Ah, I had forgotten about that.  For me, it was much easier to just 
switch over to RRDTool where you can do that kind of stuff right 
out of the box...

That's almost correct.  mrtg in it's native form has a third line called
dorelpercent, it shows in/out.  You could try to modify the formula in
rateup.c (around line 525) to make it (outr+inr)/maxvalue*100, and then
recompile.  I tried to do this but I couldn't figure out what variable had
the maxvalue. 

Please let me know if you figure it out,
