title: How to plot two legend with distplot
body: <p>I want to plot two labels in my graph, but I didn't succeed to do that. It displays only the last label <code>"Old_Formula"</code>.</p>
  
  <p>Here is a simple example</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import numpy as np
  import seaborn as sns
  
  values1 = np.array([1, 2, 2, 5, 3, 4, 7, 4, 3, 3])
  values2 = np.array([1, 4, 4, 6, 3, 1, 7, 1, 7, 6])
  f, (ax1, ax2) = plt.subplots(1, 2, sharex=True)
  sns.distplot(values1, ax=ax1, kde=False, label="New_Formula")
  sns.distplot(values2, ax=ax2, kde=False, label="Old_Formula")
  plt.legend()
  plt.show()
  </code></pre>
