bokeh.core.state¶
Encapsulate implicit state that is useful for Bokeh plotting APIs.
Note
While State
objects can also be manipulated explicitly, they are
automatically configured when the functions output_file()
,
etc. from bokeh.io are used, so this is not necessary under
typical usage.
Generating output for Bokeh plots requires coordinating several things:
Document
- Groups together Bokeh models that may be shared between plots (e.g., range or data source objects) into one common strucure.
Resources
- Control how JavaScript and CSS for the client library BokehJS are included and used in the generated output.
It is possible to handle the configuration of these things manually, and some
examples of doing this can be found in examples/models
directory. When
developing sophisticated applications, it may be necessary or desirable to work
at this level. However, for general use this would quickly become burdensome.
This module provides a State
class that encapsulates these objects and
ensures their proper configuration in many common usage scenarios.
-
class
State
[source]¶ Manage state related to controlling Bokeh output.
-
output_file
(filename, title='Bokeh Plot', mode='cdn', root_dir=None)[source]¶ Configure output to a standalone HTML file.
Calling
output_file
not clear the effects of any other calls tooutput_notebook
, etc. It adds an additional output destination (publishing to HTML files). Any other active output modes continue to be active.Parameters: - filename (str) – a filename for saving the HTML document
- title (str, optional) – a title for the HTML document
- mode (str, optional) –
how to include BokehJS (default:
'cdn'
)One of:
'inline'
,'cdn'
,'relative(-dev)'
or'absolute(-dev)'
. SeeResources
for more details. - root_dir (str, optional) –
root dir to use for absolute resources (default: None)
This value is ignored for other resource types, e.g.
INLINE
or``CDN``.
Warning
The specified output file will be overwritten on every save, e.g., every time
show()
orsave()
is called.
-
output_notebook
()[source]¶ Generate output in Jupyter notebook cells.
Calling
output_notebook
not clear the effects of any other calls tooutput_file
, etc. It adds an additional output destination (publishing to notebook output cells). Any other active output modes continue to be active.Returns: None
-
reset
()[source]¶ Deactivate all currently active output modes and set
curdoc()
to a fresh emptyDocument
.Subsequent calls to
show()
will not render until a new output mode is activated.Returns: None
-
file
¶ A dict with the default configuration for file output (READ ONLY)
The dictionary value has the following form:
{ 'filename' : # filename to use when saving 'resources' : # resources configuration 'title' : # a title for the HTML document }
-
notebook
¶ Whether to generate notebook output on show operations. (READ ONLY)
