Functions for configuring Bokeh output.

curdoc()

Return the document for the current default state.

Returns:the current default document object.
Return type:doc
curstate()

Return the current State object

Returns:the current default State object
Return type:state
gridplot(plot_arrangement, **kwargs)

Generate a plot that arranges several subplots into a grid.

Parameters:
  • plot_arrangement (nested list of Plots) – plots to arrange in a grid
  • **kwargs – additional attributes to pass in to GridPlot() constructor

Note

plot_arrangement can be nested, e.g [[p1, p2], [p3, p4]]

Returns:a new GridPlot
Return type:grid_plot
hplot(*children, **kwargs)

Generate a layout that arranges several subplots horizontally.

output_file(filename, title='Bokeh Plot', autosave=False, mode='cdn', root_dir=None)

Configure the default output state to generate output saved to a file when show() is called.

Does not change the current Document from curdoc(). File, server, and notebook output may be active at the same time, so this does not clear the effects of output_server() or output_notebook().

Parameters:
  • filename (str) – a filename for saving the HTML document
  • title (str, optional) – a title for the HTML document (default: “Bokeh Plot”)
  • autosave (bool, optional) – whether to automatically save (default: False) If True, then Bokeh plotting APIs may opt to automatically save the file more frequently (e.g., after any plotting command). If False, then the file is only saved upon calling show() or save().
  • mode (str, optional) – how to include BokehJS (default: 'inline') One of: 'inline', 'cdn', 'relative(-dev)' or 'absolute(-dev)'. See bokeh.resources.Resources for more details.
  • root_dir (str, optional) – root directory to use for ‘absolute’ resources. (default: None) This value is ignored for other resource types, e.g. INLINE or CDN.
Returns:

None

Note

Generally, this should be called at the beginning of an interactive session or the top of a script.

Warning

This output file will be overwritten on every save, e.g., each time show() or save() is invoked, or any time a Bokeh plotting API causes a save, if autosave is True.

output_notebook(resources=None, verbose=False, hide_banner=False)

Configure the default output state to generate output in Jupyter/IPython notebook cells when show() is called.

If output_server() has also been called, the notebook cells are loaded from the configured server; otherwise, Bokeh pushes HTML to the notebook directly.

Parameters:
  • resources (Resource, optional) – How and where to load BokehJS from (default: INLINE)
  • verbose (bool, optional) – whether to display detailed BokehJS banner (default: False)
  • hide_banner (bool, optional) – whether to hide the Bokeh banner (default: False)
Returns:

None

Note

Generally, this should be called at the beginning of an interactive session or the top of a script.

output_server(session_id='default', url='default', app_path='/', autopush=False)

Configure the default output state to push its document to a session on a Bokeh server.

Sessions are in-memory and not persisted to disk; in a typical production deployment, you would have a fresh session ID for each browser tab. If different users share the same session ID, it will create security and scalability problems.

output_server() defaults to always using the session_id "default", which is useful for running local demos or notebooks. However, if you are creating production sessions, you’ll need to set session_id to None (to generate a fresh ID) or to a session ID generated elsewhere.

File, server, and notebook output may be active at the same time, so output_server() does not clear the effects of output_file() or output_notebook(). output_server() changes the behavior of output_notebook(), so the notebook will load output cells from the server rather than receiving them as inline HTML.

Parameters:
  • session_id (str, optional) – Name of session to push on Bokeh server (default: “default”) Any existing session with the same name will be overwritten.
  • url (str, optional) – base URL of the Bokeh server (default: “default”) If “default” use the default localhost URL.
  • app_path (str, optional) – relative path of the app on the Bokeh server (default: “/”)
  • autopush (bool, optional) – whether to automatically push (default: False) If True, then Bokeh plotting APIs may opt to automatically push the document more frequently (e.g., after any plotting command). If False, then the document is only pushed upon calling show() or push().
Returns:

None

Warning

Calling this function will replace any existing server-side document in the named session.

push(session_id=None, url=None, app_path=None, document=None, state=None, io_loop=None, validate=True)

Update the server with the data for the current document.

Will fall back to the default output state (or an explicitly provided State object) for session_id, url, app_path, or document if they are not provided.

Parameters:
  • session_id (str, optional) – a Bokeh server session ID to push objects to
  • url (str, optional) – a Bokeh server URL to push objects to
  • app_path (str, optional) – Relative application path to push objects to
  • document (Document, optional) – A bokeh.document.Document to use
  • state (State, optional) – A state to use for any output_server() configuration of session or url
  • io_loop (tornado.ioloop.IOLoop, optional) – Tornado IOLoop to use for connecting to server
  • validate (bool, optional) – True to check integrity of the document we are pushing
Returns:

None

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 import push_notebook

# code to create a plot

show(plot)

plot.title = "New Title"

# This will cause the title to update
push_notebook()
reset_output(state=None)

Clear the default state of all output modes.

Returns:None
save(*args, **kwargs)

Save an HTML file with the data for the current document.

Will fall back to the default output state (or an explicitly provided State object) for filename, resources, or title if they are not provided.

Parameters:
  • obj (Document or model object) – a plot object to save
  • filename (str, optional) – filename to save document under (default: None) If None, use the default state configuration, otherwise raise a RuntimeError.
  • resources (Resources, optional) – A Resources config to use (default: None) If None, use the default state configuration, if there is one. otherwise use resources.INLINE.
  • title (str, optional) – a title for the HTML document (default: None) If None, use the default state title value, if there is one. Otherwise, use “Bokeh Plot”
  • validate (bool, optional) – True to check integrity of the models
Returns:

None

Raises:

RuntimeError

set_curdoc(doc)

Configure the current document (returned by curdoc()).

This is the document we will save or push according to output_file(), output_server(), etc. configuration.

Parameters:doc (Document) – Document we will output.
Returns:None

Note

Generally, this should be called at the beginning of an interactive session or the top of a script.

Warning

Calling this function will replace any existing document.

show(obj=None)

Immediately display a plot object.

In an IPython/Jupyter notebook, the output is displayed in an output cell. Otherwise, a browser window or tab is autoraised to display the plot object.

If both a server session and notebook output have been configured on the default output state then the notebook output will be generated to load the plot from that server session.

Parameters:
  • obj (Component object) – a plot object to display
  • browser (str, optional) – browser to show with (default: None) For systems that support it, the browser argument allows specifying which browser to display in, e.g. “safari”, “firefox”, “opera”, “windows-default” (see the webbrowser module documentation in the standard lib for more details).
  • new (str, optional) – new file output mode (default: “tab”) For file-based output, opens or raises the browser window showing the current output file. If new is ‘tab’, then opens a new tab. If new is ‘window’, then opens a new window.
Returns:

when in a a jupyter notebook (with output_notebook enabled), returns a handle that can be used by push_notebook, None otherwise.

Note

The browser and new parameters are ignored when showing in an IPython/Jupyter notebook.

vform(*children, **kwargs)

Generate a layout that arranges several subplots vertically.

vplot(*children, **kwargs)

Generate a layout that arranges several subplots vertically.
