<h1>Graph3d</h1>
|
|
|
|
<h2 id="Overview">Overview</h2>
|
|
<p>
|
|
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.
|
|
</p>
|
|
<p>
|
|
Graph3d uses <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Canvas">HTML canvas</a>
|
|
to render graphs, and can render up to a few thousands of data points smoothly.

The class name of the Graph3d is <code>vis.Graph3d</code>.
|
|
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 <code>DataSet</code> or an <code>Array</code>, described in
|
|
section <a href="#Data_Format">Data Format</a>.
|
|
Options is a name-value map in the JSON format. The available options
|
|
are described in section <a href="#Configuration_Options">Configuration Options</a>.

|
|
<pre class="prettyprint lang-js">var graph = new vis.Graph3d(container [, data] [, options]);</pre>
|
|
|
|
<p>
|
|
Data and options can be set or changed later on using the functions
|
|
<code>Graph3d.setData(data)</code> and <code>Graph3d.setOptions(options)</code>.
|
|
</p>
|
|
|
|
<h2 id="Data_Format">Data Format</h2>
|
|
<p>
|
|
Graph3d can load data from an <code>Array</code>, a <code>DataSet</code> or a <code>DataView</code>.
|
|
JSON objects are added to this DataSet by using the <code>add()</code> function.
|
|
Data points must have properties <code>x</code>, <code>y</code>, and <code>z</code>,
|
|
and can optionally have a property <code>style</code> and <code>filter</code>.
|
|

<h3>Definition</h3>

Parameter <code>vertical</code> is a value in radians between 0 and 0.5*Pi.

Parameter <code>distance</code> is the (normalized) distance from the

Parameter <code>horizontal</code> is a value in radians and can have any
|
|
value (but normally in the range of 0 and 2*Pi).
|
|
Parameter <code>vertical</code> is a value in radians between 0 and 0.5*Pi.
|
|
Parameter <code>distance</code> is the (normalized) distance from the
|
|
camera to the center of the graph, in the range of 0.71 to 5.0. A
|
|
larger distance puts the graph further away, making it smaller.

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 <code>cameraPositionChange</code> event.
|
|
</p>
|

'Vertical: ' + event.vertical + '\n' +
|
