title: Pandas: plot multiple time series DataFrame into a single plot
body: <p>I have the following pandas DataFrame:</p>
  
  <pre><code>     time      Group      blocks
  0     1        A           4
  1     2        A           7
  2     3        A           12
  3     4        A           17
  4     5        A           21 
  5     6        A           26
  6     7        A           33
  7     8        A           39
  8     9        A           48
  9     10       A           59
      ....        ....          ....
  36     35      A           231
  37     1       B           1
  38     2       B           1.5
  39     3       B           3
  40     4       B           5
  41     5       B           6
      ....        ....          ....
  911    35      Z           349
  </code></pre>
  
  <p>This is a dataframe with multiple time series-ques data, from <code>min=1</code> to <code>max=35</code>. Each <code>Group</code> has a time series like this. </p>
  
  <p>I would like to plot each individual time series A through Z against an x-axis of 1 to 35. The y-axis would be the <code>blocks</code> at each time. </p>
  
  <p>I was thinking of using something like an <a href="http://pandas.pydata.org/pandas-docs/stable/visualization.html" rel="noreferrer">Andrews Curves plot</a>, which would plot each series against one another. Each "hue" would be set to a different group. (Other ideas are welcome.)</p>

  <p>My problem: how do you format this dataframe to plot multiple series? Should the columns be <code>GroupA</code>, <code>GroupB</code>, etc.? </p>
  
  <p>How do you get the dataframe to be in the format:</p>
  
  <pre><code>time GroupA blocksA GroupsB blocksB GroupsC blocksC....
  </code></pre>
  
  <p>Is this the correct format for an Andrews plot as shown? </p>
  
  <p>EDIT</p>
  
  <p>If I try:</p>
  
  <pre><code>df.groupby('Group').plot(legend=False)
  </code></pre>
  
  <p>the x-axis is completely incorrect. All time series should be plotted from 0 to 35, all in one series. </p>

  <p>How do I solve this? </p>
