I can't repeat the installation at the moment.
But starting gnuplot.exe, it says (Private machine, Win7, 64bit,
ASPerl 5.14.2, PDL 2.4.11):

gnuplot changed the codepage of this console from 850 to 1252 to
match the graph window. Some characters might only display
correctly
if you change the font to a non-raster type.

But With GNUPLOT 4.6 on my other machine same things happen.

Thanks to Diab, Chris, and Juergen for your prompt testing!
I've fixed Diab's and Chris's issues, and looked at Juergen's but I'm still stumped by his multiplot-freezing-up issue. I'm taking the liberty of pasting Juergen's testfile here. Does anyone else see this problem (on failure the attached testfile freezes) and/or does anyone have an idea what could possibly cause it? Juergen, if you run 'make test' again it will report your gnuplot version number, which might help.
rc2 is now up on github (below).

Hi, all,
After numerous bugfixes and much helpful multiplatform testing from Chris, Doug, and Jurgen, I've pushed a release candidate PDL::Graphics::Gnuplot 1.4 up to git. You can get it from "http://github.com/drzowie/PDL-Graphics-Gnuplot". If all goes well I will release 1.4 via CPAN in the next 48 hours.
I would greatly appreciate a quick "make test" (preferably with the environment variable GNUPLOT_INTERACTIVE set to a true value) on various
platforms, to make sure 1.4 will be stable for a while.
PDL::Graphics::Gnuplot has continued to mature and most of the recent bugfixes have been to address multiplatform issues.
While there are several important (and some obscure) interface bugs fixed, 1.4's main advantage is that it handles the pipe to gnuplot more robustly - particularly in the way it handles interrupts (e.g. you banging on ^C while it is trying to get some work done).
There is good news on the gnuplot front as well: a recent patch, which I believe is now in the gnuplot CVS, speeds up image transfer by a factor of 300, so that pipe transfer time no longer dominates plot time. This means 1k x 1k monochrome images only require a small fraction of a second to display, and 2k x 2k double-precision RGB images render in about 1 second (on my 2yo MacBook Pro; YMMV). While that performance gain doesn't affect stock gnuplot installations, it should percolate through their release process in the next few months.
Happy plotting,
Craig
