-I did look your code again and there is another issue.
-You should also notice that u're calling gplt.plot recursively from
time_series(), so it will pop-up a new window every time it's called
(different scopes).
-What you could do is to plot 'just once', using a matrix. For example,
for a 2-D plot, say y(t) x t, u can store every new set of data in the
columns of matrix 't' (abscissas) and matrix 'y' (ordinates), and then
plot it ('t' and 'y' must have the same shape).
-Also, if u dont want gnuplot to flood u up, u can unset the option
'persist' (doesn't work on M$ Windows). For this u'll need to take look o
scipy/gplt/interface.py and scipy/gplt/pyPlot.py, cuz im not sure if u can
do it through gplt.
-I'm 'extending' gplt (not really, cuz it has all u need to add new
options) to use the rest of gnuplot options (like 'size ratio'). I'll
probably add something about the 'persist' flag.

-At least, is it saving correctly?
