In short, it doesn't use PLplot or PGPLOT, and it doesn't try to mimic them.
PDL::Graphics::Prima aims to be fast, extensible, cross-platform, and
interactive. As a bonus, hard-copy figure creation is also on their way.
It sounds very exciting, but not having a hard-copy figure creation
means that Prima is a non-starter for me. I need scripts to reliably
produce ps vectorized figures, screen caps of a display won't work in
the publications I submit to. I am interested in trying Prima out
though... what are the timelines for Prima having this capability?
I'm hoping the PDL::Graphics::Gnuplot development will
be successful to provide that alternative.
I would like to point out that if PDL is to become a
usable tool for non-perl/C/unix gurus, we must provide
a stable user interface---which means supporting older
features so previous code *doesn't* break.
An example of this is the PGPLOT and PLplot graphics
libraries. I already have in mind a way forward for
both by implementing an interactive OpenGL device
driver, probably using Prima as the widget set. With
this capability, any PGPLOT or PLplot image could be
embedded, converted, exchanged, transformed for any
other module that could handle the basic image format
such as RGBA.
Notice that this approach means that existing PGPLOT
and PLplot users can keep going with their current
skillset *and* that they can make use of the new,
more portable, more robust frameworks being planned.
