Rotate xtick labels in seaborn boxplot?
The question you link to uses a factorplot. A factorplot returns its own class which has a method called set_xticklabels(rotation). This is different from the set_xticklabels method of the matplotlib Axes.
In the linked question's answers there are also other options which you may use
ax = sns.boxplot(x='categories', y='oxygen', hue='target', data=df)ax.set_xticklabels(ax.get_xticklabels(),rotation=30)or
ax = sns.boxplot(x='categories', y='oxygen', hue='target', data=df)plt.setp(ax.get_xticklabels(), rotation=45)
