I am animating a time series that has 3600 timesteps. I only want to plot timestep 1200 to 1800 in an animation, however I can only get the animation to run from the very first time step onwards. Below is a simplified version of what I've been trying.

sal = ax1.contourf(X[:,:,1200],Y[:,:,1200],Z[:,:,1200]),100)

def animate(i):
    sal = ax1.contourf(X[:,:,i],Y[:,:,i],Z[:,:,i]),100)

anim = FuncAnimation(f, animate, interval=100, frames=len(Seconds[1200:1800]))

The above still starts from 0. I want to be able to specify a starting index of 1200 not 0.

len(Seconds[1200:1800]) returns gives a single value 600, and according to the docs passing an int to frames is the same passing range(x). So I think your just animating just the first 600 frames. Try

anim = FuncAnimation(f, animate, interval=100, frames=range(1200,1800))

and let me know if it works!
