ALL software version info

(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc)

I basically followed
https://hvplot.holoviz.org/getting_started/installation.html

and installed everything with

conda create -n hvplot-env -c conda-forge -c nodefaults hvplot geoviews datashader xarray pandas geopandas dask streamz networkx intake intake-xarray intake-parquet s3fs scipy spatialpandas pooch rasterio fiona plotly matplotlib jupyterlab

Description of expected behavior and the observed behavior

Then following

https://hvplot.holoviz.org/

I tried

import hvplot.xarray
import panel as pn
import xarray as xr

da = xr.tutorial.open_dataset('air_temperature').air
w_quantile = pn.widgets.FloatSlider(name='quantile', start=0, end=1)
w_time = pn.widgets.IntSlider(name='time', start=0, end=10)

da.interactive(loc='left') \
.isel(time=w_time) \
.quantile(q=w_quantile, dim='lon') \
.hvplot(ylabel='Air Temperature [K]', width=500)

But this is on a .py file on a JupyterLab that I am running using the console for editor which pops up a notebook that is used to run the code.

Complete, minimal, self-contained example code that reproduces the issue

The code was provided in the previous session.

Hi @iuryt,

Thanks for opening this issue. I'm not sure I ever used the Code console in Jupyter Lab :) ! I also thought I was just a regular IPython console, it turns out it's more than that as you can't display HoloViews plots in an IPython terminal or Qt console.

I'm moving this issue to another repository that holds the extension responsible for the interactivity you usually get in a notebook. Note that I'm not sure it's going to be possible to support having interactivity in the Jupyter Lab Code Console, so until then the workaround is to directly work in a notebook instead of in the Code Console.

I moved this issue from hvPlot to here. I have no clue whether supporting full interactivity in the Jupyter Lab Code Console is possible 🙃

• Console code: https://github.com/jupyterlab/jupyterlab/tree/main/packages/console
• Console extension code: https://github.com/jupyterlab/jupyterlab/tree/main/packages/console-extension

[iuryt]

Thanks! I am using the notebook now, but it took a while for me to realize that was not a problem on my browser. Haha

[maximlt]

Yes, maybe there's a way to detect when the code is executed from within the Code Console and log/warn about the limited support.
