      OK, I got break processing figured out :)

      Now, how do I deal with the case where I'm given a table with an X field and an arbitrary number of (named) Y fields? I think I just need some hints to get started.

      For example, I have a table of 5-minute system load averages from a set of Linux systems, and the size of this set may/will vary for each different report run:

      1264527900,"2010-01-26 09:45:00 PST",1.53e+02,1.35e+02,1.22e+02,1.39e+02,2.34e+02,

      I need to create, first, a scatter plot and include a legend giving the column (device) names.

      What are the key words/concepts I need to look into? I *suppose* I could do some trivial pre-processing to set an environment variable to the table width, if necessary.
