在Seaborn绘图中旋转Y轴分类标签？

Question

To borrow some default code with default libraries (extra helpful that you have to load the data explicitly, instead of having it polluting globals like in R...):

sns.set(style="whitegrid")
tips = sns.load_dataset("tips")
ax = sns.violinplot(y="day", x="total_bill", data=tips)

This produces the following image:

I want to rotate the day of the week labels 90 degrees such that the baseline for those labels matches the word day , also on the Y axis.

I've looked at the answers already here, but they seem primarily to deal with (1) the X axis and (2) the first-order Y-axis label (here, the day label) rather than the Y-axis sub-labels (here, the days of the week).

Answer 1

Most stackoverflow answers would recommend using ax.set_yticklabels(rotation = 90) , while this does work, it also requires you to provide the positional parameter labels (failing to provide this will give you a TypeError ). I'd recommend using plt.yticks(rotation = 90) . This is how it'd look:

import seaborn as sns
import matplotlib.pyplot as plt

sns.set(style="whitegrid")
tips = sns.load_dataset("tips")
ax = sns.violinplot(y="day", x="total_bill", data=tips)
plt.yticks(rotation = 90)
plt.show(ax)
