The Linked Brushing tutorial seems to be broken. Starting from the Python-based linked brushing section, the selections no longer work (nothing happens after selecting the box region). I’m guessing some component was updated and this feature needs to be updated. This is true in both html and downloaded and used in Jupyter with latest holoviews version. I’m just starting to use Holoviews, so I’m not sure what is wrong.
The website does not have a live kernel so this will never work (it probably needs a disclaimer though). As for your local copy are you using JupyterLab and have you installed the JupyterLab extension with:
jupyter labextension install @pyviz/jupyterlab_pyviz
You’re right! thank you. A disclaimer would help, but I didn’t question the kernel issue.
