Plotly chart not showing in Jupyter notebook

You need to change init_notebook_mode call, if you want to work in offline mode.

Such that:

# Import the necessaries librariesimport plotly.offline as pyoimport plotly.graph_objs as go# Set notebook mode to work in offlinepyo.init_notebook_mode()# Create tracestrace0 = go.Scatter(    x=[1, 2, 3, 4],    y=[10, 15, 13, 17])trace1 = go.Scatter(    x=[1, 2, 3, 4],    y=[16, 5, 11, 9])# Fill out data with our tracesdata = [trace0, trace1]# Plot it and save as basic-line.htmlpyo.iplot(data, filename = 'basic-line')

Output should be shown in your jupyter notebook:

In case you want to use Jupyter lab, you will have to install the plotly jupyterlab extension: https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension.

Simple solution: jupyter labextension install jupyterlab-plotly

Restart Jupyter Lab after installing the extension.

To use a plotly version below 5.0 in Jupyter Lab make sure you have ipywidgets and plotly installed and then run the following:

jupyter labextension install jupyterlab-plotly

OPTIONAL: Jupyter widgets extension:

jupyter labextension install @jupyter-widgets/jupyterlab-manager plotlywidget

And here's the troubleshooting guide for plotly with Jupyter Lab.

As of Plotly version 5.0, I am able to create a new conda environment with Python 3.9 and then pip install plotly jupyterlab, and run Jupyter Lab and render plots without any other package or extension installs.
