Pandas DataFrame step plot: where="post"
<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>
