Hi Sarah,
Here is a minimal code to outline the problem that I am facing. The first code block outputs a figure, the second code blocks adds a figure to the output. This works fine if you use the output_notebook() and push_notebook(). However when you use the server, the second instance does not produce plots. Any help would be appreciated.
########## CODE BLOCK 1 #############
def make_plot(x,y):
source = ColumnDataSource(data=dict(x=x, y=y))
p = figure(tools=“save, resize”,
background_fill_color=“#E8DDCB”, height=200, width=200)
p.circle(x=‘x’, y=‘y’, size=20, color=“navy”, alpha=0.5, source=source)
return p, source
from bokeh.models import ColumnDataSource, Range1d
from bokeh.plotting import figure, curdoc
from bokeh.layouts import Row
from bokeh.io import push_notebook
from bokeh.client import push_session, pull_session
import IPython.display
#output_notebook()
session = push_session(curdoc())
x = [1, 2, 3, 4, 5]
y = [6, 7, 2, 4, 5]
p1, source = make_plot(x,y)
session.show(Row(p1))
#push_notebook()
############### CODE BLOCK 2 ###################
x = [4, 2, 3, 3, 6]
y = [3, 7, 1, 3, 4]
p2, source2 = make_plot(x,y)
IPython.display.clear_output(True)
session.show(Row(p1,p2))
#push_notebook()

Okay got it. I did maintain a reference to the original Column and I still have the issue. I guess I am running into the bug. I will work on getting runnable code to show outline the issue I am I facing. Thanks!

I’m not following you.
I’m trying to say that:
1) I’d be surprised if changing the children of your column worked
- due to I bug
2) redoing mysession.show(Column(*new_ histogram_rows)) is not
the correct way to update your column of plots. The correct way is
to maintain a reference to the original column and update the
children…but see point 1.
Can you provide runnable code if you want more help?
Sincerely,
Sarah Bird

Yes this is. Sorry about that.
"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."
My nested children plots get
updated okay. The issue is when I try to add/remove new
histograms (i.e. new figures) into the plot, as I’ve more
clearly stated in this version of my issue. If I redo the
mysession.show(Column(*new_histogram_rows))
command with my new
histogram I thought it should work. Is my thinking in
correct by any chance?

Hi,
I am writing a program which has a set of
variables which keep changing and I plot their
values as histograms. I have a command
mysession = push_session(curdoc())
in order to set the session document and the
command
mysession.show(Column(*histogram_rows))
(where histogram rows is a list of Row
widgets which consist of histograms) to output
the figure on the server. When I run my program
the figure updates as expected. I want to be
able to add/remove histograms.
The way I tried to do that is to clear the
output, take the new set of histograms and plot
again as
mysession.show(Column(*new_histogram_rows))
somehow, this does not work. (Note: This
works inline on ipython notebook when I use
output_notebook() and push_notebook() instead of
the server option.) Can anyone help me identify
what I am doing wrong or suggest a better method
to get this done?
Thanks!
