Thank you. That is a great idea and it works!

2 questions:

1. I see that your send method on plot.send is a method from 
Gnuplot::Plot.new but what exactly is it doing? My guess is it takes 
'val' and sends it to the plot method that corresponds with 'opt' as it 
iterates through my hash.

2. How do I apply your idea to methods within an embedded array block 
such as "plot.data" from my code:

  plot.data << Gnuplot::DataSet.new( [x, y] ) do |ds|
    ds.with = "lines"
  end

which has methods such as ds.linewidth, ds.title, etc? I tried multiple 
things like creating 2 hashes but can't get my hash values to pass into 
the embedded array. Thank you!
