title: Changing pointplot legend in seaborn
body: <p>I would like to change the label for the legend and items in the legend for this plot. Right now the label for the legend is "Heart" and the items are 0 and 1. I would like to be able to change all of these to something else, but am unsure how. Here is what I have so far. </p>
  
  <pre><code>sns.set_context("talk",font_scale=3)
  ax =sns.pointplot(x="Heart", y="FirstPersonPronouns", hue="Speech", data=df)
  ax.set(xlabel='Condition', ylabel='First Person Pronouns')
  ax.set(xticklabels=["Control", "Heart"])
  </code></pre>
  
  <p>Any help would be appreciated! Also, I'm assuming this is a set parameter that I don't know about, is there a comprehensive list of these? I can't seem to find one in the documentation. </p>
