Plotly gives an empty field as output in jupyter lab

Question

I\'m using plotly at jupyter lab, but I\'m getting a blanked output. I\'m having exactly the same problem described here: plotly.offline.iplot gives a large blank field as its o

Answer 1

To properly display the plotly offline graphs in JupyterLab,

Step 1: We need to first install the plotly-extension for JupyterLab:

$ jupyter labextension install @jupyterlab/plotly-extension

(Note that the above step requires Node.js >= 4, if Node.js is not available on your OS, install it from its Official Website.)

Step 2: Check the status after the installation of @jupyterlab/plotly-extension:

$ jupyter labextension list 
JupyterLab v0.35.5
Known labextensions:
   app dir: /Users/yourname/anaconda3/share/jupyter/lab
        @jupyterlab/plotly-extension v0.18.2  enabled  OK

Build recommended, please run `jupyter lab build`:
    @jupyterlab/plotly-extension needs to be included in build

Step 3: Follow the suggestion, re-build the JupyterLab with its newly installed labextensions:

$ jupyter lab build

After these, restart JupyterLab, and set plotly.offline.init_notebook_mode(connected=True) at the start of each notebook session, then plotly.offline.iplot should correctly display the plots in the notebook.
