The idioms in the examples/animations dir should be directly portable to an embedded gtk app, eg simple_anim_gtk.py, dynamic_image_gtkagg.py, etc. You will need to either use an idle handle, a timeout handler, or a special event in the gtk event handling framework to trigger an update to the data and draw. You can extend the gobject signals to handle custom events (eg data arrives) if you want to go this route, but since you are trying to illustrate mpl more than gtk (I assume) you may want to go the easy route and use the timeout or idle handler and just check and see if new data has arrived and then update as necessary. > > PS: if there's someone that knows how to gather cpu percentage usage > on a linux sys, please tell me :) It seems not that easy to find it > out from google ;) http://tinyurl.com/d7lkga Sorry :-) Couldn't resist (less obnoxious answer http://www.cyberciti.biz/tips/how-do-i-find-out-linux-cpu-utilization.html) JDH ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
