title: Pandas Timeseries plotting
body: <p>I have a Pandas timeseries object with dates and corresponding values. But, when I try to plot it, the plot is a L-shape plot (the dates and values are automatically arranged in such a way that the highest value comes first...).</p>
  
  <p>This is what  did to generate the plot:</p>
  
  <pre><code>df = pd.read_csv('C:\data\test1.csv') # two-column dataframe
  data_list = df['values'].tolist()
  dates_list = df['date'].tolist()
  df_ts = pd.Series(data_list, index=dates_list)
  df_ts.plot()
  </code></pre>
  
  <p>I am not sure where I am making a mistake. I am reading in a csv file, converting to a timeseries obj and plotting it. Any suggestions is very much appreciated.</p>
  
  <p>Thanks!
  PD</p>
