Hi!
In Debian, there is this bug report by a user: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626984 reported also on rubyforge: http://rubyforge.org/tracker/index.php?func=detail&aid=29177&group_id=173&atid=741 proposing to transform the pipe calling the gnuplot command from write-only to read-write, so that the output of the plot could be stored in a variable.
Here is the relevant part of the patch
--- gnuplot.rb.orig 2005-11-15 03:33:42.000000000 +0100 +++ gnuplot.rb 2011-05-06 23:04:02.000000000 +0200 @@ -56,7 +56,12 @@ def Gnuplot.open( persist=true ) cmd = Gnuplot.gnuplot( persist ) or raise 'gnuplot not found' - IO::popen( cmd, "w") { |io| yield io } + IO::popen( cmd, "w+") { |io| + yield io + io.close_write + @output = io.read + } + return @output end
the rest is about adding a smooth attribute, but this has already been included. Would you consider this modification as possible?
Thanks!
Cédric
