These are the options that can be passed in through the optional third parameter of the Dygraph constructor. Under each option is a set of links to tests which demonstrate its use.
+These are the options that can be passed in through the optional third parameter of the Dygraph constructor. Under each option is a set of links to tests which demonstrate its use. While we attempt to keep this list up-to-date, a more complete list can be found in the Dygraph.DEFAULT_ATTRS map in dygraph.js and the this.options map in dygraph-canvas.js.

When set, this callback gets called every time the dygraph is drawn. This includes the initial draw, after zooming and repeatedly while panning. The first parameter is the dygraph being drawn. The second is a boolean value indicating whether this is the initial draw.

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:
+ ++<inherits name="org.danvk.dygraphs"/> ++ +
Call org.danvk.Dygraphs.install() when your application starts to install the JavaScript code into the browser. You can use JSNI to call Dygraphs from your GWT code, as in the example below. The example uses the Visualization API for GWT and the Dygraphs GViz API.
+ +
+ public static native JavaScriptObject drawDygraph(Element element, DataTable dataTable, double minY, double maxY) /*-{
+ var chart = new $wnd.Dygraph.GVizChart(element);
+ chart.draw(dataTable,
+ {
+ valueRange: [minY, maxY]
+ });
+ return chart;
+ }-*/;
+
+
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.
