go.Treemap not rendering + branchvalues total

đź“Š Plotly Python

Hi all, I have an issue with go.Treemap that I think is related to go.Treemap not rendering - Python.

Here’s a minimal working example:

I have 4 parents (i don’t know their value a priori) so I set it to zero. Each parent has 2 children.

import plotly.graph_objects as go

# Define the data structure
labels = [
    # Parent nodes
    "Parent A",
    "Parent B",
    "Parent C",
    "Parent D",
    # Children for Parent A
    "Child A1",
    "Child A2",
    # Children for Parent B
    "Child B1",
    "Child B2",
    # Children for Parent C
    "Child C1",
    "Child C2",
    # Children for Parent D
    "Child D1",
    "Child D2",
]

parents = [
    # Parents (root level)
    "",
    "",
    "",
    "",
    # Children's parents
    "Parent A",
    "Parent A",
    "Parent B",
    "Parent B",
    "Parent C",
    "Parent C",
    "Parent D",
    "Parent D",
]

# Values for each node
values = [
    # Parent values (will be ignored when using branchvalues="total")
    0,
    0,
    0,
    0,
    # Children values
    50,
    100,
    75,
    25,
    40,
    60,
    30,
    70,
]

fig = go.Figure(
    go.Treemap(
        labels=labels,
        parents=parents,
        values=values,
        branchvalues="total", 
    )
)


fig.show()

This doesn’t render at all and I believe this is due to branchvalues="total", .

Now if I set `branchvalues=“remainder” I get:

Which looks right, but the displayed hovervalue is 0 for the parents.

While I guess this may be the expected behaviour, I would like to know if there is a way to not have to pre-calculate the value of the parents. I tried setting it as None but that as well simply doesn’t render.

This sort of thing works perfectly with plotly express Treemap, but I would like to be able to use this more generic version to avoid having to use rectangular dataframes.

Thanks in advance!
