title: Vertical Line in barplot
body: <p>I have a dataframe named IAT like this:</p>
  
  <pre><code>dados = [["2019-10",20.59,"Glosa de 5%"],["2019-10",47.37,"Glosa de 5%"],["2019-10",78.12,"Glosa de 5%"],["2019-10",10,"Glosa de 5%"],["2019-11",15,"Glosa de 5%"],["2019-10",96,"Nenhuma Penalidade"],["2019-10",91,"Advertência"], ["2019-10",91,"Advertência"]] 
  
  IAT = pd.DataFrame(dados, columns=['Conclusao Real', 'Indicador de Prazo', 'Penalidade'])
  </code></pre>
  
  <p>I want to plot "Conclusao Real" x "Indicador de Prazo" using the column "Penalidade" as the color bars.</p>
  
  <p>My plot got right, but there is a black vertical line inside the third bar that I did not understand the reason it appeared:</p>
  
  <p><a href="https://i.stack.imgur.com/O5WS5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/O5WS5.png" alt="Plot"></a></p>
  
  <p>My plot code:</p>
  
  <pre><code>import seaborn as sns
  
  IAT.sort_values('Conclusao Real',inplace=True,ascending=True)
  
  fig,ax = plt.subplots()
  fig.set_size_inches(10,6)
  
  g=sns.barplot(x='Conclusao Real',y='Indicador de Prazo',data=IAT, hue='Penalidade',ax=ax)
  </code></pre>
  
  <p>What is wrong with this code above?</p>
  
  <p>Is there another better way to plot it?</p>
