                    GNUPLOT EXAMPLE 1

*******************************************************************************

        To enter GNUPLOT, type `gnuplot'

        Then type the following commands:

-------------------------------------------------------------------------------

set data style lines        (OR  points  OR  dots  OR  linespoints)
plot sin(x),'fort.11'

-------------------------------------------------------------------------------


  Alternatively the above lines can be entered into a file.
  These commands can then be activated on entering GNUPLOT by typing the
  load command, e.g.

		load 'filename'  

  Note that the quotes (') are necessary.

  If there is more than 1 set of data in a data-file, each set must be
  separated by a blank line.

  The above commands display the graph on the screen. For a hardcopy,
  type the following commands before exiting GNUPLOT:

                      set term postscript
                      set output 'mygraph.ps'
                      replot

   Then type `q' to exit GNUPLOT.

   Now `mygraph.ps' can be sent to the postscript printer.

   NOTE: the `.ps' extension is not necessary but it will help distinguish 
   between postscript and non-postscript files.

-------------------------------------------------------------------------------

                             BUGS

  Numbers appearing in data-files written with the double precision format
  will be read incorrectly by GNUPLOT.  e.g. 0.34223D-01, will be read as
  0.34223. Hence avoid formatting output in this style.

                             HELP

   Gnuplot has a very effective on-line help facility. Type `help' and follow
   the instructions.
