thanks, it is exactly what I need... I have undestood the logic, I build a plot, put my traits values into an array and then I call the add_current_state_to_plot function to update the plot with the new values...
I am an absolute beginner of matplotlib, can you give me a little example of add_current_state_to_plot function? Because I don't know the right way to update: do I have to pass all the array, or just the new values? best regards, simone 2009/1/18 C Lewis <chle...@nature.berkeley.edu>: > Guessing about what you want: > > Does the class change with time? that is, perhaps you have a class foo, and > foo evolves, and you would like to plot a history of some traits of foo, but > at any given moment foo only contains its current state? > > If so, I think you need to have a function in foo, or even a separate class, > that takes `snapshots' of foo's traits on one schedule, and stores them, and > can also plot them on some schedule.
