  I'm still waiting for the test case I require.

  Generally, think that it is always very difficult to have an idea of a
problem if there is not a test file given, reduced as possible to the strict
problem. Without it, and preferably the log file to check the various versions 
of the packages you used, you have few chance to see the problem solved, if it
is not one already mentioned and corrected.

  Concerning gnuplot, I had also some limitation memory with the LaTeX, eepic, 
PSTricks driver when I used them. Often, only the PostScript driver can be
used for huge graphics. But it depend also of your TeX engine. Some can manage
rather huge memory. And with web2c 7.n, situation will be better.
