comment How to order lexicographically the monomers of a parametrized polynomial?
OK, now I see what's going on: the output of the original expression I posted does not reflect the internal ordering.

comment How to order lexicographically the monomers of a parametrized polynomial?
Sorry, unfortunately, since my last comment I discovered some serious problems with this approach. I describe them in an EDIT to my post.

@chuy: thanks! (I was thrown off by the fact that the docs describe ParameterVariables as "an option for GroebnerBasis and PolynomialReduce.") If you care to post your comment as an answer, I'll be glad to accept it as such.

Thanks! Switching to ListLinePlot made a huge difference. Please post your comment so that I can accept it.

comment How to embed graphic-element-specific metadata within a Graphics object?
@rm-rf: also, the Mathematica approach is far more specific than the approach I had in mind, namely, to associate metadata with individual elements, irrespective of whether the downstream use of it is based on tooltips or anything else. For example, a different interactive functionality would be one that lights up certain points depending on their associated metadata. This has nothing to do with tooltips. (I've added this example to my post.)

@rm-rf: what's orthogonal is the idea of wrapping the object (line, point, whatever) in the metadata, whereas my first instinct would have made it a property of the object...

@belisarius: thanks, that's what I was looking for. Mathematica's way of doing this sort of thing is, as usual, orthogonal to the first approach that comes to my mind, but it is always interesting...
