Hi Alan, Jerry, PLplot list. I just started updating the perl/PDL examples for plplot and have run into a question.
I updated x02.pl to clean it up and add the second plot that was missing (I have not checked anything into SVN yet). In order to make this work, I also had to update the PDL::Graphics::PLplot driver, which is part of the PDL distribution to add interfaces for some plplot routines not included before. A new PDL version is not likely to be forthcoming for a while, at least several months, perhaps a year. I also maintain a stand-alone version of PDL::Graphics::PLplot on CPAN, so I could put the required interface changes there. My question is this: Would it be better to have complete perl/PDL examples which depend upon an external PDL module from CPAN, or would it be better to have incomplete examples that are compatible with the latest PDL release?
