NMIS had this a million years ago.

(ref. https://sins.com.au/nmis/ the precursor to what the Opmantek guys have now)

their back end was all perl and RRDtool

fwiw.

This isn't something that can be easily added because of how graphs are generated.

It's trivial with a graphing system that supports it and next to impossible with one that doesn't.

Since we use RRDtool as our metric storage system, we don't have efficient direct access to the data and rely on RRDtool itself to generate the images.
