title: cannot change seaborn regplot regression line size?
body: <p>The usual <code>width=10</code> does not work for the regplot I can change the scatter size if it was turned on however its just the regression line size/width that I am attempting to change.</p>
  <p>I have checked the documentation and cannot find any parameters which will do this. I am sure its a simple fix just cannot seemed to find it ?</p>
  <p>Other parameters I have attempted are as follows</p>
  <pre><code>scatter_kws={&quot;linewidth&quot;: 10}
  linewidth=10
  s=10
  sizes=(10, 20)
  </code></pre>
  <p>Admittedly most of my attempts would only work for the scatterplot but just to be clear on what I have dune already.</p>
  <p>Thank you</p>
  <pre><code>import seaborn as sns
  df = pd.DataFrame({&quot;x&quot;: [1, 2, 3, 4, 5, 6], &quot;y&quot;: [10, 30, 60, 90, 60, 30]})
  sns.regplot(x=&quot;x&quot;, y=&quot;y&quot;, data=df, ci=65,scatter=False)
  sns.lineplot(x=&quot;x&quot;, y=&quot;y&quot;, data=df)
  </code></pre>
