       The first reason for not updating gnuplot to a newer version has been 
the fact that the older one does the job perfectly well for my applications.

       The second reason is that gnuplot is included with free download zip 
file versions of my Windows environment computer programs.  And with that 
older version of gnuplot all I had to do was include pgnuplot.exe and 
wgnuplot.exe in the zip file.  Both are relatively small.

      I went to the "help with boxes" routine first.  And the plot with 
boxes command itself is simple enough.  But getting the color part of the 
command to work properly takes some time.  I tried quite a few different 
combinations.  None did exactly what I need to have done.  And I was hoping 
that someone might remember exactly what the correct color instructions 
would be.  That doesn't appear to be the case.  So I will just keep trying 
various possibilities until one of them produces the desired result.

       The main consideration here is that whatever language is chosen, all 
of the people with whom I am working need to be willing to use it.  And the 
only language that everyone seems to like is Fortran.  I would prefer Perl 
myself.  But that isn't an option.  Some of the conversion work has already 
been done.

       Perl with PDL, Python, Matlab, various versions of Basic including 
Visual Basic, and Julia were all considered.  But one of the features of the 
language of choice is that it has to be a free download program that has a 
compiler that is easy to use.  And Silverfrost F95 with Plato is basically 
the only language that seems to meet that demand.  I could never get the PDL 
Perl module or Julia to work properly.

       Some of the Fortran people would prefer that the gfortran version be 
used.  But as far as I can tell it isn't as easy to use as Silverfrost F95 
with Plato.  Plus, once the Fortran programs are created they are easy to 
convert from one version to another.  Going from Perl to Fortran has been 
"interesting."  But that has not been anywhere near as difficult as shifting 
from GW-BASIC to Perl many years ago.

       People in the Fortran Newsgroup were asked about that "pipe" option. 
No one had an answer.  But there is another blog to check.  And one of my 
programming colleagues should have already done that.  I am mainly a 
scientist and only do programming work when no one else is willing or able 
to do the work.

       There are a number of graphics options with Fortran.  We likely won't 
be using gnuplot as the graphics package.  I wanted to know about the 
Fortran to gnuplot pipe in part because a Fortran specialist wanted the 
information.  So I thought that I would ask in this Newsgroup.
