Customizing other attributes¶

Changing default values¶

Default link, node and axis label values can be changed by providing customized data classes to idendrogram constructor. For a full list of properties of each data class, see Data Containers.

from idendrogram.containers import AxisLabel, ClusterLink, ClusterNode
from dataclasses import dataclass, field

@dataclass
class MyAxisLabel(AxisLabel):
    labelAngle: int = -180

@dataclass
class MyNode(ClusterNode):
    radius: float = 5
    _default_leaf_radius: float = 10    

@dataclass
class Mylink(ClusterLink):
    strokewidth: float = 0.5
    strokedash: list = field(default_factory=lambda: [6, 2])
    
idd = idendrogram.idendrogram(
    axis_label_factory=lambda x:  MyAxisLabel(**x),
    node_factory= lambda x: MyNode(**x),
    link_factory= lambda x: Mylink(**x))

idd.set_cluster_info(cl_data)
dendrogram = idd.create_dendrogram()
to_altair(dendrogram=dendrogram, height=200, width=629)

from idendrogram.containers import AxisLabel, ClusterLink, ClusterNode from dataclasses import dataclass, field @dataclass class MyAxisLabel(AxisLabel): labelAngle: int = -180 @dataclass class MyNode(ClusterNode): radius: float = 5 _default_leaf_radius: float = 10 @dataclass class Mylink(ClusterLink): strokewidth: float = 0.5 strokedash: list = field(default_factory=lambda: [6, 2]) idd = idendrogram.idendrogram( axis_label_factory=lambda x: MyAxisLabel(**x), node_factory= lambda x: MyNode(**x), link_factory= lambda x: Mylink(**x)) idd.set_cluster_info(cl_data) dendrogram = idd.create_dendrogram() to_altair(dendrogram=dendrogram, height=200, width=629)

Postprocessing¶

Any attribute of a node or a link can also be adjusted after the dendrogram object has been created. Here's an example where radii of nodes are adjusted based on number of observations they represent.

In [4]:

idd = idendrogram.idendrogram()
idd.set_cluster_info(cl_data)
dendrogram = idd.create_dendrogram()

for n in dendrogram.nodes:
    obs_count = int(idendrogram.callbacks.counts(cl_data, n.id))
    n.radius = obs_count / 10


to_altair(dendrogram=dendrogram, height=200, width=629)

idd = idendrogram.idendrogram() idd.set_cluster_info(cl_data) dendrogram = idd.create_dendrogram() for n in dendrogram.nodes: obs_count = int(idendrogram.callbacks.counts(cl_data, n.id)) n.radius = obs_count / 10 to_altair(dendrogram=dendrogram, height=200, width=629)
