Box plot

whis sets how many IQRs past q1/q3 the whiskers reach before a point counts as a flier (matplotlib’s own default is 1.5; wider here so fewer of this dataset’s points are flagged).

Live figure — pick a tool, then zoom, pan, point-pick or annotate. Nothing is active until a tool is selected.

import numpy as np
import plotpress

rng = np.random.default_rng(5)
data = [rng.normal(loc, 1.0, 200) for loc in (0, 1, 2, 1.5)]
fig, ax = plotpress.subplots()
ax.boxplot(data, whis=2.5)
ax.set_title("Box plot")
fig.tight_layout()
