Conditional means with observations#


seaborn components used: set_theme(), load_dataset(), despine(), stripplot(), pointplot(), move_legend()

import seaborn as sns
import matplotlib.pyplot as plt

iris = sns.load_dataset("iris")

# "Melt" the dataset to "long-form" or "tidy" representation
iris = iris.melt(id_vars="species", var_name="measurement")

# Initialize the figure
f, ax = plt.subplots()
sns.despine(bottom=True, left=True)

# Show each observation with a scatterplot
    data=iris, x="value", y="measurement", hue="species",
    dodge=True, alpha=.25, zorder=1, legend=False,

# Show the conditional means, aligning each pointplot in the
# center of the strips by adjusting the width allotted to each
# category (.8 by default) by the number of hue levels
    data=iris, x="value", y="measurement", hue="species",
    dodge=.8 - .8 / 3, palette="dark", errorbar=None,
    markers="d", markersize=4, linestyle="none",

# Improve the legend
