in reply to Plot several data set on two separate axes

You could try Chart::Clicker, which looks very flexible to me (though I've never used it myself).

I'm also sure that gnuplot can do it. Gnuplot reads plotting instructions from a text file, and data from comma or whitespace separated files, both are pretty easy to generate with Perl.

Perl 6 - links to (nearly) everything that is Perl 6.

    Gnuplot happily reads both plotting instructions and data from stdin, allowing you to just open a pipe to gnuplot and generate plots without having to create intermediate files.

      I haven't used them, but there are even (Perl) programs that are geared towards driving gnuplot for streaming data:
