plotly 快递森伯斯特 plot 完整空白

Question

I'm trying to plot a sunburst with plotly express, but the output is a complete blank plot. The code below is from an example showed on the plotly site . All the examples with path give me this output.

import plotly.express as px
df = px.data.tips()
fig = px.sunburst(df, path=['day', 'time', 'sex'], values='total_bill')
fig.show()

Answer 1

Do you have some negative values in your 'total_bill' field?

I found that Sunburst plot returns a blank if the column specified by the 'values' has some negative values. When I drop rows with negative values, the chart renders fine. I don't know if this is a bug though.

I'm running Plotly 5.4.0/Python 3.8.10 in WSL2 on Windows 10.

Answer 2

You are not providing valid data. This is what it should be

import plotly.express as px
data = dict(
    character=["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"],
    parent=["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve" ],
    value=[10, 14, 12, 10, 2, 6, 6, 4, 4])

fig = px.sunburst(
    data,
    names='character',
    parents='parent',
    values='value',
)

fig.show()

Enjoy!
