As Doug points out, the problem is that PDL::Graphics::PLplot takes PDL objects as input rather than perl list/list-refs. If you need to use both the list ref and a PDL object you can use the pdl() constructor to make a "piddle" and the ->unpdl method to regenerate an equivalent set of list refs. >> I understand this has to do with $y.

I'm glad Doug was able to help you out. I recommend joining the perldl mailing list which is where PDL is supported and is usually the best way to get help. --Chris >> Thank you. >> Tsuyoshi Okita _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
