Yeah, some of the examples have problems (and certainly aren't
complete by themselves).  I'll try to move updating them and getting
a new release up on the priority list some.  We have a lot of internal
updates to the code since the last release.

I think the biggest problem with example 1 is that there is a missing
close brace and comma between the global options and the
datasets.  ie, there should be something like:

           "extra_opts" => "set key left top Left",
	  },
          [{"title" => "data1",
