No. Not certain how that could even be implemented; however,
some restrictive INTERVAL definition might be feasible. I'll take it
under advisement.

Not yet. I'll add that to the list. Maybe something like LEGEND=(x,y)

No. At present DBD::Chart simply interpolates thru NULL pts.
Not certain how to handle that "heuristically"; however, the app can
provide that by treating the discontinuity as a separate graph (ie,
supply the first batch of pts as one graph, and the next batch as a 2nd
graph. etc.)
One other point: I suspect the folks on this list may not consider
this truly "on topic" (in fact some consider the whole concept
of DBD::Chart/DBIx::Chart absurd 8^),
so if you have further questions, either contact me offlist
directly, or use the c.l.p.modules newsgroup (which I monitor).
