There is a Pandas dataframe: hotels_rev = df1[['date', 'hotel', 'revenue', 'av_revenue', 'difference', 'in_percent']].sort_values(by=['hotel', 'date']) Construct a sns factorplot plot with x scale = 'date', y scale = 'difference', col = 'hotel'. You should get 6 graphs (one for each 'hotel')

def plot_difference_by_hotel(df):
    sns.factorplot(
        x='date', y='difference', col='hotel',
        data=df, kind='bar')
    
plot_difference_by_hotel(hotels_rev)
