Matplotlib animating multiple lines and text

Question

Thanks for taking time to read my question, first time I have posted on SO so here goes...

I am plotting time series data in an animation using matplotlib.animation.

Answer 1

def animate(i):
    timetext.set_text(i)
    x = numpy.array(range(1,npdata.shape[0]+1))
    for lnum,line in enumerate(lines):
        line.set_data(x,npdata[:,plotlays[lnum]-1,i])
    return lines, timetext # <- returns a tuple of form (list, artist)

change this to

     return tuple(lines) + (timetext,)

or something similar so that you return an iterable of artists from animate.
