title: Plotting multiple subplots, each showing relation between two columns of a pandas DataFrame using Seaborn
body: <p>I have a <em>pandas</em> <a href="https://i.stack.imgur.com/gJ9aH.png" rel="nofollow noreferrer">DataFrame</a> as follows:</p>
  <p><code>df=pd.DataFrame({'depth':[499,500,501,502,503],'parameter1':[25,29,24,23,25],'parameter2':[72,80,65,64,77]})</code></p>
  <p>I wish to plot multiple (two in this case) seaborn <em>lineplots</em> under the same graph, as subplots.
  I want to keep the <em><strong>depth</strong></em> parameter constant on the <em>x-axis</em> but vary the <em>y-axis</em> parameters as per the other column values.</p>
  <p><code>sns.relplot(x='depth',y=&quot;parameter1&quot;,kind='line',data=df)</code></p>
  <p><a href="https://i.stack.imgur.com/4wMt9.png" rel="nofollow noreferrer"><strong>parameter1 vs depth</strong></a></p>
  <p><code>sns.relplot(x='depth',y=&quot;parameter2&quot;,kind='line',data=df)</code></p>
  <p><a href="https://i.stack.imgur.com/lyPCi.png" rel="nofollow noreferrer"><strong>parameter2 vs depth</strong></a></p>
  <p>I have tried to use <code>seaborn.FacetGrid()</code> but I haven't obtained proper results with these.</p>
  <p>Let me know how I can plot these graphs as subplots under a single graph without having to define them individually.</p>
