title: Why can't I modify the axes from a JavaFX LineChart?
body: <p>I got a <code>LineChart</code> which actually hold two axes. I really need to manipulate the bounds for xAxis and the ticking, however I can't get the axis as a <code>NumberAxis</code>, I just get it as an <code>Axis</code> for which I can't get the setLowerBound method, neither upperBound or tick settings....</p>
  
  <p>How can I solve this?</p>
