title: how to plot list of tuples, generated by groupby
body: <p>I want to plot each list of tuples generated by groupby command.</p>
  
  <pre><code>import more_itertools as mit
  df=pd.DataFrame({'a': [0,1,2,0,1,2,3], 'b':[2,10,24,56,90,1,3]})
  for group in mit.consecutive_groups(zip(df['a'],df['b']),ordering=lambda t:t[0]):
       print(list(group))
  </code></pre>
  
  <p>output:
      <code>[(0, 2), (1, 10),(2,24)] 
         [(0,56),(1,90),(2,1),(3,3)]</code></p>
  
  <p>I want to plot first index of group <code>[(0, 2), (1, 10),(2,24)]</code> taking first element as x and second element of tuple as y ( x=0,y=2). The same applies to following list of tuples. I am still trying, but have not figured yet.  </p>
