Jan Stránský proposed the following answer:
> Why does this happen?
> ValueError: max() arg is an empty sequence

this means, that the argument of max function is empty. Try in Python: max([]).
max is used in this line:
xtremum = max(abs(s) for s in plot.data['s'])
meaning that at the time you call it, plot.data['s'] is empty.
You can have some checking beforehand or try-except construction to prevent the error.

Cheers
Jan
