I need to have a plot window hang around and be occasionally updated by
my script as it does things. I've been looking through examples and have
not been able to get anything to work.
My current approach, inspired by strip_chart_demo.py and others in the
animation examples, is:
import gobject, matplotlib, sys
matplotlib.use('GTKAgg')
import matplotlib.pylab as pylab
import threading, time, random
class PylabThread(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
def update(self):
pylab.draw()
def run(self):
gobject.idle_add(self.update)
pylab.plot([random.random() for i in xrange(1000)])
pylab.show()
if __name__ == "__main__":
p = PylabThread()
p.start()
i = 0
while True:
print i
i += 1
time.sleep(.5)
Running this, however, yields the odd behavior that you only get numbers
printed every half second (as you should) if you move the mouse (or hit
keys, or otherwise generate events) within the plot window!
What's going on, and how can I fix this?
Thanks!
