Access box_select attributes set in figure

[Wall.E]

Anyway, here’s the python server side equivalent, adapted from your example.

This is working pretty great if I dismiss my need for Jupyter Lab. I can live with that for now. That is very helpful, thanks a lot.
@Bryan suggested also to try the SelectionGeometry event with box_select. That would address the original question and is worth a look, as BoxSelectTool has no issue with Jupyter Lab.
