title: Plot smoothing matplotlib and seaborn
body: <p>I am trying to display my data in a nice way such as seen on the seaborn documentation:</p>
  
  <p><img src="https://seaborn.pydata.org/_images/errorband_lineplots.png" alt="Text"></p>
  
  <p>I am not too sure how to proceed. I managed to get the values of points and their respective standard deviation but it looks scattered while I just want to show a tendency:</p>

  <p>I look into <a href="https://stackoverflow.com/questions/5283649/plot-smooth-line-with-pyplot">here</a>, and <a href="https://stackoverflow.com/questions/25825946/generating-smooth-line-graph-using-matplotlib/25826265">there</a> trying to apply the proposed solution but I couldn't make it work.</p>
  
  <p>Here is what I play with:</p>
  
  <pre><code>Final_array =         Mean       Std
  0   0.739269  0.157892
  1   0.807382  0.160464
  2   0.800024  0.137239
  3   0.825854  0.132472
  4   0.864854  0.070544
  ..       ...       ...
  95  0.797202  0.101961
  96  0.747578  0.143394
  97  0.751472  0.158651
  98  0.587009  0.198987
  99  0.728447  0.104601
  
  sns.set(style="darkgrid", palette="muted", color_codes=True)
  fig, ax = plt.subplots(figsize=(7,5))
  y_pos = np.arange(Final_array.shape[0])
  ax.errorbar(y_pos, Final_array[:,0], yerr=Final_array[:,1], elinewidth=0.5)
  plt.show()
  </code></pre>
  
  <p>Does anyone have an idea? I am very beginner in using plots. Would it be possible to smooth? and get the nice overlay as in the seaborn image instead of the error bars?</p>
  
  <p>These might be silly questions.</p>
  
  <p>Kind regards,</p>
