We use RRDTool for our graphing (with 14all.cgi to produce the pages). 
With RRDTool, you could generate a graph and put a horizontal line at the
CIR and use Maxbytes set to 128K.  If you wanted your 'dwmy' graphs to
show the line, you would need to edit 14all.cgi (or whatever you would
decide to use) by adding the HRULE parameter (part of: RRDs::graph).
If this sounds like something you might want to try, you may want to
download RRDTool (www.rrdtool.org) and read through the documentation, or
if you're using windows, take a look at the MRTG Implementation Manual
written by Florin Prunoiu (even if you're not using windows, it might
still be somewhat helpful).  Good Luck!

Hope that helps,
