Hello,
Thanks for your help.
Do you need the colorbar scale to change with each frame? If not, you can

Yes, I do need the colour bar to update with each frame unfortunately!
What I would do is "prime the pump" by creating the first frame. Then

I see what you mean here, the problem is that while I could do it I think
it would take more memory because each frame is a composite if a few data
sets, and also I quite like the separation of the data and the animation.
Just a thought, would it be possible to combine the two, to create a list
of artists that stores the AxesImage and Line2D object I have for each
subplot and then create a FuncAnimate to add a colorbar and animate them?
Or (continuing thinking this up) to create a list of axes objects
(subplots) then add colorbars to them and just add them to a figure??

Not really sure what you mean by faster rendering in this context, surely
the rendering done when you draw the Artist in ArtistAnimate is the same
speed as drawing out of a FuncAnimate?

What the size of the domain or the Vlim's??
Thanks again
