<p>If true, fixed nodes are aligned to the nearest grid position on the drag end event. You can pin nodes, when <code>pinMode</code> is set to true or by delivering nodes with the attribute “fixed” set to true and “x” and “y” attributes for the position. If you have already fixed nodes on your graph you can also set this attribute at runtime and resume the force. Needs a <code>resume</code> call to take into effect:</p>

<p>If true, the graph is refreshed automatically. This makes only sense when running as APEX plugin - here you have the SQL queries for loading new data with AJAX. If you run your code standalone, you have to provide new data as a parameter in the start or render method and therefore you have to use your own auto refresh logic. No <code>render</code> or <code>resume</code> call needed to take into effect:</p>

<div class="description">
<p>This text is used as the link target, when a node has a LINK attribute.</p>
<p>There are three special keywords: “none”, “nodeID” and “domContainerID”. If you use “none”, the link is opened in the same window/tab where your graph is currently shown. If you use “nodeID”, the ID of the currently clicked node is used as the target attribute, this means - you get one window/tab for each node in your graph - when you click a second time on the same node, the window/tab is reused. The same with the keyword “domContainerID” - you get one window/tab for each graph on your page - when you click a second time on the same node, the window/tab is reused.</p>
<p>Anything else is not interpreted - your given text is simply used as the target attribute of the link. This is also the case for the second option in the customize wizard called “_blank”. If you use this, then each click on a node opens in a new window/tab. You are not restricted to use only the predefined select options. It is up to you to overwrite the value in your configuration object. As an example: If you want to have always the same window/tab for each click on a node, then simply provide a text here, that fit your needs e.g. “myOwnWindowName”.</p>

<p>This method starts the graph. You can configure your graph with all the available methods, but without the <code>start</code> method your changes will NOT take into effect.</p>
<p>You can pass new data (see included-sample-data) to the <code>start</code> method. Data can be a XML string, JSON string or JavaScript object (JSON). If you use the APEX plugin, then the <code>start</code> method internally does the AJAX call to your Oracle database, but you can prevent this behavior by passing data to this method.</p>
<p>This also means, that you can use data from a textarea or a report for the APEX plugin, to overwrite the existing data and you do not need to configure any query to run this plugin. If you do so and you do not pass data to the <code>start</code> method on the very first call, then the plugin provides sample data - it is the same data with the <a href="https://apex.oracle.com/pls/apex/f?p=18290:1">APEX online demo</a> of this plugin, there is no query configured and you get therefore the sampledata :-)</p>

<div class="description">
<p>The graph is centered to the given position and scaled to the calculated scale factor (effective graph with / viewportWidth).</p>
<p>The reason to have a viewportWidth instead of a scale factor is, that you can rely on given data like the coordinates and radius of a node without calculating the scale factor by yourself - you define your desired viewport width and the zoom method is calculating the neccesary scale factor for this viewport width. If the calculated scale factor is less or greater then the configured minimum and maximum scale factors, then these configured scale factors are used. The reason for this a good user experience, since the graph would be otherwise falling back on these scale factors when the user is scaling the graph by mouse or touch events. </p>

<p>If true, you can zoom and pan the graph.</p>
<p>ATTENTION: When zoomMode is set to true then the lassoMode is only working with the pressed alt or shift key.</p>
<p>KNOWN BUG: In iOS it is after the first zoom event no more possible to drag a node - instead the whole graph is moved - this is, because iOS Safari provide a wrong event.target.tagName. Also a problem: your are not able to press the alt or shift key - if you want to use lasso and zoom together on a touch device, you have to provide a workaround. One possible way is to provide a button, which turns zoom mode on and off with the API zoomMode method - then the user has the choice between these two modes - not comfortable, but working.</p>

<p>Automatically zoom at resize (API call of <code>width</code>, <code>height</code> or responsive change of parent container size with option <code>useDomParentWidth</code> set to true), so that the whole graph is visible and optimal sized. </p>
<p>The event is harmonized/delayed for performance reasons. It could fire very often when for example the browser window is resized by the user. If the graph force simulation is running and not cooled down it is executed on the force end event. Also see the corresponding option <code>onResizeFunctionTimeout</code> which has a default value of 300 (milliseconds).</p>
<p>If you only want to resize your graph once than have a look at the command/helper method <code>zoomToFit</code>:</p>
<pre class="prettyprint source"><code>//change config and resize once
example.zoomToFitOnResize(true).zoomToFit();
//resize only once
example.zoomToFit();</code></pre>
