How to specify plotly's `config` attribute?

Hi!

Currently, It is impossible to change any configuration options (e.g., adding or removing buttons from the modebar) when rendering a Plotly Figure using shinywidgets. Any chance this can be supported?

Unfortunately this is a limitation of the underlying plotly FigureWidget, so an official fix would have to come them plotly/plotly.py#1074

That said, there are CSS workarounds you can do to hide stuff from the modebar. I've done this a few times to hide the modebar completely. If you're curious how to do that, I can get a minimal example for you.

Thank you for your response @cpsievert

I have tried hiding stuff using CSS myself, but couldn't get it to work. A small example would be very helpful!

Actually, with the latest releases of plotly and shinywidgets, you can now specify a _config on a FigureWidget() object.

Still not totally ideal (maybe @render_plotly() could handle this via a config argument?), but at least this works for now:

import plotly.express as px
import plotly.graph_objects as go
import shiny.express

from shinywidgets import render_plotly

@render_plotly
def plot():
    fig = px.histogram(
        px.data.tips(),
        x="total_bill",
    )

    w = go.FigureWidget(fig)
    w._config["displayModeBar"] = False
    return w

Thanks!

Not sure why but your implementation does not work for me using shiny core.

This works for me:
w._config = fig._config | {"showModeBar": False}

Can you provide a complete example and double-check you have shinywidgets>=0.5 and plotly>=6.0?

Maybe we should allow returning config as part of a tuple

render_plotly
def plot():
    fig = px.histogram(
        px.data.tips(),
        x="total_bill",
    )

    return fig, {"displayModeBar": False}

It's the same syntax Dash uses, which also means that LLMs are likely to guess it
