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 :( rick
