Cannot configure annotator for plot when groups are in y axis

[jonpedros]

I think I might be doing something wrong here, but...

import seaborn as sns
from statannotations.Annotator import Annotator

iris = sns.load_dataset("iris")
iris = pd.melt(iris, "species", var_name="measurement")
pair_list = [(('sepal_length', 'setosa'),
              ('sepal_length', 'versicolor'),
              ('sepal_length', 'virginica')),
             (('sepal_width', 'setosa'),
              ('sepal_width', 'versicolor'),
              ('sepal_width', 'virginica')),
             (('petal_length', 'setosa'),
              ('petal_length', 'versicolor'),
              ('petal_length', 'virginica')),
             (('petal_width', 'setosa'),
              ('petal_width', 'versicolor'),
              ('petal_width', 'virginica'))]
petal_ax = sns.pointplot(
    data=iris, x="value", y="measurement", hue="species",
    join=False, dodge=.8 - .8 / 3, palette="dark",
    markers="d", scale=.75, errorbar=None
)
annotator = Annotator(ax=petal_ax, 
                        pairs=pair_list, 
                        data=iris, 
                        y="measurement",
                        x="value",
                        hue="species", 
                        order=['sepal_length', 'sepal_width', 'petal_length', 'petal_width'],
                        hue_order=['setosa', 'versicolor', 'virginica'])
annotator.configure(test='Mann-Whitney', text_format='star', loc='outside')
annotator.apply_and_annotate()

Hello! I can see that your pair_list is a list of 3-tuples, which isn't the expected format to define the groups to compare. It should look like this instead:

pair_list = [
    (('sepal_length', 'setosa'), ('sepal_length', 'versicolor')),
    (('sepal_length', 'virginica')), ('sepal_width', 'setosa')),
    (('sepal_width', 'versicolor'), ('sepal_width', 'virginica')),
    (('petal_length', 'setosa'), ('petal_length', 'versicolor')),
    ...
