I'm sure you're welcome to build this into RRDtool. I think this will
prove to be a relatively easy task, so good to start with.
Next problem to solve:
How to display bitfields 65536 some 100+ times, bitfield 128 also some
100+ times, and bitfields 32768, 16384, 8192 and so on each one time. All
of this for a single pixel column, the next pixel column has a similar
problem with different amounts, and data still need to be visible,
readable, understandable. Basically you need to show 256 timeslots per
pixel column, without consolidating 256 rates into one rate. The pixel
column is 100 pixels high.
