Worth pointing out this issue, of which I found other traces searching for a solution:
Since installing bokeh 8.x (and including 9.0), any plot involving the bokeh-server does not render data. Examples include data_tables_server.py and linked_tap_server.py. The widgets work (e.g. in data tables), but the charts are empty of data*. For clarity, I launch the server through bokeh.server.run() as per scripts/bokeh-server-script.py
This apparently extends to Python 2 and Python 3, and to several browsers, according to this user in SO.
Has anybody encountered, and solved, this issue?
* I presume tis is not the old “zoom in” bug I found mentioned here as I cannot even see the grid of the plots
