title: Separating seaborn barplot with two colors
body: <p>I have the following dataset:</p>
  
  <pre><code>words = ['upvoted', 'upvote', 'f***', 'reimer', 'feminists', 'censorship',
         'wet', '0001f914', 'turtle', '0001f602', 'vegans', 'thumbnail',
         'lobby', 'mods', 'removed', 'bitches', 'saffron', 'broadband',
         'hitler', 'ass', 'deleted', 'u', 'tits', 'cheating', 'antifa',
         'iâ', 'â', 'itâ', 'donâ', 'edit', 'thatâ', 'isnâ', 'doesnâ',
         'didnâ', 'canâ', 'youâ', 'theyâ', 'eli5', 'weâ', 'arenâ', 'thereâ',
         'hi', 'wouldnâ', '½ï', 'whatâ', 'ï', '½', 'wasnâ', 'wonâ',
         'eclipse'] 
  
  coefs = [ 1.00157191,  0.95931338,  0.92066619,  0.86347946,  0.83977936,
          0.83912351,  0.83482245,  0.8148754 ,  0.79982483,  0.79402501,
          0.7687297 ,  0.76765479,  0.76096785,  0.75893433,  0.75177131,
          0.74486391,  0.73244163,  0.71302245,  0.70449932,  0.70346844,
          0.69737316,  0.67902944,  0.6746799 ,  0.67338842,  0.6678747 ,
         -2.83723585, -2.82874502, -2.59032368, -2.52985115, -2.1811188 ,
         -1.87094025, -1.66191757, -1.64283967, -1.62282287, -1.61855926,
         -1.55062817, -1.54397537, -1.39775882, -1.3492324 , -1.30638486,
         -1.29859752, -1.14761071, -1.0673105 , -1.06272808, -1.02998239,
         -0.96635257, -0.94262438, -0.91244845, -0.90765028, -0.87274524]
  </code></pre>
  
  <p>and I would like to make a barplot with two colors, one for negative and one for positive values of the coefficient. </p>
  
  <p>My efforts have lead me to: </p>
  
  <pre><code>sns.set(rc={'figure.figsize':(20,10)})
  sns.set(font_scale = 1.5)
  g = sns.barplot(words,coefs, palette =sns.diverging_palette(220, 20, n=50, center = "dark"))
  plt.xticks(rotation=90)
  plt.show()
  </code></pre>
  
  <p>But even here I cannot trully separate them, it only makes a scale of colors.</p>
