sending data to second python script

[Cyberfly]

I stripped some unnecessary stuff from the example to make it easier to follow. I will have another look at whether it can be stripped down even more (the tornado and thread stuff), but I tested it like this and it runs from my pi (which is good).

import random
from time import sleep, time
from tornado import gen
from functools import partial
from concurrent.futures import ThreadPoolExecutor
from threading import Lock, Thread

from bokeh.layouts import column
from bokeh.models import ColumnDataSource
from bokeh.document import without_document_lock
from bokeh.plotting import figure, curdoc

t0=time()

executor = ThreadPoolExecutor(max_workers=2)
doc = curdoc()
@gen.coroutine
def update_data(x,y1,y2):
	new_data=dict(t = [x], tarTemp = [y1], temp = [y2])
	data.stream(new_data, 10000)


@gen.coroutine
@without_document_lock
def main():
	while True:
		doc.add_next_tick_callback(partial(update_data, x=time()-t0, y1=random.randint(0,100), y2=random.randint(0,100)))
		sleep(1)


data=ColumnDataSource(dict(t=[], tarTemp=[], temp=[]))
fig=figure(logo=None)
fig.xaxis.axis_label = 'Time (s)'
fig.line(source=data, x='t', y='tarTemp', line_width=2, alpha=.85, color='pink')
fig.line(source=data, x='t', y='temp', line_width=2, alpha=.85, color='purple')


doc.add_root(fig)
thread = Thread(target=main)
thread.start()
