[Visualpython-users] Question: Redrawing vectors

[Karim D. <kar...@sa...>]

This question may have been addressed before, but I am
new to vpython and I have not found the answer so far:
I am drawing vectors representing the magnetic field surrounding a =
moving charge but at every iteration my program draws the new vectors on =
top of the previous ones. I would like to be able to draw only the =
current vectors. Is there a way of "refreshing" the display as in Java?
I tried to tinker with the visible attribute of my vectors (trying to =
turn "visible" on and off) but it did not work.
Thanks for any pointers.
