title: How to change axes linewidth in 3D matplotlib?
body: <p>I am trying to change the line width of the axes in <code>3D</code> plots in <code>matplotlib</code>. I have tried:</p>
  
  <pre><code>"mpl.rcParams['axes.linewidth'] = 8"
  
  and
  
  "pl.rc("axes", linewidth=8.0)"
  </code></pre>
  
  <p>but none of them worked. I would be grateful for any suggestions.</p>
