python - Seaborn barplot with x_order: AttributeError: 'bool' object has no attribute 'sum' -


i trying plot simple barcharts seaborn.barplot(). in simplest case works well, x can vector of strings, or numbers:

import numpy np import seaborn sns import matplotplib.pyplot plt fig, ax = plt.subplots() ax = sns.barplot(np.array(['a','b','c']), y = np.array([1,2,3])) fig.tight_layout() fig.savefig('test.pdf')

to order bars in custom way, there x_order argument, list-like object indexes. if x numeric, works well:

x = np.array([2, 0, 1]) y = np.array([3, 4, 2]) sns.barplot(x, y = y, x_order = list(x.argsort()))

however, if x not numeric, gives error, if try order other numeric vector, or ordering string vector itself:

x = np.array(['b', 'c', 'a']) y = np.array([3, 4, 2]) sns.barplot(x, y = y, x_order = list(x.argsort())) sns.barplot(x, y = y, x_order = [2, 0, 1])

then error attributeerror: 'bool' object has no attribute 'sum'. haven't found this, , wondering how simple ordering properly.

x_order should list of labels, not list of indexes. in other words, in latter case want x_order=['a', 'b', 'c'].
