title: vizualize categorical and numerical values on the same plot
body: <p>I have the dataframe, the story behind it: score of group student for every month, and the student that contributed the most in the recieving of such a score. What I would like is to plot the score as curve (or bar) and also to visualize the names o(probably as dot for line plot, or just name for every bar) </p>
  
  <pre><code>  Month     Score                _Max
       1         6                 Mike         
       2         5                 Alice
       3         9                 Eleonora
       4         11                 Helen
  </code></pre>
  
  <p>I'm using this method, which is messy, I know, and gives not readable x-ticks labels but I have no other idea how to deal with both categorical and numerical values in time series on the same plot</p>
  
  <pre><code>    df['index_col'] = df.index
      ax=df.plot(kind='bar', color=['red','blue'], figsize=(30,10))
      ax.set_xlabel("Month", fontsize=21)
      ax.set_ylabel("Score", fontsize=21) 
      labels = df._Max[:]
      ax.set_xticklabels(labels, rotation =90)
  </code></pre>
