title: Pulling top 10% of data pandas python
body: <p>I am currently working on a code</p>
  <pre class="lang-py prettyprint-override"><code>VRAM1[VRAM1[&quot;System&quot;] == &quot;AIS V1&quot;].plot(kind='scatter', x='ReportDate', y='Site',figsize = (15,120));
  plt.title('AIS V1 System')
  </code></pre>
  <p>My output is exactly what I want to see.  The frustrating part is how do I see the top 10% of the AIS V1 scatter plot. Currently I see ALL (y='Site'), but I only want to see the top 10% and not all.  The AIS V1 data are objects and not integers so I was not able to use the nlargest() function. Any help would be appreciated.</p>
