Hi guys i am pretty much a newbie to rails and tried to install gruff and run the example given in home page for gruff i am using ubuntu and dapper.
first i got two errors when i used this example #!/usr/bin/ruby
require ‘rubygems’ require ‘gruff’ g = Gruff::Line.new g.title = “My Graph” g.data(“Apples”, [1, 2, 3, 4, 4, 3]) g.data(“Oranges”, [4, 8, 7, 9, 8, 9]) g.data (“Watermelon”, [2, 3, 1, 5, 6, 8]) g.data(“Peaches”, [9, 9, 10, 8, 7, 9]) g.labels = {0 => ‘2003’, 2 => ‘2004’, 4 => ‘2005’} g.write(‘my_fruity_graph.png’)
when i replaced require ‘gruff’ with require_gem ‘gruff’ i got rid of one but still this unintialized name error keeps poppoin when i just run it with ruby
ruby gruff.rb gruff.rb:4: uninitialized constant Gruff (NameError)
Could u guys plese tell me what i am doing wrong.
thanks prem
