Subject: Ruport GraphReport

this is rather a followup from my other post...in the attempt to try and
graph a quick sample data i get richeous errors lol.

require 'rubygems'
require 'ruport'
require 'ruport/util'
require 'tempfile'

class GraphReport < Ruport::Report

        renders_as_graph
isp1r = []
isp1 = Tempfile.new('tempisp')
isp1.puts File.readlines('maindata.csv').grep(/Blah1/)
isp1.each do |row|
 isp1r << row["AVERAGE"]
isp1.close


def generate
 graph = Ruport::Graph(:column_names =>
%w[24,23,22,21,20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,0])
 graph.add_line [isp1r], :name => "Blah1"
 graph.add_line [14,54,22,54,12], :name => "bar" # Just an extra line,no
reason
 return graph
end
end
end

puts GraphReport.generate{|r| r.save_as("filename.svg")}


######

theoretically this should have generated 2 lines, 0 - 24 on the bottom
of the graph, and the Blah1 grep data up the side.

instead i get some awesome errors
