While we attempt to keep this list up-to-date, a more complete list can be found in the <code>Dygraph.DEFAULT_ATTRS</code> map in <code>dygraph.js</code> and the <code>this.options</code> map in <code>dygraph-canvas.js</code>.</p>

+ <h2 id="gwt">GWT Compatibility</h2>
+ <p>There is currently no GWT wrapper around Dygraphs, however there is a class that can be used to easily load Dygraphs into the browser. To use it, include the generated dygraph-gwt.jar file in your classpath and add the following line to your GWT module:</p>
+
+<pre>
+<inherits name="org.danvk.dygraphs"/>
+</pre>
+
+ <p>Call org.danvk.Dygraphs.install() when your application starts to install the JavaScript code into the browser. You can use <a href="http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html">JSNI</a> to call Dygraphs from your GWT code, as in the example below. The example uses the <a href="http://code.google.com/p/gwt-google-apis/wiki/VisualizationGettingStarted">Visualization API for GWT</a> and the <a href="#gviz">Dygraphs GViz API.</a></p>
+
+<pre>
+ public static native JavaScriptObject drawDygraph(Element element, DataTable data, double minY, double maxY) /*-{
+ var chart = new $wnd.Dygraph.GVizChart(element);
+ chart.draw(dataTable,
+ {
+ valueRange: [minY, maxY]
+ });
+ return chart;
+ }-*/;
+</pre>
+
<h2 id="policy">Data Policy</h2>
<p>dygraphs is purely client-side JavaScript. It does not send your data to any servers – the data is processed entirely in the client's browser.</p>
