<p>You specify options in the third parameter to the dygraphs constructor:</p>

                  ...
                });
</pre>

<p>After you've created a Dygraph, you can change an option by calling the <code>updateOptions</code> method:</p>
<pre>g.updateOptions({
                  new_option1: value1,
                  new_option2: value2
