Read DataSet from file

[AAraKKe]

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.

full input file?

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"))

so it does work with the expand_path snippet?
