They look pretty I suppose, but it also looks like I've got the vrules 
botched somehow.  Though I cannot find the bug just yet in the 
repository copy.  The red vertical line should be at the start of the 
UDP_STREAM test's results, and there should be a black one right after. 
  They shouldn't be at the ends of the _RR test.  Did you tweak that bit 
when you converted to a UDP_STREAM test?

The other thing is it appears the scaling to make rrdtool look like it 
supports dual y-axes could use a bit of tweaking.  I was pretty much 
guessing there :(
