seaborn violin plot, how can I set labels?

Question

I'm plotting a list of vectors as a sequence of violin plots. I'd use a pandas dataframe, but the lists are unequal lengths.

This works: python g = sns.violinplot (data=res, cut=0, inner='box')

where 'res' is a list of lists (each a vector of floats), where each vector should be turned into a violin. It is.

but the x axis is just labeled '0,1,2...'. Adding the parameter 'names=[0,1,2...]' is silently ignored.

Answer 1

You can use the .set_xticklabels() method:

ax = sns.violinplot(data=res, cut=0, inner='box')
ax.set_xticklabels(['a','b','c'...])

Example:

import numpy as np, seaborn as sns

res = [i for i in (np.random.randn(3, 25))]
ax = sns.violinplot(data=res, cut=0, inner='box')
ax.set_xticklabels(['a','b','c'])

Results in:

Answer 2

ax = sns.violinplot(data=rescaledX,   inner='quartile')
ax.set_xticklabels(bos.columns)
ax.set_title('Distribution of Boston Housing Data Set', fontsize=16);
