title: Plot side by side box and whisker plots from two dataframes
body: <p>I'm hoping to take these two box plots and combine them into one image:
  [![These are two data files I was able to make box and whisker charts for easily using Seaborn boxplot][1]][1]</p>
  <p>The datafile I am using is from multiple excel spread sheets and looks like this:</p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>0</th>
  <th>1</th>
  <th>2</th>
  <th>3</th>
  <th>4</th>
  <th>5</th>
  <th>6</th>
  <th>...</th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>5</td>
  <td>2</td>
  <td>3</td>
  <td>5</td>
  <td>6</td>
  <td>2</td>
  <td>5</td>
  <td>...</td>
  </tr>
  <tr>
  <td>2</td>
  <td>3</td>
  <td>4</td>
  <td>6</td>
  <td>1</td>
  <td>2</td>
  <td>1</td>
  <td>...</td>
  </tr>
  <tr>
  <td>1</td>
  <td>2</td>
  <td>4</td>
  <td>6</td>
  <td>7</td>
  <td>8</td>
  <td>9</td>
  <td>...</td>
  </tr>
  <tr>
  <td>...</td>
  <td>...</td>
  <td>...</td>
  <td>...</td>
  <td>...</td>
  <td>...</td>
  <td>...</td>
  <td>...</td>
  </tr>
  </tbody>
  </table>
  </div>
  <p>Where the column headers represent hours and the column values are the ones I want to use to create box and whisker plots with.</p>
  <p>Currently my code is this:</p>
  <pre><code>import seaborn as sns
  import pandas as pd
  import matplotlib.pyplot as plt
  
  xls = pd.ExcelFile('ControlDayVar.xlsx')
  df1= pd.read_excel(xls, 'DE_ControlDays').assign(Location=1)
  df2= pd.read_excel(xls, 'DE_FestDays').assign(Location=2)
  DE_all =pd.concat([df1,df2])
  DE= pd.melt(DE_all, id_vars=['Location'], var_name=['Hours'], value_name='Concentration')
  ax= sns.boxplot(x='Hours', y= 'Concentration', hue= 'Location', data=DE)
  plt.show()
  
  The result I get is this:

  I expect my issue has to do with the format of my data files, but any help would be appreciated.Thanks!
