title: Plot Histogram in Python
body: <p>I have two lists, x and y.<br>
  x contains the alphabet A-Z and Y contains the frequency of them in a file.</p>
  
  <p>I've tried researching how to plot these values in a histogram but has had no success with understanding how to plot it.</p>
  
  <pre><code>n, bins, patches = plt.hist(x, 26, normed=1, facecolor='blue', alpha=0.75)
  </code></pre>
  
  <p>Would x be list x in the lists mentioned above?</p>
