Combination of GNU plotutils and Ruby/GSL.

Nice link, but a little out of date. An updated version (2.2) is available
here:

Ok, I should have mentioned that I am using windows. I tried
ruby/gnuplot but it doesn't seam to work with windows. The problem
seams to be with the instantiation of a new Gnuplot process. From the
project webpage:
"Gnuplot.open
Instantiates a new Gnuplot process. The path to the executable is
determined on a Unix or MacOSX system using the which command. Windows
users, I have no idea what to do. If a block is given to the function
the opened process is passed into the block. This mimics the most common
usage of the File.open method. "
Any idea how to get this working on windows? Or should I be using a
different graphing package?

Still not working, same problem with the .open method. I'll run through
my steps for installing gnuplot and ruby/gnuplot:
gnuplot - downloaded gp400win32.zip from gnuplot website. Unzipped
files and stored in C:\Gnuplot. There were two executable files,
pgnuplot.exe and wgnuplot.exe. I renamed pgnuplot.exe to gnuplot.exe.
ruby/gnuplot - used gem install. Then set path variable in both user
variables and system variables to C:\Gnuplot. Also created RB_GNUPLOT
in system variables and set it to C:\Gnuplot\gnuplot.exe. Still doesn't
work. I then tried to hardcode the path in the gnuplot.rb. Altered
line 22 "path = ENV['PATH'] # || ENV['WHAT_EVER_WINDOWS_PATH_VAR_IS']"
to "path = 'C:\Gnuplot'". Also tried to add the gnuplot.exe. Still
doesn't work.
What am I doing wrong?

i'm not sure and not at a windows box attm. i'll try to look at this in a
bit. hopefully someone else will chime in before then though...
regards.

ok, thanks. Just in case it helps, part of the error I get is that the
'+' is an undefined method in gnuplot.rb line 45.

I've made a bit of progress. On line 46 of the gnuplot.rb, I changed:
cmd += " -persist" if persist to :
cmd = "C:\\Gnuplot\\gnuplot.exe" + " -persist" if persist
The graph pops up for a very brief period and then terminates. The
program is the sine wave example from the ruby/gnuplot home page how to.
It appears as if the pesist flag is not working correctly, but I'm not
sure how to fix this.
