Hope this works @Elpiro @jonmmease


Adds a new optional color_threshold argument to the create_dendrogram function to customize the dendrogram "cut height" at which clusters are separated.

This work was initially started by @Elpiro in #1075


Examples

import plotly.graph_objs as go
import plotly.figure_factory as ff
import numpy as np

X = np.random.rand(15, 15)

Default behavior

dendro = ff.create_dendrogram(X)
fig = go.FigureWidget(dendro)
fig

newplot

With a color threshold

dendro = ff.create_dendrogram(X, color_threshold=1.6)
fig = go.FigureWidget(dendro)
fig

newplot 1

Thanks @paulamool and @Elpiro, I'll take a look in detail soon, but this looks like a great addition and we should be able to get this into 3.4.0.
