Updating quiver arrows in animation

Hi,

I have a plot that includes arrows drawn by the quiver command. I would like to create animation using Func Animation, but I don't know how to update the quiver arrows. I can update everything else on the plot and animates fine.

Does anybody know how to update the quiver arrows in an animation? I know the quiver arrows have a XY property, but changing that doesn't update the plot.

Thanks!

You cannot update the arrow positions without making a new Quiver instance, so to animate with varying positions, you will need to delete the previous Quiver instance and make a new one for each frame.

Given this, it might be best to use ArtistAnimation then, which should
handle turning on and off artists that you provide as a list of list
of artists.
