title: Plotting with Numpy Arrays
body: <p>Sorry for the introductory nature of this post. I am relatively new to Python and was trying to learn to visualize data. I am currently trying to plot plot a time series of the relative frequencies of certain terms over time. An abridged version of the data I am using is listed below:</p>
  
  <pre><code>abridged_data = {'wandered': [[2005, 5.807135648994622e-06], [2006, 5.7273128507756315e-06], [2007, 6.7032709205293806e-06], [2008, 8.777680961941695e-06]], 'airport': [[2007, 1.0841708003745173e-05], [2008, 8.89465511574262e-06]], 'request': [[2005, 4.479519997292191e-05], [2006, 4.427159014360846e-05], [2007, 4.3048248627066294e-05], [2008, 4.081853901820637e-05]]}
  </code></pre>
  
  <p>I currently have code using the matplotlib.pyplot module that allows me access this data and to plot the frequency of one term over time, which I have pasted below.</p>
  
  <pre><code>x = np.array(mydata['wandered'])[:,0]
  y = np.array(mydata['wandered'])[:,1]
  plt.plot(x, y)
  plt.show()
  </code></pre>
  
  <p>However, I haven't been able to take the data stored in the <code>abridged_data</code> dictionary and use it to plot more than one line on my graph. I was hoping someone might be able to show me the best way to access my existing dictionary to plot the data for all of the terms.</p>
  
  <p>Thanks in advance for your help. I really appreciate it. </p>
