title: Labels for clustermap in seaborn
body: <p>I have several questions about labeling for <code>clustermap</code> in <code>seaborn</code>. First is it possible to extract the the distance values for the hierarchical clustering, and plot the value on the tree structure visualization (maybe only the first three levels).</p>
  
  <p>Here is my example code for creating a clustermap plot:</p>
  
  <pre><code>import pandas as pd
  import numpy as np
  import seaborn as sns
  get_ipython().magic(u'matplotlib inline')
  
  m = np.random.rand(50, 50)
  df = pd.DataFrame(m, columns=range(4123, 4173), index=range(4123, 4173))
  sns.clustermap(df, metric="correlation")
  </code></pre>

  <p>The other two questions are: 
   - How to rotate the y labels since they overlaps together.<br>
   - How to move the color bar to the bottom or right. (There was a <a href="https://stackoverflow.com/questions/27037241/changing-the-rotation-of-tick-labels-in-seaborn-heatmap">question</a> for heatmap, but does not work for my case. Also does not address the color
     bar position)</p>
