title: matplotlib does not show plot()
body: <p>I tried running plt.show() but no plot is shown. I had tried lots of solutions from stackoverflow including setting matplotlib backend to Qt4Agg, switching to other backends (i.e. TkAgg, Agg) and reinstalling matplotlib package but still not solving the issue. Some solutions that I had tried but not working are: </p>

  <p>Below is the code that I tried to run:</p>
  
  <pre><code>plt.scatter(pf["age"], pf["friend_count"])
  plt.xlabel = "age"
  plt.ylabel = "friends count"
  plt.title = "Facebook Friends count by Age"
  plt.show()
  </code></pre>
  
  <p>When <code>plt.scatter(pf["age"], pf["friend_count"])</code> code was run, a scatter plot was shown but with no labels and title. Running <code>plt.show()</code> did not plot and no error was shown. Appreciate any help.</p>
