Manually specifying labels

By default, data point labels are their node IDs. They can be changed using the labels parameter.

import plotly.graph_objects as go
import plotly.io as pio
import scipy

from pdendro import attach_dendrogram

X = [[0.0], [1.0], [3.0], [6.0]]
Z = scipy.cluster.hierarchy.linkage(X)

fig = go.Figure()
attach_dendrogram(fig, Z, labels=["a", "b", "c", "d"])
pio.show(fig)
