My own investigation into the graphviz source seems to indicate that lib/common/output.c is probably where this bug is located. That file contains the dot output code, and is where the '-y' vertical flip is implemented which would explain why only dot output is affected. It seems that all co-ordinates output undergo a translation and possible vertical flip when written out from that code. Since 2.6.23, it also looks like the file was completely modified to use a different units when working with co-ordinates, I guess that's when this bug was introduced. > I'm not at all familiar with monotone-viz ... does it render the > resulting dot file itself rather that asking dot to do it? Yes, it renders the dot file itself. It needs dot's output so it can handle things like the user selecting various graph nodes. > Anyway, I'll pass your report upstream, together with the results of my > investigations. Ah, I already submitted a bug report (which I should have mentioned), although all it contained was the input dot and broken output dot files. Unfortunately, there doesn't appear to be a sane bugtracker there so I couldn't provide a reference to the upstream bug report.
