How to label a violin plot on Seaborn?

Question

I'm trying to change the labels in a violin plot on Seaborn. I wanna change the NU_NOTA_CN, NU_NOTA_CH, NU_NOTA_LC, NU_NOTA_MT and NU_NOTA_REDAÇÃO, and TP_ESCOLA, and the 2 and 3.

import pandas as pd
import numpy as np
import seaborn as sns

fig_dims = (10, 8)
fig, ax = plt.subplots(figsize=fig_dims)
sns.boxplot(x="DISCIPLINA", y="NOTA", hue="TP_ESCOLA", data=publica_privada_pivot)  
plt.show()

plt.clf()
plt.close()

Answer 1

You can use the set_xticklabels

f, ax = plt.subplots()
sns.boxplot(x="DISCIPLINA", y="NOTA", hue="TP_ESCOLA", data=publica_privada_pivot, ax=ax)
ax.set_xticklabels([...]) # list of strings

In addition, you can use get_xticklabels , for example.

xticklabels = [t.get_text() for t in ax.get_xticklabels()]
xticklabels = [t.replace('NU_', '').replace('_', ' ').title()
ax.set_xticklabels(xticklabels)

Answer 2

tips = sns.load_dataset("tips")
foo = sns.boxplot(x="day", y="total_bill", data=tips)
plt.xticks([0, 1, 2, 3], ['x1', 'x2', 'x3', 'x4'])
plt.show()

The number of unique values in 'day' column (ie cardinality of the feature) should be the length of the lists passed to plt.xticks() function.

matplotlib.pyplot.xticks
