title: How to sort a FacetGrid legend?
body: <p>In the image below, how do I sort the legend to show 'No' above 'Yes'? Thanks</p>
  <pre><code>import pandas as pd
  import seaborn as sb
  from matplotlib import pyplot as plt
  
  df = sb.load_dataset('tips')
  g = sb.FacetGrid(df, col='sex', hue='smoker', col_wrap=2)
  g.map(plt.scatter, 'total_bill', 'tip', alpha=.7)
  g.axes[-1].legend() 
  plt.show()
  </code></pre>
