Add data labels to Seaborn factor plot

Question

I would like to add data labels to factor plots generated by Seaborn. Here is an example:

import pandas as pd
from pandas import Series, DataFrame
import nu         


        

Answer 1

The above answer from @nickil-maveli is simply great. This is just to add some clarity about the parameters when you are adding the data labels to the barplot (as requested in the comments by @user27074)

 # loop through all bars of the barplot
for nr, p in enumerate(ax.patches):

    # height of bar, which is basically the data value
    height = p.get_height() 

    # add text to specified position
    ax.text(
        # bar to which data label will be added 
        # so this is the x-coordinate of the data label
        nr, 

        # height of data label: height / 2. is in the middle of the bar
        # so this is the y-coordinate of the data label
        height / 2., 

        # formatting of data label
        u'{:0.1f}%'.format(height), 

        # color of data label
        color='black', 

        # size of data label
        fontsize=18, 

        # horizontal alignment: possible values are center, right, left
        ha='center', 

        # vertical alignment: possible values are top, bottom, center, baseline
        va='center'
    )
