In order to do this well, you need to use your user interface idle handler. The example I used was just to illustrate the line handling, but for real work you should set you update function in either an idle handler or a timeout handler. Look in the examples/animation directory http://matplotlib.sourceforge.net/examples/animation for different examples for each user interface (see also the animations cookbook tutorial at http://www.scipy.org/Cookbook/Matplotlib/Animations). The way to do this differs for each toolkit, and we have examples for many in the examples directory I pointed you to above. Does anyone have an example of how to do proper idle handling with tk? JDH
