ValueError: The number of FixedLocator locations (7), usually from a call to set_ticks, does not match the number of ticklabels (13)

Question

This code was working before, but now it's not working.

market_segment_confirmed_df = pd.DataFrame(hotel_confirmed_df.groupby(['hotel','market_segment']).agg({'is_canceled':'count'})).reset_index().rename(columns = {'is_canceled':'confirmed_bookings'})


plt.figure(figsize = (8,4))
mpl.rcParams['font.size'] = 11
sns.barplot(x = 'market_segment', y= 'confirmed_bookings', hue = 'hotel', data=market_segment_confirmed_df).set_xticklabels(market_segment_confirmed_df['market_segment'], rotation=30)
plt.title('Market segment wise confirmed bookings.')
plt.grid()

It's throwing the following error:

ValueError                                Traceback (most recent call last)

ValueError: The number of FixedLocator locations (7), usually from a call to set_ticks, does not match the number of ticklabels (13).

Not able to figure out what the problem is. Can anyone help me out?
