how to order the bars in the order as they receive in matplotlib in python?

Question

How to order the bars in the frequency plot in the order of 0,1,2,3,4 instead of the highest frequency as shown in the below picture?

This is the code i used:

train_df.Fedu.value_counts().plot(kind='bar', alpha=0.6)
plt.title("Distribution of Father's  education")

Answer 1

Use sort_index:

train_df.Fedu.value_counts().sort_index().plot(kind='bar')
