title: Show value within bar on flot bar chart
body: <p>I would like to show the value within the bar on the <a href="http://code.google.com/p/flot/" rel="noreferrer">flot</a> bar chart, something like this:</p>
  
  <pre><code>|
  |               +----+
  |               |    |
  |               |    |
  |               |    |
  |   +----+      | 20 |
  |   |    |      |    |
  |   | 10 |      |    |
  |   |    |      |    |
  |---+----+------+----+------
  </code></pre>
  
  <p>data = [[1, 10], [2, 20]]</p>
  
  <p>Is there a way to do this?</p>
