I can give that a try and I'll check the differences between the IPC of the
Graphics::GnuPlotIF and PDL:Graphics::Gnuplot to see if there is anything that
I can naively spot as important.
I tried to build the .tar.gz file from the git and it fails during make.

Sure. I've been working down the parse tree for Gnuplot. The existing module
works great for a wide variety of simple things. There is crude FITS support.
It is possible to do everything that gnuplot can do (which is quite a lot), but
edgier cases still require messing with the syntax a bit (e.g. "xrange" works
as advertised [you pass in a list ref containing <min>,<max>], unless you set
"xmdate" to plot time values on the X axis, in which case you have to manually
pass in a string that contains double quotes -- but that will be fixed).
As for Windows support, I find that the "x11" device works fine with the only
Windows system I use. Someone else who knows (or cares) how to support the
cra^H^H^Hstuff that comes out of Redmond can hack the 2-3 methods that do the
actual IPC to the gnuplot process.
Here's an example plot I made recently for a paper. It shows fields of view of
several instruments on the STEREO-A spacecraft and locations of several CMEs
that were tracked at the end of 2008. It was surprisingly easy to generate
(and is just one frame in a movie).
I'd like to get one or two more rounds of smartening finished up and a better
test suite written, but I (and I think Dima) am planning to have a CPAN release
of PDL::Graphics::Gnuplot buttoned up in time for folks to poke and prod it
before 2.4.11 comes out (hopefully ~4-6 months after 2.4.10).
Cheers,
Craig
