[bokeh] Update/Add a figure in real time on bokeh server

birdsarah_continuumAug 08, 2016 #1

To update something using the server change it’s property:

e.g.
from bokeh.layouts import row
row_1 = row(children=[hist1, hist2])

Then later

row_1.children = [hist_1_new, hist_2_new]

However, I believe there's a bug where you can't update nested

children. So in your case of a column of rows, you may have a
problem.

It works in the notebook because it's completely re-rendering the

whole thing I believe.

      I am writing a program which visualizes a set of histograms
on bokeh and updates them in real time. I want to be able to
add/take away variables from the program which will cause
either additional histograms to appear or existing histograms
to disappear.

I’ve got the first part running using the command

session = push_session(curdoc())

to set up the server document and

session.show(Column(*rows_of_histograms))

      which causes the histograms to show up on a browser window.
As I update the data to the histograms they display on the
browser as I expected. However, when a new variable is
instantiated in the program and I need a new histogram to be
displayed. I’ve set the program to clear the display and show
the figures again so it calls

session.show(Column(*new_rows_of_histograms))

      However, this doesn't seem to work. It works on the
notebook if I use output_notebook and push_notebook() but
doesn’t work on the server. Can anyone tell me what I’m doing
wrong or give me an alternative way to do this?

Thanks!
