[Gnuplot-py-users] plotting problem

[Nate G. <gel...@tr...>]

Hello,

I've written a python script that collects memory data from many
test machines and graphs it over time.

I have a problem that comes & goes where gnuplot is passed a list
of /tmp/@files to plot (8 lines per graph), and it can't find the last
file. Below is a log that illustrates the issue:

I assume something is being cleaned up too quickly..

any suggestions?

thanx
nate
