title: How can I create a time-series bar graph in Ruby on Rails with a hash?
body: <p>I am able to create a time-series "hash" using the statistics gem:</p>
  
  <pre><code>=&gt; #&lt;OrderedHash {"2010-10-23"=&gt;2, "2010-09-22"=&gt;3, "2010-09-11"=&gt;1, "2010-08-27"=&gt;1, "2010-10-15"=&gt;
  1, "2010-09-15"=&gt;1, "2010-08-08"=&gt;2, "2010-10-17"=&gt;14, "2010-10-06"=&gt;2, "2010-09-28"=&gt;1, "2010-10-19
  "=&gt;1, "2010-09-20"=&gt;1}&gt;
  </code></pre>
  
  <p>I want to create a simple graph with this data -- I am trying to use the Seer gem but am confused -- it looks like rather than passing in a series, you pass in a method and it runs it live based on the data.</p>
  
  <p>Is there a way I can take data starting with a hash and display it?</p>
