Thanks!  It was something stupid, after all!

Now, if I could only figure out why I am continuously hit with errors like 
this:

"generated-chart-code.gp", line 72: all points y value undefined!

This is probably beyond this mailing list, but with Perl, I wrote a program 
(because of this error) that checks for any column who's y-values consist 
solely of only undefined values - and then I don't include those columns in 
the GNUplot control file.  Yet GNUplot still complains.

Do I misunderstand this error?  Why does it pop up?

The Perl can be found here, for whoever's curious:
http://www.beefstew.net/downloads/chart-unit-process.pl

I run it on the dataset linked in the previous email (although my private copy 
has column headers that I've stripped out in the public version).

Thank you, again, Juergen.
