... Jan> Is there any better way to do this easily? Set a timeout. How to do that depends on what gui tools you are using. I've never used pylab so I don't know how it integrates with the rest of your app. If you're using PyGTK, something like this should suffice: gobject.timeout_add(5000, update_plot) where the update_plot function executes your acquisition/plot code. It needs to return True if you want it to be triggered every five seconds, otherwise it's a one-shot. Skip -- http://mail.python.org/mailman/listinfo/python-list
