Hello everyone,
Are there any suggestions about tools I could use to plot a two-dimensional array?
Thank you,
Todd
plot an array in which way?
I'm visualizing an histogram as a 'wto dimensional array', but
probably I'm just dumb and can't see what you mean 
Have you looked at RMagick and SVG::Graph ?

Check the RAA; there are a number of options. My own project charts

If you are looking for a complete scientific framework you
may want to have a look at ROOT:
It has Python and Ruby bindings. I have done the latter.

Use a pipe or the R-ruby bindings.

Hello Armin,
Thanks for RMagick suggestion. It looks very useful. I am getting
some errors trying to use it however.
After successfully installing in on my Windows 2000 machine, I type
the following:
require 'RMagick'
And, I get the output:
c:/ruby/lib/ruby/gems/1.8/gems/RMagick-win32-1.5.0-mswin32/lib/RMagick.rb:5:
uninitialized constant Magick (NameError)
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:54:in `require'

from c:/ruby/lib/ruby/site_ruby/1.8/RMagick.rb:11
from 010.rbw:1:in `require'
from 010.rbw:1
Exit code: 1
The line that the error refers to is:
images = Magick::ImageList.new("images/Button_A.gif",
"images/Button_B.gif", "images/Button_C.gif")
Any suggestions how I can fix this?
Thank you again!

I am using Windows 2000... :~( I have looked through this site
however I can't figure out how to use SVG::Graph with Windows 2000?
Do you that any pointers as to what I am doing wrong?
Thank you,

Gnuplot is nice, too. The latest version has 3d plotting with interactive rotation, zoom, etc.

Todd,
I don't understand why this is happening. What script are you running?
Is it one of the RMagick sample programs? Can you get any script that
uses RMagick to work? Try this simple test - does it work?
ruby -r RMagick -e'p Magick::Long_version'

Tim,
I get an identical error. I can't run any script that uses (require
'RMagick'), however it said that it installed 1.5 O.K. I am using
Windows 2000

Allow me to barge in... The 1.5.0 binary gem release is quite new and
you might actually be the first trying to really put it to use on a
windows 2k machine.
Can you verify the following:
a) Can you
~ require 'rubygems'
~ require_gem 'RMagick'
~ from irb ?
b) Does your gem installation look ok ? RMagick.so and RMagick.rb there,
another RMagick.rb in your site_ruby path ?
Your error looks like the shared object is not loaded at all. If you
hang in there, I would like to help you get this running.

Kaspar,
I am quite the novice to ruby however, I'm willing to try to get this
code running. I have no idea what might be important so I have just
copy a bunch of things into here. Story for the multitude.
Let me tell you what I believe I have done up to this point.

Hello Todd,
type-windows.mgk and RMagick.rb don't match the original files from the
gem. The first mismatch is ok, that file gets modified on your system
with your Font files (in postinstall procedure). The second mismatch is
weird; Could you send that file to my private adress ? I will have a
look at how it mismatches.
Have you executed postinstall ? You did not mention that.
Otherwise I am still puzzled..

I did execute postintall.rb. Sorry for not mentioning that.
The result was:

all done.

I'll send you RMagick.rb to your private address soon.
When I type and names of the files you mentioned I get the following output.
