title: Seaborn plot does not show all column values
body: <p>I have the following dataframe:</p>
  
  <pre><code>my_df = pd.DataFrame(data={'Year': ['2017','2018','2019','2019','2019','2019','2020','2020'],
        'Threshold':[96, 91, 20.59, 47.37, 78.12, 10.00, 15.00 ,91],
        'Fee' : ["No","No", "20%", "20%", "5%", "20%", "20%", "No"]})
  </code></pre>
  
  <p>I am using seaborn to plot it:</p>
  
  <pre><code>palette={"No": "g","20%": "y", "5%": "r"}
  
  fig,ax = plt.subplots()
  fig.set_size_inches(10,8)
  
  sns.barplot(x="Year", y="Threshold",hue = 'Fee', palette = palette, data=my_df, ci=None)
  
  for p in ax.patches: 
      ax.annotate("%.2f" % p.get_height(), (p.get_x() + p.get_width() / 2, p.get_height()),
                  ha='center', va='center', fontsize=11, color='black', xytext=(0, 10), 
                  textcoords='offset points',fontweight='bold')
  </code></pre>
  
  <p>However, the displayed graph returns the average of the Threshold variable per Year and I want to show all 8 dataframe Thresholds on the graph.</p>

  <p>How can I fix it? </p>
