I am trying to add some space between bars. Here is an example of the bar chart that I want to modify,

import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd

df = pd.DataFrame({'Name': ['Alex', 'Alex', 'Sofia', 'Sofia'], 'Age': [15, 18, 16, 22], 'Gender': ['M', 'F', 'M', 'F']})

age_plot = sns.barplot(data=df, x="Age", y="Name", hue="Gender")
plt.show()

I want to add some space between the M and F bars. Right now they are completely attached. I have searched and searched but haven't found a good solution. There was one solution that suggested to add an empty category but that does not work for my dataset.

Using edgecolor and linewidth

One way to do this is via using linewidth and edgecolor parameters -

import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd

df = pd.DataFrame({'Name': ['Alex', 'Alex', 'Sofia', 'Sofia'], 
                   'Age': [15, 18, 16, 22], 
                   'Gender': ['M', 'F', 'M', 'F']})

age_plot = sns.barplot(data=df, x="Age", y="Name", hue="Gender", linewidth=5, edgecolor='w')
plt.show()

Using set_width

Another way would be to use set_width over each of the patches in the plot.

import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd

df = pd.DataFrame({'Name': ['Alex', 'Alex', 'Sofia', 'Sofia'], 
                   'Age': [15, 18, 16, 22], 
                   'Gender': ['M', 'F', 'M', 'F']})

age_plot = sns.barplot(data=df, x="Age", y="Name", hue="Gender")

for i in age_plot.patches:
  i.set_height(0.3)

plt.show()
