Bokeh 0.12.10 graph not displayed after notebook reloaded in Docker container


I run a Docker container with Python 3.5.2/Jupyter embeded.

When I plot a graph in my notebook, the graph is displayed well, even when I close the notebook and reload it.

However, when I stop the container, restart it and load my notebook, the graph is not displayed whereas a matplotlib graph is.

Is there a way to display a graph even after a docker container stop ? Do I have to create a volume to persist some data locally ?
