Yes it was only meant to get a quick view of what's going on with your
latencies. (N latency diagrams, with some addidional range and deadline stats).
Anyway I'm not that familiar with gnuplot (I know only it's basic stuff)
Does anyone think that we could create "latency-graph"-style diagrams
using gnuplot ?
I thought about separating the plotting part from the data-acquisition
part, so that one in not force to use my hackish plotting routines.
Plus by doing this separation, one can easily port the acquisition code
to RTOSes (since it makes no use of libs/syscalls (except allocation stuff)).
cheers,
Benno.
