title: positioning flot xaxis labels
body: <p>I am making a plot using flot that has tickmarks at irregular positions,  e.g. one at position 100,  one at position 155,  one at position 230.  Flot is able to put the tickmarks at those locations easily enough.</p>
  
  <p>But I want to put axis labels in between these points,  e.g.</p>
  
  <pre><code>|--------------|-------|------------------|
      blahblah       huh        metoo
  </code></pre>
  
  <p>Can't figure out how to get flot to  this.   Any sugestions?</p>
  
  <p>Thanks</p>
