shall "legend_example" work on Jupyterlab-0.27.0, holoviews-1.8.4, bokeh-0.12.9 ?

[stonebig]

this example works on Notebook, but not in jupyterlab-0.27.0. Is it normal (could be me ?) https://github.com/ioam/holoviews/blob/master/examples/gallery/demos/bokeh/legend_example.ipynb

[philippjfr]

We still haven't done any testing or compatibility work on JupyterLab. Have you tested other examples or is it specific to this example?

[stonebig]

well, now testing the same on "notebook" with matplotlib-2.1.0rc1, it doesn't go very much better

well, it's just that now that I have (at last) bokeh and ipyleaflet working on jupyterlab, I tried to be a little more adventurous, by testing your most recently refreshed example. and so I have also an issue on fresh notebook-5.1.0 / matplotlib-2.1.0rc1 / seaborn-0.8.1 / holoviews-1.8.4

[philippjfr]

It looks like you're running the bokeh example in matplotlib, does the corresponding matplotlib version of the notebook work?

[stonebig]

I did run the "legend_example" example in matplotlib/bokeh notebook/jlab. Apparently, of the 4 combinations, only the bokehnotebook combination works in my particular configuration.

[philippjfr]

What I mean is that it looks like you simply ran the bokeh version and switched to the matplotlib extension. There are backend specific versions of each notebook, e.g. notice how the example you ran is located here:

examples/gallery/demos/bokeh/legend_example.ipynb

There is an equivalent example for matplotlib in, which should work:

examples/gallery/demos/matplotlib/legend_example.ipynb

[stonebig]

oups! I didn't notice the last cell was different. so Matplotlib Notebook and Matplotlib Jupyterlab are ok

[philippjfr]

Going to close this since we have an existing issue for JupyterLab compatibility.
