Hi. Did you solve this? Having the same problem...

Hi thanks a lot.

In fact I have a little problem (that I didn't notice previously). In the sample code presented bellow each time that the push notebook is called it replot all the curve on top of the previous one (we can clearly see it from the evolution of the color of the line). How can I simply ask it to add the datapoints to the previous one without replotting everything?

Thanks!

from bokeh.io import push_notebook, show, output_notebook

from bokeh.plotting import figure

from random import randint

import time

import numpy as np

output_notebook()

p1= figure(plot_width=450,plot_height=450)

x=

y=

r1=p1.line(x,y,line_width = 2, alpha=1)

t=show(p1,notebook_handle=True)

for i in range(0,500):

x = np.append(x,i)

y= np.append(y,randint(0,12))

r1=p1.line(x,y,line_width = 2, alpha=0.2)

time.sleep(0.2)

push_notebook(handle=t)

Hi,

The push_notebook function uses the same protocol as the Bokeh sever, and e.g. the Bokeh server image_blur.py example under examples/app uses a slider to trigger an update of a 512x512 image interactively. And I have updates 1000x1000 image elsewhere. So if your total image size is 10k I would not expect any problems. If actually you mean a 10000x10000 sized image (it's not clear) then that will be too big.

Thanks,

Bryan

It works fine for me for such plot but I would like to do it with a "color plot" (a 2D numpy array) where each time that I have an array of 10000 points it updates one slice of my image by putting the height as a color. Do you know if it is possible to do such things with bokeh or I need to generate each time a new image and send it to the figure? Would holoviews work better?

However the JavaScript library that example uses for 3d is a toy library, in my opinion. If you really need 3d plots I'd say you'd probably want to find a better JS library to wrap as an extension.

Baically I am controlling electronic instruments that send me some data let's say every few seconds that I would like to display. I would like to be able to interract with the graph (zooming for example) without disrupting the data acquisition. I don't need super fast acquisition or refreshment rate so I would like to find the simplest way to do it, codewize.
