title: Labels disappear from jQuery Flot when scrolling right (with tick rotor)
body: <p>When I load the page, everything is ok. Nevertheless, when I scroll right (to show the next days), the ticks disappear. I use the tickrotor.js to rotate the ticks.</p>
  
  <pre><code>xaxis: {
                  panRange: [0, null],
                  mode: "categories",
                  tickLength: 1,
                  rotateTicks: 135,
                  min: 0,
                  max: 15,
                  labelWidth: 30},
  </code></pre>
  
  <p>Any ideas to solve this?</p>
