Did you know that any widget can serve as a container for any other widget?
If you're just trying to have two widgets side-by-side, you can say
something like this:
use strict;
use warnings;
use Prima qw(Application);
use PDL::Graphics::Prima;
my $main_window = Prima::MainWindow->create(
size => [600, 300],
);
# Add the first plot
my $plot1 = $main_window->insert(Plot =>
pack => {
# Pack it into the left half of the window
anchor => 'sw', x => 0, y => 0, relheight => 1, relwidth => 0.5
},
... other initialization ...
);
my $plot2 = $main_window->insert(Plot =>
pack => {
# Pack it into the right half of the window
anchor => 'sw', relx => 0.5, y => 0, relheight => 1, relwidth => 0.5
},
... other initialization ...
);
... other code that uses $plot1 and $plot2 ...
run Prima;
__END__
There are a few ways of doing this without storing the plot widgets in
lexical variables, but I suppose that's getting a bit off-topic for the PDL
mailing list. If you want to pose the question on the Prima mailing list, I
can try to address it at greater length there.

I would love to see this happen, but I don't have the time to work on it at
the moment. (We discussed it a little bit back in February, I think, but
the Prima email archives <http://www.prima.eu.org/archives/> haven't been
refreshed in a while so I can't find the link.)
