This is a known upstream bug, the OpenGL plotting toolkits only support single precision values. If your x or y data series exceed the bit depth of single precision, some number of sequential values will end up being the same, and it will plot as you've seen. A workaround is to use gnuplot as Rafael has shown. Another workaround would be to quantize or scale your x data series so it doesn't overflow the depth of a single precision value. For example, if you subtract datenum(2010,1,1) from your trr vector, the plot comes out ok. -- mike -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
