title: Removing labels from pie chart moves the legend box
body: <p>I'm trying to do a pie chart where I remove the labels from it. Currently I'm doing this:</p>
  
  <pre><code>qx = queens_tree_types.plot(ax=axes[0], kind='pie', figsize=(8,30), legend=True, 
                              autopct='%1.0f%%', pctdistance=0.9, radius=1.2)
  axes[0].set_title('Queens');
  </code></pre>
  
  <p>Which gives me the following pie:</p>
  
  <p><a href="https://i.stack.imgur.com/AoxiM.png" rel="noreferrer"><img src="https://i.stack.imgur.com/AoxiM.png" alt="enter image description here"></a></p>
  
  <p>That's nice and all, but I want to remove the labels from the chart. When I try and simply do <code>labels=None</code>, I get this picture:</p>
  
  <p><a href="https://i.stack.imgur.com/iwlrp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/iwlrp.png" alt="enter image description here"></a></p>
  
  <p>The initial pie chart has the location of the legends set like this:</p>
  
  <pre><code>qx.legend(bbox_to_anchor=(2.5, 1.05),
        ncol=2, fancybox=True, shadow=True)
  </code></pre>
  
  <p>But when I remove the labels, I can't seem to move the legend box at all. What gives?</p>
