I upgraded to the most recent dev distrbution of bokeh. I am now looking through some of the examples and I find that in some cases I get a blank browser window.
This happens for:
buttons_server.py
timeout_stocks.py
and stocks
My configuration is Windows 8 64, Anaconda 32 bit 2.7 latest package, Bokeh 0.11 dev.
What am I missing here?
Hi Redraven,
I don't think you are missing anythign, but Bokeh 0.11dev is pre-release, and there are still issues to resolve on windows:
https://github.com/bokeh/bokeh/issues/3305
None of the Bokeh core devs use Windows regularly to my knowledge, it would be great to get some new contributors that are normally Windows users to help with maintaining Windows support. In any case, I hope to have these issues resolved in the next week.
Thanks,
Bryan

Thanks Bryan. Well Im not entirely sure I am at the level that I can contribute but I will try to add what I can to the process.
I’ve gotten quite a bit of traction here thanks to you and Fabio. One last questions here, Is there a tool that lets you draw on the plot? Similar to the way you can write a drawing app using the Tkinter Canvas?
What I mean by this is, Bokeh has the hover tool and the selection tool. Is it possible to collect the mouse coordinates and to then plot a line plot over them?

So Ive been digging a little on my question here and it looks like what I need is a CustomJS interaction. Something like this:
// get data source from Callback args
var data = source.get('data');
/// get coordinates from cb_data parameter of Callback
var geometry = cb_data['data'];
/// Somehow obtain the X,Y coordinates of the mouse?
var x = data['x']???
var y = data['y']???
/// update data source with new series of coordinates
data['x'].push(x);
data['y'].push(y);
// trigger update of data source
source.trigger('change');
Is this about right? What can I pull out from cb_data? I’m not familiar with JavaScript so I welcome any comments of suggestions here.

cb_data is just a little dict that the callback can pass data specific to it back to the callback function (i.e., it's specific to each kind of callback type) For instance here is some code that makes a selection on one plot zoom on another:
x = np.linspace(0, 10, 500)
y = np.sin(x) + np.random.normal(size=500)
p1 = figure(plot_width=800, plot_height=250, min_border=0)
p1.line(x, y)
p2 = figure(plot_width=800, plot_height=250, min_border=0)
p2.line(x, y)
callback = CustomJS(args=dict(p1=p1), lang="coffeescript", code="""
g = cb_data.geometry
p1. get('frame').get('x_ranges').default.set({start: g.x0, end: g.x1})
""")
p2.add_tools(BoxSelectTool(callback=callback, dimensions=['width']))
show(vplot(p1, p2))
The common BokehJS actions that you might perform in a CustomJS callback need to be documented better. That's my focus for the next week so I will try to include more about this in some of that work.
