Seaborn: how to set bar borders' line width or color?

Question

I am trying to draw a barplot with bars with no borders. By default bars has thin black borders. In the devlopment version (0.6) of Seaborn, I could pass kwargs (linewidth, edgecolor) to pyplot.bar() via seaborn.barplot(), but in the current version (0.5.1) this feature seems not yet available. Looking at the returned AxesSubplot object, I could not find the way to set the line width to zero, or the color to fully transparent, although it has many methods, so I still hope there is a way to achieve this.

import matplotlib.pyplot as plt
import seaborn as sns

fig, ax = plt.subplots()
ax = sns.barplot(data = data, x = 'var1', color = '#007b7f')
fig.tight_layout()
fig.savefig('fig.pdf')

Answer 1

This will work too:

fig, ax = plt.subplots()
ax = sns.barplot(data = data, x = 'var1', color = '#007b7f')
plt.setp(ax.patches, linewidth=0)

Answer 2

After many attempts without success, I asked the question here, and soon I found the solution myself. So here it is: before plotting, the patch.linewidth parameter can be set with seaborn.set_context():

import seaborn as sns

sns.set_context(rc = {'patch.linewidth': 0.0})
ax = sns.barplot(...)
