     ::

RETURN
     Void

KEY
     String

VALUE
     Object

   * `key' は "gnuplot.callingMethod" または "plot.gnuplotexec".

        Use the old method to communicate with gnuplot (version 3).
        This method does not use mkfifo, but we need a patched version of gnuplot.
     [273] gnuplot.setenv("gnuplot.callingMethod",0);
     [274] gnuplot.setenv("plot.gnuplotexec",getenv("OpenXM_HOME")+"/bin/gnuplot4ox");

        Calling your own gnuplot binary.
     [274] gnuplot.setenv("plot.gnuplotexec","/cygdrive/c/program files/gnuplot/pgnuplot.exe");
