To answer my own question, in case anyone else is interested, here is a 
block of code that can be substituted for the corresponding elements of 
the embedding_in_webagg.py example. The whole block goes at the bottom.
-------------------------------------------------
def create_figure():
 fig = Figure()
 ax = fig.add_subplot(1,1,1)
 ax.set_xlim(0, 1)
 ax.set_ylim(0, 1)
 line, = ax.plot([], [], 'r-')
 return fig, line
if __name__ == "__main__":
 figure, line = create_figure()
 application = MyApplication(figure)
 http_server = tornado.httpserver.HTTPServer(application)
 http_server.listen(8080)
 print("http://127.0.0.1:8080/")
 print("Press Ctrl+C to quit")
 def update2():
 line.set_data(np.random.rand(2, 25))
 figure.canvas.draw_idle()
 io_loop = tornado.ioloop.IOLoop.instance()
 cb = tornado.ioloop.PeriodicCallback(update2, 1000)
 cb.start()
 io_loop.start()
----------------------------------------------------------
Instead of the using the PeriodicCallback I will probably be using 
ZMQStream.on_recv() to register a callback on a socket, but that doesn't 
change the basic structure.
