Session error in updated bokeh_plots.py for streaming plots example

Hi,

I am trying to modify the “Streaming Plots” example to run on Bokeh 0.6.1 by removing the JSON aspects and plotting data directly from the SQLite database. I’m able to get a static plot to appear from the database but am having trouble getting the live update to work. In the last part of the bokeh_plots.py script I get the following error:

Traceback (most recent call last):

File “bokeh_plots_v3.py”, line 107, in

session().store_obj(ds)

TypeError: ‘Session’ object is not callable

This line should be replaced with cursession().store_objects(ds). See [1] as an up-to-date example. Given this kind of errors, we may need to invest more in proper deprecation cycle and/or add migration guide.

This appears to be the command to update the data in the existing graph. I’ve attached my version of the bokeh_plots.py script in case that helps.

Thanks!

James

P.S. I’m pretty jazzed about using Bokeh in a number of projects and it would be great to solve this issue so that I can get the live streaming aspect working. I’ll then be able to update my current “intro” videos on Bokeh running on the Raspberry Pi and Wandboard (http://youtu.be/Y_bnjawTLxY and http://youtu.be/da_loaEaytc)
