title: FutureWarning: Pass the following variables as keyword args: x, y
body: <p>I want to plot a seaborn regplot.
  my code:</p>
  <pre><code>x=data['Healthy life expectancy']
  y=data['max_dead']
  sns.regplot(x,y)
  plt.show()
  </code></pre>
  <p>However this gives me future warning error. How to fix this warning?</p>
  <pre><code>FutureWarning: Pass the following variables as keyword args: x, y. From version 0.12, the only valid 
  positional argument will be 'data', and passing other arguments without an explicit keyword will 
  result in an error or misinterpretation.
