How to insert a sunburst in a dash app maintaing the color of it?

Dash Python
1

I created a sunburst figure with a color scale, but when inserting it into my app, it ignores the color code. How can I maintain the color??

mycode:

fig =go.Figure(go.Sunburst(
    ids = ids,
    labels= l ,
    parents= p ,
    values= v,
    branchvalues="total",
    marker=dict(
        colors=c,
        colorscale='rdylgn',),
    hovertemplate='<b>%{label} </b> <br> Total de questões: %{value}<br> Taxa de preenchimento: %{color:.0f} %',
    ))
fig.update_layout(margin = dict(t=0, l=0, r=0, b=0))
fig.show()

graph = dcc.Graph(figure = fig)

layout=[   
    graph
    ]
app.layout = html.Div(children = layout
)

app.run_server()

Hi @vialeca welcome to the forum! Humm, this should not happen. Could you please post here a standalone code reproducing the problem (you might have to use dummy data, or upload you data somewhere)? Thanks!

Just as a side note: you should not do fig.show in a Dash app, because the way the figure is shown is handled by dcc.Graph.

and my data is an access data base with the info.

I have no idea why, but it looks like it is ignoring the maker attribute

found a solution, just reinstalled the library and everything is fine now
