title: How can I hide the axes in matplotlib 3d?
body: <p>How can I make a 3D plot without showing the axes?</p>
  
  <p>When plotting a 3d plot, Matplotlib not only draws the x, y, and z axes, it draws light gray grids on the x-y, y-z, and x-z planes. I would like to draw a "free-floating" 3D plot, with none of these elements.</p>
  
  <p>Stuff I've tried:</p>
  
  <pre><code># Doesn't work; this hides the plot, not the axes
  my_3d_axes.set_visible(False)
  
  # Doesn't do anything. Also, there's no get_zaxis() function.
  my_3d_axes.get_xaxis().set_visible(False)
  my_3d_axes.get_yaxis().set_visible(False)
  </code></pre>
