title: Excel - Multiple subsets of data on one line graph
body: <p>I'm trying make a line graph that has multiple lines on it, each representing a question number and its data. I cannot get it to display properly. My data is structured like this...</p>
  
  <pre><code>Question Precision      Time
  0        30.49849888    2000
  0        31.44534664    3000
  0        16.87857557    4000
  0        48.49384985    5000
  1        30.49849888    2000
  1        31.44534664    3000
  1        16.87857557    4000
  1        48.49384985    5000
  </code></pre>
  
  <p>The data goes up to 5 questions. How can I create a single line graph in Excel that has separate lines for each question?</p>
  
  <p>I plan to use <code>time</code> on the x axis and <code>precision</code> on the y.</p>
