Subject: plot3d does not accept an arrayref as its first data argument
The documentation indicates that arrayrefs[*] are acceptable as data arguments. It looks like that's not quite the case for the first argument to plot3d Show quoted text
pdl> plot3d( [0],[0],[0] )
term is wxt Runtime error: Can't call method "ndims" on unblessed reference at /proj/axaf/ots/pkgs/perl-5.16/x86_64-linux_debian-6.0/lib/site_perl/5.16.3/PDL/Graphics/Gnuplot.pm line 3209, <DATA> line 90. Show quoted text

[*] The documentation actually uses the term "listref", but technically there's no such thing in Perl. There are lists, by they are ephemeral and you can't take a reference to them. "listref" should be replaced by "arrayref".
