title: Histogram Matplotlib
body: <p>So I have a little problem. I have a data set in scipy that is already in the histogram format, so I have the center of the bins and the number of events per bin. How can I now plot is as a histogram. I tried just doing </p>
  
  <pre><code>bins, n=hist()
  </code></pre>
  
  <p>but it didn't like that. Any recommendations?</p>
