Display a Phylogenetic Tree with a Square Dendrogram Style¶

We use a tree saved in json format from a likelihood function analysis of a non-stationary model. The tree was derived such that the the branch lengths are now “ENS”.

[1]:

from cogent3.app import io

reader = io.load_json()

ens_tree = reader("../data/GN-tree.json")
fig = ens_tree.get_figure(width=600, height=600)
fig.show()

Changing scale bar placement¶

[2]:

fig.scale_bar = "top right"
fig.show()

Colouring a set of edges¶

[3]:

fig.style_edges("AfricanEl", tip2="Manatee", legendgroup="Afrotheria",
                line=dict(color="magenta"))
fig.show()

With Contemporaneous Tips¶

[4]:

fig.contemporaneous = True
fig.show()
