *infovis-label*, wrapped in a main div container of id *infovis-canvaswidget*.

-
- Helpers are objects that contain rendering primitives (like rectangles, ellipses, etc), for plotting nodes and edges.
- Helpers also contain implementations of the *contains* method, a method returning a boolean indicating whether the mouse
- position is over the rendered shape.
-
- Helpers are very useful when implementing new NodeTypes, since you can access them through *this.nodeHelper* and
- *this.edgeHelper* <Graph.Plot> properties, providing you with simple primitives and mouse-position check functions.
-
- Example:
- (start code js)
- //implement a new node type
- $jit.Viz.Plot.NodeTypes.implement({
- 'customNodeType': {
- 'render': function(node, canvas) {
- this.nodeHelper.circle.render ...
- },
- 'contains': function(node, pos) {
- this.nodeHelper.circle.contains ...
- }
- }
- });
- //implement an edge type
- $jit.Viz.Plot.EdgeTypes.implement({
- 'customNodeType': {
- 'render': function(node, canvas) {
- this.edgeHelper.circle.render ...
- },
- //optional
- 'contains': function(node, pos) {
- this.edgeHelper.circle.contains ...
- }

- /*
- Method: loadJSON
-
- Loads a JSON structure to the visualization. The JSON structure can be a JSON *tree* or *graph* structure.
-
- A JSON tree or graph structure consists of nodes, each having as properties
-
- id - (string) A unique identifier for the node
- name - (string) A node's name
- data - (object) The data optional property contains a hash (i.e {})
- where you can store all the information you want about this node.
-
- For JSON *Tree* structures, there's an extra optional property *children* of type Array which contains the node's children.
-
- Example:
-
- (start code js)
- var json = {
- "id": "aUniqueIdentifier",
- "name": "usually a nodes name",
- "data": {
- "some key": "some value",
- "some other key": "some other value"
- },
- "children": [ *other nodes or empty* ]
- };
- (end code)
-
- JSON *Graph* structures consist of an array of nodes, each specifying the nodes to which the current node is connected.
- For JSON *Graph* structures, the *children* property is replaced by the *adjacencies* property.
-
- There are two types of *Graph* structures, *simple* and *extended* graph structures.
-
- For *simple* Graph structures, the adjacencies property contains an array of strings, each specifying the
- id of the node connected to the main node.
-
- Example:
-
- (start code js)
- var json = [
- {
- "id": "aUniqueIdentifier",
- "name": "usually a nodes name",
- "data": {
- "some key": "some value",
- "some other key": "some other value"
- },
- "adjacencies": ["anotherUniqueIdentifier", "yetAnotherUniqueIdentifier", 'etc']
- },
-
- 'other nodes go here...'
- ];
- (end code)
-
- For *extended Graph structures*, the adjacencies property contains an array of Adjacency objects that have as properties
-
- nodeTo - (string) The other node connected by this adjacency.
- data - (object) A data property, where we can store custom key/value information.
-
- Example:
-
- (start code js)
- var json = [
- {
- "id": "aUniqueIdentifier",
- "name": "usually a nodes name",
- "data": {
- "some key": "some value",
- "some other key": "some other value"
- },
- "adjacencies": [
- {
- nodeTo:"aNodeId",
- data: {} //put whatever you want here
- },
- 'other adjacencies go here...'
- },
-
- 'other nodes go here...'
- ];
- (end code)
-
- About the data property:
-
- As described before, you can store custom data in the *data* property of JSON *nodes* and *adjacencies*.
- You can use almost any string as key for the data object. Some keys though are reserved by the toolkit, and
- have special meanings. This is the case for keys starting with a dollar sign, for example, *$width*.
-
- For JSON *node* objects, adding dollar prefixed properties that match the names of the options defined in
- <Options.Node> will override the general value for that option with that particular value. For this to work
- however, you do have to set *overridable = true* in <Options.Node>.
-
- The same thing is true for JSON adjacencies. Dollar prefixed data properties will alter values set in <Options.Edge>
- if <Options.Edge> has *overridable = true*.
-
- When loading JSON data into TreeMaps, the *data* property must contain a value for the *$area* key,
- since this is the value which will be taken into account when creating the layout.
- The same thing goes for the *$color* parameter.
-
- In JSON Nodes you can use also *$label-* prefixed properties to refer to <Options.Label> properties. For example,
- *$label-size* will refer to <Options.Label> size property. Also, in JSON nodes and adjacencies you can set
- canvas specific properties individually by using the *$canvas-* prefix. For example, *$canvas-shadowBlur* will refer
- to the *shadowBlur* property.
-
- These properties can also be accessed after loading the JSON data from <Graph.Nodes> and <Graph.Adjacences>
- by using <Accessors>. For more information take a look at the <Graph> and <Accessors> documentation.
-
- Finally, these properties can also be used to create advanced animations like with <Options.NodeStyles>. For more
- information about creating animations please take a look at the <Graph.Plot> and <Graph.Plot.animate> documentation.

- Method: computeIncremental
-
- Performs the Force Directed algorithm incrementally.
-
- Description:
-
- ForceDirected algorithms can perform many computations and lead to JavaScript taking too much time to complete.
- This method splits the algorithm into smaller parts allowing the user to track the evolution of the algorithm and
- avoiding browser messages such as "This script is taking too long to complete".
-
- Parameters:
-
- opt - (object) The object properties are described below
-
- iter - (number) Default's *20*. Split the algorithm into pieces of _iter_ iterations. For example, if the _iterations_ configuration property
- of your <ForceDirected> class is 100, then you could set _iter_ to 20 to split the main algorithm into 5 smaller pieces.
-
- property - (string) Default's *end*. Whether to update starting, current or ending node positions. Possible values are 'end', 'start', 'current'.
- You can also set an array of these properties. If you'd like to keep the current node positions but to perform these
- computations for final animation positions then you can just choose 'end'.
-
- onStep - (function) A callback function called when each "small part" of the algorithm completed. This function gets as first formal
- parameter a percentage value.
-
- onComplete - A callback function called when the algorithm completed.
-
- Example:
-
- In this example I calculate the end positions and then animate the graph to those positions
-
- (start code js)
- var fd = new $jit.ForceDirected(...);
- fd.computeIncremental({
- iter: 20,
- property: 'end',
- onStep: function(perc) {
- Log.write("loading " + perc + "%");
- },
- onComplete: function() {
- Log.write("done");
- fd.animate();
- }
- });
