title: about rotating axis label in matlab
body: <p>I am plotting some 3-dimensional data with matlab's waterfall, I found that if I set the x- or y-label with the buildin xlabel or ylabel command, the orientation of the label will always be horizontal instead of aligning with the axis. Is that any way to make it oriented along the axis? I found in the help that we can use the command </p>
  
  <pre><code>xlabel('label at 45 degree', 'rot', 45)
  </code></pre>
  
  <p>to specify the angle of orientation but if I rotate the 3D axis manually, the label won't change accordingly, anyway to fix that? Thanks.</p>
