title: Can anyone explain me seaborn's set_context()?
body: <p>I am trying to learn visualization with python and stuck here:</p>
  
  <pre><code>sns.set_context('notebook')
  
  ax = data.plot.hist(bins=25, alpha=0.42)
  ax.set_xlabel('Size (cm)');
  </code></pre>
  
  <p>Can anyone help me to explain what does this code sample mean?</p>
