It's been a long time since 5.3.1, but as far as I can recall example 14
(which uses streams) worked then.  I suggest you try that example to make
sure it works, then compare its code with what you are doing with streams.

BTW, I suggest you take control of your own destiny and build and install
the latest version of PLplot (currently 5.7.4) for yourself on both your
systems.  That version is a lot less buggy than 5.3.1, and it also has a lot
more features.  Just follow the directions at
http://www.miscdebris.net/plplot_wiki/ .  It's one of those deals which are
"easy when you know how".  So there is some learning involved, but that is
positive because there are some fundamental software skills (like learning
to use cmake to configure the PLplot build and install) you will be
developing that will help you for other projects as well.

If you do decide to take my advice on building PLplot for yourself, then I
further suggest you clearly separate the source directory (where you unpack
the tarball), the build directory (where you do the build with the cmake and
make commands), and the install directory (where the results of running
"make install" are stored). The install directory is specified at cmake
time with the the installation prefix that you supply.  It should be a
unique directory that belongs to your user account and which is used for
nothing else than PLplot installations. That way, you can remove that
directory any time you like (say in preparation for another PLplot install),
and your PLplot installation is unique and does not interfere with anything
else including your system version of PLplot.

If you have any questions about configuring, building, and installing PLplot
using our cmake-based build system, this is the right place to ask.
