Subject: Re: FasterCSV, Gruff and Large Data Import

Not really, well I could but I'm trying to compare it with doing it in a
similar program such as GNU Plot, plus there are sometimes
irregularities in the data which I'd like to show if possible. 

On a second look the error I'm getting is a gruff related one. 

c:/ruby/lib/ruby/gems/1.8/gems/gruff-0.3.4/lib/gruff/base.rb:943:in
`larger_than
_max?': undefined method `>' for ["1\t8877"]:Array (NoMethodError)

line 20's where the array gets pushed into the graph.

Well, I think you probably need to trim the data down a bit.  Could  
you maybe build up some averages over time periods and feed just those  
averages to Gruff?
