Hi,
what about opening-closing the file every now and then, for example every
5seconds?
you can do it using the function time(). It gives you the amount of time
since I don't kno when,
but you can count how many seconds are left using:
a=time()
while 1:
b=time()
left= b-a
if left == 5sec:
updating plot
Actually is very cpu consuming, but it is the best I can propose :(
