That's very strange.  It sounds like you have an older version of
Chart-Graph installed.  What's the $Id$ line from the top
of your /usr/local/lib/perl5/site_perl/5.6.0/Chart/Graph/Gnuplot.pm
file?

As a side note, some versions of gnuplot don't plot that 3rd graph
correctly, but that's a different problem from what you're seeing.
