Excellent, that works, thank you very much!
Funny enough this code https://discourse.bokeh.org/t/bokeh-app-does-not-display-in-jupyter-notebook-using-python-3-8-3-is-this-a-bug/5729 works for me even though it does not use push_notebook. Why would that be?
For a total beginner like me it may be helpful to add “push_notebook” as the last line in the example given under https://docs.bokeh.org/en/latest/docs/user_guide/data.html#streaming, to an unsuspecting newbie it looks like “source.stream(new_data)” is all the magic that is needed.
I came to Bokeh via Matplotlib, pyplot and pyqtgraph but they all pale in comparison to the clean interface and the streaming which is the most important for me at the moment. Now if it would also do 3D scatter plots it would be perfect
