Linux is fully supported provided that the PERL GD package, the PERL TK package and TK/PNG are installed. These can be downloded from CPAN and built on most Linux systems.
You will need to build and install PERL GD package, the PERL TK package and TK/PNG. We have tested successfully with the following:
You may need to install libgd as part of Cygwin. Also PNG libraries. Just do a FULL install of Cygwin.
MAC OS X
Unfortunately PERL TK has not been ported to MAC OS X without X Window support. prlplot will work up to creating the plot as a GIF file. However, you cannot zoom in/out since TK is not installed. So you have to strip out TK functionality. Othewise, just install GD. You may need to download and build libgd etc. Just display the generated file "xplot.gif".
