Seaborn boxplot box assign custom edge colors from Python list
<p>I am trying to change the appearance of boxes in Seaborn's boxplot. I would like all boxes to be transparent and for the box borders to be specified from a list. Here is the code I am working with:</p>

<pre><code>import numpy as np
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
fig, ax = plt.subplots()

df = pd.DataFrame(np.random.rand(10,4),columns=list('ABCD'))
df['E'] = [1,2,3,1,1,4,3,2,3,1]

sns.boxplot(x=df['E'],y=df['C'])

# Plotting the legend outside the plot (above)
box = ax.get_position()
ax.set_position([box.x0, box.y0 + box.height * 0.1, box.width, box.height * 0.9])
handles, labels = ax.get_legend_handles_labels()
leg = plt.legend(handles[0:2], labels[0:2],
                               loc='upper center', bbox_to_anchor=(0.5, 1.10), ncol=2)
plt.show()
</code></pre>

<p>This <a href="https://stackoverflow.com/questions/36305695/assign-a-color-to-a-specific-box-in-seaborn-boxplot">post</a> shows how to change the color and box edgecolor of one single box. However, I would like to assign box edgecolors based on a list like this <code>box_line_col = ['r','g',b','purple']</code>. The above code produces 4 boxes in the plot - I would like to assign custom box edge colors starting from the first (leftmost) box and continuing through to the last (rightmost) box.</p>

<p>Is it possible to to specify the box edge colors from a list, while keeping the boxes themselves transparent (facecolor = white)?</p>
