Please help me to figure why ruby is throwing following error.....

following is my code.
----------------------------
#!/usr/bin/ruby
require 'procStartupTimes'
require 'rubygems'
require 'gruff'

g = Gruff::Line.new
g.title = "My Graph"

a = [1, 2, 3, 4, 4, 3,2, 3, 1, 5]

g.data("Apples", a)

puts a.size

inc = 2

x = Hash.new(a.size/inc)
x[0] = a.first.to_s
x[a.size/inc] = a.last.to_s

for i in 1..((a.size/inc)-1) do
  x[inc*i] = a[inc*i].to_s
end

puts x.inspect

g.labels = x
g.write('my_fruity_graph.png')

------------------------

it throws below error...could someone pls tell me what causes this?
