title: How to remove legend in lmplot function of seaborn?
body: <p>In seaborn lmplot function we have hue argument that will automatically draw a colorbar on the right side. How can I disable/remove the colorbar?</p>
  
  <p>Here are a sample code that will generate a colorbar</p>
  
  <pre class="lang-py prettyprint-override"><code>df = pd.DataFrame({'x':[1,2,3,1,2,3,1,2,3],'y':[1,2,3,2,3,4,3,4,5],'color':['a','a','a','b','b','b','c','c','c']})
  facets = sns.lmplot(data=df, x='x', y='y', hue='color', fit_reg=False)
  facets.fig.show()
  </code></pre>

  <p>I tried to call the colorbar object and remove it. In the traditional matplotlib way we can use</p>
  
  <pre class="lang-py prettyprint-override"><code>collection = ax.scatter(x='a', y='b', data=df)
  colorbar = fig.colorbar(collection)
  </code></pre>
  
  <p>to call it, but I can't see how it works for lmplot. Another alternative way is in sns.heatmap function, where it provides a cbar argument</p>
  
  <pre class="lang-py prettyprint-override"><code>sns.heatmap(crosstab, cbar=False)
  </code></pre>
  
  <p>But in lmplot there is not cbar option. What is the best way to do it in lmplot?</p>
