[rrd-users] Counter resets - how to handle?

I am sampling a counter inside a software process (operations count)
and plotting the result over time as a graph.
I am using type COUNTER - since this is what it is.
All works well until for some reason the process has to be restarted.
At that point rrdtool assumes that the counter overflowed, and shows a
huge number of operations.
In itself, that isn't something that I am too worried about, its an
artifact of the restart and we just live with it.
The big problem is that the Y scale of the graph now zooms out to
several hundred million, so the normal operation values, in the hundreds
to thousands is lost at the bottom of the graph - at least until the
"spike" drops off the end of the window.
Any suggestions on how to deal with this?
