Hi Blaine,
It has been a while since I've used it, but I think IDL could handle
the problem, including graphing the results. It is a very powerful
system and I believe its programs can be run on the cron table, or
under a shell program which could monitor your data files and execute
the analysis whenever they have been updated. For that matter one
could write the analysis program in some high level language like C,
and do the graphics however you like (GRADS is another choice for the
graphics end) and put the whole thing under control of a shell program.
In principle what you want is not difficult.
Regards,
Russell Martin
