How can I update figure config without calling figure.show(config=config_dict)?

I’m working on a python web app which displays a plotly figure. If I call figure.show(config=config) this will open a new window, and not update the config of the figure that I have in the UI (I guess the case would be the same for a Dash app).

I’ve seen examples of some parts of config that can be updated using, e.g. update_layout(), but I want to change the ‘toImageButtonOptions’ config, and I’ve not been able to find a way to do that. The end goal is to increase the resolution of the png image that a user can download using the camera icon on the modebar.

Example

import plotly.graph_objects as go

fig = go.Figure()

fig.add_scatter(x=[1, 2, 3], y=[4, 5, 6])

# config to increase the resolution of the exported png
config = {
    'toImageButtonOptions': {
        'format': 'png',
        'filename': 'export_name',
        'height': 900,
        'scale': 6
    }
}

# How to update the config for the figure, without calling fig.show(config=config)

Hi @reka ,

If you use Dash, you can set config inside dcc.Graph object .

app.layout = dcc.Graph(id = 'graph-img',figure={}, config={'displayModeBar': True,'displaylogo': False})

Hope this help.

Thanks for the suggestion, but not using Dash.
