限制seaborn计数图中显示的组数? [英] limit the number of groups shown in seaborn countplot?

问题描述

是否可以仅在a sns.countplot()中显示前/后 n 个组?

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

使用Seaborn网站上的示例

Using an example from the seaborn website,

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

是否有任何简单(甚至相对简单)的方法可以将此图限制为仅3个套(组)而不是全部显示7个图?这是否可以通过sns.bargraph或仅使用matplotlib更好地完成?

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?

推荐答案

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)
