Ruby and Gnuplot and Windows


#1

I want to combine Gnuplot support to an FXRuby application, and
unfortunately,
this always crashes with Segfault when I run it in Cygwin, which used to
be
my way of running Ruby and indeed anything on Windows…
So I tried to install the ruby gnuplot gem (v 2.2) using the gem
installer
of the one-click
installer, and tried this test file:

require ‘rubygems’
require ‘gnuplot’

Gnuplot.open do |gp|
Gnuplot::Plot.new( gp ) do |plot|

plot.xrange “[-10:10]”
plot.title “Sin Wave Example”
plot.ylabel “x”
plot.xlabel “sin(x)”

plot.data << Gnuplot::DataSet.new( “sin(x)” ) do |ds|
ds.with = “lines”
ds.linewidth = 4
end

end

end

Now, the application starts, but just doesn’t do anything - there is
no error message or warning, and no output.
Does anybody use Ruby Gnuplot and the Ruby from the one-click
installer (latest version) successfully ?

Thanks,

Best regards,

Axel
