title: Pandas DataFrame step plot: where="post"
body: <p>I am wondering how I can pass matplotlibs <a href="http://matplotlib.org/examples/pylab_examples/step_demo.html" rel="noreferrer">where="post"</a> into a pandas plot.</p>
  
  <pre><code>import numpy as np
  import pandas as pd
  
  df = pd.DataFrame(np.random.randn(36, 3))
  df.plot(drawstyle="steps", linewidth=2)
  
  # this doesn't work
  df.plot(drawstyle="steps", where='post')
  </code></pre>
  
  <p>Does anyone know how to realize this?</p>
  
  <p>Thanks in advance!</p>
