title: Seaborn: barplot the counting not mean value of a column
body: <p>I am the beginner with seaborn plot. as the sample, seaborn provides a bar graph with the average "days". However, is it possible to provide a bar graph with total(sum), counting,..of the days values?</p>
  
  <pre><code>import seaborn as sns 
  sns.set_style("whitegrid")
  tips = sns.load_dataset("tips")
  ax = sns.barplot(x = "day",y = "total_bill",data=tips)
  </code></pre>
