Postscript files generated by graph

[Niels Möller]

I'm having some trouble with the graph program. It generates
a postscript file that appears to be broken. gs-6.52 complains

I create the postscript file with the command

        graph -T ps -y 0 4 -X n -Y Delay -w 0.7 -h 0.3 \
        -m2 delay-min.plot -Ie -m1 delay-total.plot >delay-graph.eps

I'm attaching a tarfile with the (pretty small) input and output
files. graph --version says "graph (GNU plotutils) 2.4.1". I don't
read postscript well enough to understand if this is plotutil's or
ghostscript's fault.
