title: Insert Checkbox in Dygraph
body: <p><a href="http://dygraphs.com/tests/visibility.html" rel="nofollow">http://dygraphs.com/tests/visibility.html</a> </p>
  
  <p>Anybody know the code to create a checkbox for dygraphs?</p>
  
  <p>Here is an example code:</p>
  
  <pre><code> Date     A      B  
   8/1      5      6
   8/2      6      9
   8/3      2      4
  </code></pre>
  
  <p>I want to create a checkbox that will give you the option to choose A,B, or both. </p>
  
  <p>Thanks!</p>
