step 1: Determine the maximum value for incoming and for outgoing
step 2: Use the determined values inside a HRULE

So: At the first stage you use "rrdtool graph" without graphing elements
but with a PRINT (!!!NOT!!! GPRINT!) command.  The resulting numbers are
then available to your script so you can now create the input for a next
"rrdtool graph" command, this time including the normal graphing functions
and your HRULE commands.

Much of what looks like rudeness in hacker circles is not intended to give
offence. Rather, it's the product of the direct, cut-through-the-bullshit
communications style that is natural to people who are more concerned about
solving problems than making others feel warm and fuzzy.
