I am using Bokeh with IPython/Jupyter notebooks. I noticed that dataSource.push_notebook() calls only update the plot if I execute them from a codecell. I want to run push_notebook() through Javascript, i.e., IPython.notebook.kernel.execute(‘dataSource.push_notebook()’). Doing that, however, leaves the bokeh plot unchanged (lines do not update) – how could I make such a call properly?
I am facing the same issue also. Did you manage to find a solution ?

push_notebook() currently constructs a snippet of JS to update the data, and then uses the notebook's HTML publication to execute this JS in the browser (causing the BokehJS data source to get updated). I'm not sure that executing in the kernel like this is ever going to be able to be made to work, but perhaps someone expert on IPython can chime in.
A better solution would use the IPython widget protocol to update data sources, and this has been discussed. But we are currently stretched thin on other development priorities. If anyone wanted to try and tackle this feature we would be glad to offer assistance.
Alternatively, we will be previewing a completely new, radically simpler bokeh server in the next month or so, and that would be another option.

Nop, because if you use IPython.notebook.kernel.execute, you are not getting back the display representation which in turn executes the JS necessary to trigger the update… but if you are in the JS, you can probably directly interact with Bokeh… otherwise, from the python side the option that Bryan already mentioned are probably the best to follow…

thanks.
indeed interacting with Bokeh directly from JS works. simply by executing the same piece of code that push_notebook is running:
model_id = Bokeh.Collections(‘ColumnDataSource’).models[0].id;
var ds = Bokeh.Collections(‘ColumnDataSource’).get(model_id);
ds.set(‘data’, …); /// set new data value here
