http://rgplot.rubyforge.org/ is the new home for this project.
I have decided, after a couple of years of using gnuplot and ruby, that this project doesn't do anything meaningful. Ruby has such great facilities for string manipulation and IPC that this library just seems redundant.
I've uploaded a bug fix to the MatrixDataSet which fixes a problem if any of the data values are nil.
Version 0.5 has been released. This version introduces a different way of associating DataSet classes with their source classes.
I've done an update of the CVS repository. This introduces a change in the way that PlotItems are created which I think makes it easier to use gnuplot in an interactive mode.
John Swinbank has volunteered to manage debian packages for rgnuplot. The debian package for version 0.4 has been uploaded to Sourceforge
I've updated the package with some fundamental changes. To begin with, all of the ruby code has been consolidated into a single file Gnuplot.rb. I've also updated the demo.rb and gotten rid of some files.
It looks like I've figured out the CVS repository. It now contains the most up to date version of RubyGnuplot and will continue to be updated as I work on it.
I'm having problems working with the CVS repository up here on sourceforge. Because of this, the code for 0.3 is NOT in CVS. I'm working on this and will post a message as soon as it is fixed.
