Grouped Stacked Bar Chart - offsetgroup not being respected

[Mad-Mint]

Hello, I was trying to make a grouped stack bar chart with plotly 6.0.0 and 6.0.1 and both fail to respect offsetgroup. Running the example in the documentation does not yield the documentation's result.

import plotly.graph_objects as go

data = [
    go.Bar(
        x=['Q1', 'Q2', 'Q3', 'Q4'],
        y=[150, 200, 250, 300],
        name='New York',
        offsetgroup="USA"
    ),
    go.Bar(
        x=['Q1', 'Q2', 'Q3', 'Q4'],
        y=[180, 220, 270, 320],
        name='Boston',
        offsetgroup="USA"
    ),
    go.Bar(
        x=['Q1', 'Q2', 'Q3', 'Q4'],
        y=[130, 170, 210, 260],
        name='Montreal',
        offsetgroup="Canada"
    ),
    go.Bar(
        x=['Q1', 'Q2', 'Q3', 'Q4'],
        y=[160, 210, 260, 310],
        name='Toronto',
        offsetgroup="Canada"
    )
]

layout = go.Layout(
    title={
        'text': 'Quarterly Sales by City, Grouped by Country'
    },
    xaxis={
        'title': {
            'text': 'Quarter'
        }
    },
    yaxis={
        'title': {
            'text': 'Sales'
        }
    },
    barmode='stack'
)

fig = go.Figure(data=data, layout=layout)

fig.show()

Output:

Expected Output:

It looks like they are using different plotly.js versions but I can not find out how to update the plotly.js version to v3 with the python package

Hi @Mad-Mint - the plotly.js versioning should happen automatically. Can you please post this in https://community.plotly.com/ ? Tech support questions usually get a faster answer there. Thanks - @gvwilson

I can confirm this problem, and isolated it a bit more, on my setup.

• The plotly python package ships its own plotly js version. For 6.0.1 that is 3.0.1.
• For me, it works when running the example in an interactive python terminal. In this case, plotly.js v3.0.1 is used.
• In vscode, it seems the extension Jupyter Notebook Renderers has not been updated yet -> plotly.js v2.
  The extension was enabled on my system by default when installing jupyter for vscode.
• disabeling it solved the problem, and i still get inline renders for plotly with

import plotly.io as pio
import plotly

pio.renderers.default = "jupyterlab"
plotly.offline.init_notebook_mode()

fig = ...
plotly.offline.plot(fig)

I only tested this with vscode, but this could also be an issue with jupyter lab.
hope this helps!

I can confirm that disabling the VSCode extenstion "Jupyter Notebook Renderers" workarounds the problem.
