Hi HN,

This is Jon from the release announcement. AMA!

Hi Jon, Thanks for the great release! Your post mentions support for JupyterLab, but getting Plotly working in JupyterLab is not working smoothly at the moment (see https://github.com/jupyterlab/jupyter-renderers/issues/132). Is this something you guys are looking into?

I haven't looked into this specifically. Using the FigureWidget approach in 3.0.0 doesn't actually require the current @jupyterlab/plotly-extension. It's all contained in the new plotlywidget extension.

Oh, that's a great improvement in and of itself then. Thanks!

BTW, I got a GitHub notification of a comment that you were having trouble installing it. But I can't find the comment in GitHub itself.

Ah ya, I realized afterwards from more Googling that this is a global problem in the jupyterlab extension ecosystem when using node 10. Since it's already been worked on in other issues, I deleted my comment.

Is it possible to have the lasso tool return a list of selected data points?

Yes! You use the trace.on_selection method to register a callback function. Here's an example: https://github.com/jonmmease/plotly_ipywidget_notebooks/blob...

That's f'n awesome. Many thanks!

Hi Jon,

Just want to say I absolutely love plotly. It's made data science and visualization fun again. Thank you for all your hard work!

Sure thing! But full disclosure, I wasn't actually involved in any of the versions of plotly.py before 3.0.0 :-)

Hopefully 3.0.0 will be even more fun!

Plotly is awesome, but it can be really slow when loading from cold with a shiny app. Big fan of it with ggplot.
