- <p>The dygraphs library relies heavily on HTML's <code><canvas></code> tag, which Microsoft Internet Explorer does not support. Fortunately, some clever engineers created the <a href="http://code.google.com/p/explorercanvas/">excanvas</a> library, which implements the <code><canvas></code> tag in IE using VML.</p>
+ <p>The dygraphs library relies heavily on the HTML5 <code><canvas></code> tag, which Microsoft Internet Explorer did not traditionally support. To use Microsoft's native canvas implementation in IE9, you need to set an HTML5 doctype on your page:</p>
+
+<pre>
+<!DOCTYPE html>
+</pre>
+
+ <p>When IE9 is in HTML5 mode, dygraphs works just like in other modern browsers.</p>
- <p>You can add IE support to any page using dygraphs by including the following in your page:</p>
+ <p>If you want to support previous versions of Internet Explorer (IE6–IE8), you'll need to include the <a href="http://code.google.com/p/explorercanvas/">excanvas</a> library, which emulates the <code><canvas></code> tag using VML. You can add excanvas by including the following snippet:</p>
<pre>
-<head>
- <!--[if IE]><script src="excanvas.js"></script><![endif]-->
-</head>
+<!DOCTYPE html>
+<html>
+ <head>
+ <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7; IE=EmulateIE9">
+ <!--[if IE]><script src="path/to/excanvas.js"></script><![endif]-->
+ </head>
</pre>
- <p>This works quite well in practice. Charts are responsive, even under VML emulation.</p>
+<p>(This is surprisingly tricky because the HTML5 doctype breaks excanvas in IE8. See <a href="https://groups.google.com/group/dygraphs-users/browse_thread/thread/c60709e04bc7fe5f#">this discussion</a> for details.)</p>
+
+ <p>While VML emulation sounds like it would be slow, it works well in practice for most charts.</p>
<p>One common gotcha to look out for: make sure you don't have any trailing commas in parameter lists, e.g.</p>
<p>This chart shows monthly closes of the Dow Jones Industrial Average, both in nominal and real (i.e. adjusted for inflation) dollars. The shaded areas show its monthly high and low. CPI values with a base from 1982-84 are used to adjust for inflation.</p>

+ <div id="dow_chart" style="width:750px; height:350px;"></div>
<p><b>Display: </b>
<input type=checkbox id=0 onClick="stockchange(this)" checked>

<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>
