title: Remove legend title from seaborn plot
body: <p>I just wanted to remove the title of a scatterplot made with seaborn. The title is given by the hue parameter. In this case the title is "Pluton"</p>
  
  <p><img src="https://i.stack.imgur.com/A3VMB.png" alt=""></p>
  
  <pre><code>x = sns.scatterplot(x="Al total", y="Fe/Fe+Mg", data=df, hue="Pluton", alpha=1)
  sns.set_style("ticks")
  
  plt.legend(ncol=3, loc='upper center', 
             bbox_to_anchor=[0.5, 1.25], 
             columnspacing=1.3, labelspacing=0.0,
             handletextpad=0.0, handlelength=1.5,
             fancybox=True, shadow=True)
  
  
  plt.ylim(0.2 ,1.1)
  </code></pre>
  
  <p>Thanks!</p>
