So it seems that the line (or area) to be dran in your graph sends
cairo over the edge ... rrdtool always creates a single path or a
single area for each LINE or AREA instruction ... the AREAs become
especially complex when they are stacked, as they then have a
jagged outline at the top as well as at the bottom.
