Bokeh exampleΒΆ
This example demonstrates the use of bokeh in the sphinx-nbgallery.
The example is taken from the bokeh-notebook gallery to demonstrate the
use bokeh. For the sphinx-nbgallery, you have to do 3 additional
modifications in the example_gallery_config
of your conf.py
:
You have to set the
insert_bokeh
configuration value because we need additional style sheets and javascript filesNote, that, since the
output_notebook
function needs some time, we recommend to use thedont_preprocess
configuration value for this notebook.We cannot estimate a thumbnail figure for a notebook not using matplotlib. So you should provide it using the
thumbnail_figure
metadata key (as it has been done for this notebook)
