title: How to change the theme of a Highstock graph with a button?
body: <p>So I import a few different themes like this:</p>
  
  <pre><code>&lt;script src="/js/themes/skies.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/sand-signika.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/grid.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/grid-light.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/gray.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/dark-unica.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/dark-green.js"&gt;&lt;/script&gt;
  &lt;script src="/js/themes/dark-blue.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>And I activate them like this:</p>
  
  <pre><code>Highcharts.setOptions(Highcharts.skies);
  </code></pre>
  
  <p>Putting this above the graph works just fine, but when I try to use buttons so that I can change them on my website, nothing happens. What I've tried is this:</p>
  
  <pre><code>$('#skies').click(function () {
      Highcharts.setOptions(Highcharts.skies);
  });
  </code></pre>
  
  <p>I know that the button works, as I've tested it with window.alert(), but why doesn't the theme get updated? </p>
