How to source.push_notebook() using the new bokeh.io.push_notebook API?

source.push_notebook() used to work before 0.11.0. Now it is replaced with bokeh.io.push_notebook, but there are zero examples on how to update a particular plot:

http://bokeh.pydata.org/en/0.11.1/docs/reference/io.html#bokeh.io.push_notebook :

push_notebook(document=None, state=None, handle=None)¶
Update the last-shown plot in a Jupyter notebook with the new data or property values.

Parameters:

• document (Document, optional) – A Document to push from. If None, uses curdoc().
• state (State, optional) – A Bokeh State object
  Returns:
  None

Examples

Typical usage is typically similar to this:

from [bokeh.io](http://bokeh.io) import push_notebook

# code to create a plot

show(plot)

plot.title = "New Title"

# This will cause the title to update
push_notebook()

What’s a document? What’s a handle?

If I pass the result of figure() or p.circle() to either handle or document I get errors, i.e. these are not the objects expected by bokeh.io.push_notebook.

I’m happy to PR to update the documentation, but need to figure out what a document is and what a handle is.

Ok, will have to answer my own question:

handle = show(plot)
push_notebook(handle=handle)

That works. Multiple plots in a notebook update on arrival of an event affecting a particular plot. Sweet.
