Hi Bryan,
I was trying this with bokeh 0.12.5 using the example from “bokeh/examples/plotting/file/legend.py” with no success.
from bokeh.document import Document
from bokeh.plotting import show, output_file, figure
from bokeh.layouts import gridplot
import numpy as np
output_file(‘test3.html’)
x = np.linspace(0, 4*np.pi, 100)
y = np.sin(x)
TOOLS = “pan,wheel_zoom,box_zoom,reset,save,box_select”
p1 = figure(title=“Legend Example”, tools=TOOLS)
p1.circle(x, y, legend=“sin(x)”)
p1.circle(x, 2y, legend="2sin(x)“, color=“orange”)
p1.circle(x, 3y, legend="3sin(x)”, color=“green”)
p2 = figure(title=“Another Legend Example”, tools=TOOLS)
p2.circle(x, y, legend=“sin(x)”)
p2.line(x, y, legend=“sin(x)”)
p2.line(x, 2y, legend="2sin(x)", line_dash=(4, 4), line_color=“orange”, line_width=2)
p2.square(x, 3y, legend="3sin(x)“, fill_color=None, line_color=“green”)
p2.line(x, 3y, legend="3sin(x)”, line_color=“green”)
output = gridplot(p1, p2, ncols=2, plot_width=400, plot_height=400)
doc = Document()
doc.add_root(output)
t = doc.to_json()
del doc
newdoc = Document()
newdoc.from_json(t)
show(newdoc)
``
I get an
AttributeError: ‘Document’ object has no attribute ‘references’
``
Would you be able to point me to an example of how to implement this functionality?

Hi,
Bokeh already has specialized serialization requirements, in order to communicate between Python Bokeh and BokehJS. I would encourage you to use the existing JSON representation that Bokeh itself generates, and not try to use pickle. I have very little confidence that pickle would currently work, or that it could easily be made to work.
The Documents class has methods to generate and load JSON:
[http://bokeh.pydata.org/en/latest/docs/reference/document.html#bokeh.document.Document.to_json](http://bokeh.pydata.org/en/latest/docs/reference/document.html#bokeh.document.Document.to_json)
[http://bokeh.pydata.org/en/latest/docs/reference/document.html#bokeh.document.Document.from_json](http://bokeh.pydata.org/en/latest/docs/reference/document.html#bokeh.document.Document.from_json)
You should be able to use these to save or replace curdoc()
Thanks,
Bryan

Does anyone have any experience with pickling bokeh plot objects, saving them to a file or database , retrieving them and perhaps using them again to update the data sources or integrate the object with a bokeh server?
I would be grateful for some advice or resources on how to perform these actions.
I generate a lot of plot objects from reports and would like to save them when working with my web application. Any ideas?
Thank you
