However if I feed the fastercsv data into an array then into gruff it
_should_ work, as feeding a whole array that I've written out by hand
into gruff works. If you see my logic here, it should work, no?

Looks like you're feeding the whole CSV table into Gruff all at once.
Try
something like this:

idx = 1
FasterCSV.foreach("r.csv") do |row|
  g.data("Series #{idx}", row)
  idx += 1
end
