title: Python Seaborn Chart - Shadow Area
body: <p>Sorry to my noob question, but how can I add a shadow area/color between the upper and lower lines in a seaborn chart?</p>
  <p>The primary code I've working on is the following:</p>
  <pre><code>plt.figure(figsize=(18,10))
  sns.set(style=&quot;darkgrid&quot;)
  palette = sns.color_palette(&quot;mako_r&quot;, 3)
  sns.lineplot(x=&quot;Date&quot;, y=&quot;Value&quot;,  hue='Std_Type', style='Value_Type', sizes=(.25, 2.5), palette = palette, data=tbl4)
  </code></pre>

  <p>The idea is to get some effect like below (the example from seaborn website):
  But I could not replicate the effect although my data structure is pretty much in the same fashion as <strong>fmri</strong> (seaborn example)</p>
  <p><em>from seaborn</em> <a href="https://seaborn.pydata.org/examples/errorband_lineplots.html" rel="nofollow noreferrer">link</a>:</p>
  <pre><code> import seaborn as sns
   sns.set(style=&quot;darkgrid&quot;)
  
   # Load an example dataset with long-form data
   fmri = sns.load_dataset(&quot;fmri&quot;)
  
   # Plot the responses for different events and regions
   sns.lineplot(x=&quot;timepoint&quot;, y=&quot;signal&quot;,
           hue=&quot;region&quot;, style=&quot;event&quot;,
           data=fmri)
  </code></pre>

  <p>Do you have some ideas?
  I tried to change the chart style, but if I go to a <code>distplot</code> or <code>relplot</code>, for example, the <code>x_axis</code> cannot show the timeframe...</p>
