limit the number of groups shown in seaborn countplot?

Question

Is it possible to show only the top/bottom n groups in asns.countplot()?

Using an example from the seaborn website,

sns.countplot(y="deck", hue="class", data=titanic, palette="Greens_d"); 

Is there any easy (or even relatively straightforward) way of limiting this plot to just 3 decks (groups) instead of displaying all 7 or is this something that would be better accomplished with an sns.bargraph or just plain matplotlib?

Answer 1

import seaborn as sns titanic = sns.load_dataset("titanic") sns.countplot(y="deck", hue="class", data=titanic, palette="Greens_d",               order=titanic.deck.value_counts().iloc[:3].index) 

Answer 2

Just adding real example instead of toy dataset. Assuming you have Pandas Data Frame name training_var and you want to display top 10 'Gene' column counts 'order=' bit should look as follows:

sb.countplot(x='Gene',data=training_var,order=pd.value_counts(training_var['Gene']).iloc[:10].index)
