   Hi,

   this is more a question than an issue but I cannot fine anything anywhere
   about it. I want the dataset to be read from a file with two columns. I
   just do:

   plot.data << Gnuplot::DataSet.new("file.dat")

   but it seems not to work since it complains when running:

    line 0: undefined variable: data
   

   What should I do to use a data file as input?

   Thanks,
   Juanpe.

   That was the first thing I did but it gave this error so I thought that I could not use it:

   gnuplot> plot /Users/juanpe/code/gnuplot/data/avg_charge_t_499.dat
                 ^
            line 0: invalid expression
   

   So it took the string but gnuplot complais about it. This is what I did to have this:

   plot.data << Gnuplot::DataSet.new(File.expand_path("data/avg_charge_t_499.dat"))
