I have the basic Ruby gnuplot interface working. I don't seem to get the zooming feature I'm used to when using gnuplot>. Thus 2 questions: 1) How to provide the usual zooming feature when using gnuplot through ruby? 2) How to add grid lines? 3) Is there any good example documentation for someone with more ruby experience than gnuplot experience? I've already been here: http://rgplot.rubyforge.org/ Thanks, Rob -- Posted via http://www.ruby-forum.com/.
