Re: [Matplotlib-users] Plot data from file while is file is constantly updated

[francesco o. <fra...@gm...>]

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 :(
