I'm using plotly to visualise measurement data from inside a Raspi 3b, serving the result with Dash and Flask, which worked beautifully until plotly v5.24.1.

Now, with plotly v6.1.2 I only see empty graphs. Explicitely setting line parameters changes nothing.

This is plotly-relevant code:

import plotly.graph_objs as go
 fig = go.Figure(
 data=[go.Scatter(x=x, y=y, mode='lines', name='test')],
 layout=go.Layout(
 xaxis=dict(title='time', rangeslider=dict(visible=True)),
 yaxis=dict(title='data'),
 margin=dict(l=40, r=20, t=30, b=40),
 hovermode='closest',
 )
 )
