[FIXED] plotly basic example shows no plot in jupyter lab

Issue

I just tried to use plotly offline in a jupyter notebook (using jupyter lab). The docs gives this example:

import plotly
import plotly.graph_objs as go

plotly.offline.init_notebook_mode(connected=True)

plotly.offline.iplot({
    "data": [go.Scatter(x=[1, 2, 3, 4], y=[4, 3, 2, 1])],
    "layout": go.Layout(title="hello world")
})

I tried it and there is no chart displayed, either in Edge or Firefox.
An output cell is made in the notebook, but there is no chart.

It works if I use plotly.offline.plot rather than iplot. It works if I use the traditional jupyter notebook rather than jupyter lab.

Any ideas why it does not display?

It's plotly version 2.7.0.

Solution

Have you installed Plotly JupyterLab extension? It will not work inline without it. You can get it here: https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension

or just install via terminal: jupyter labextension install @jupyterlab/plotly-extension
