well it was obvious to me when I wrote it. ;)
I've always said the biggest problem with a one person project is you can
only discuss this stuff with yourself and you usually think it makes sense.

that should have worked. according to help I see this:
*Plots By Names*
There are a number of additional plots that are available to you that are
simply too numerous, and less common, to list on the main page. To see a
complete list of these click on the associated *Help* button. You may enter
one or more of these and they will be produced in addition to those that
may have been selected elsewhere.
but it doesn't say they can be comma separated, which they can be. did you
include spaces AND commas by any chance?

exactly OR better still, you could create your own file, call it jeff.defs
and stick it in /usr/share/collect. It will be loaded on top of
colplotlib.defs, making it easy to preserve your settings even if you
install a newer version of colplot.
ever hear the saying "software was hard to write it should be hard to
understand?" ;) just doing my part... ;(

I do know the folks at PNNL have developed a 3-d plotting capability for
their 2300 node cluster which they monitor with collectl, send the data to
ganglia for distribution and then store in a flat file that their plotting
tool reads.
