title: Python line plot multiple time series on same plot
body: <p>I'm parsing a file that has chronologically timestamped data for multiple time series that I would like to parse in python and then use matplotlib to create a single line plot with independent lines for each set of time series data. The data I'm parsing looks something like this:</p>
  
  <pre><code>time label   value
  1.05 seriesA 3.925
  1.09 seriesC 0.245
  2.13 seriesB 12.32
  2.73 seriesC 4.921
  </code></pre>
  
  <p>I've parsed the file into a dictionary of lists that contain (time,value) tuples keyed on the series label. I'm struggling with how to get from this to a single line plot with all this data. I want independent lines for seriesA, seriesB, seriesC, etc. on a single plot. Any pointers?</p>
  
  <p>Edit: As requested the dictionary is below. I had a hard time figuring out the best way to store this data so maybe the data structure I'm using is also a problem. The keys below are the different time series labels and the values are a list of (time,value) tuples. In any case, here it is:</p>

  (862.281483262, 0.0), (862.289038158, 153600000.0)], 'client3':
