NameError - Scruffy and Gruff -

[Ams Lone]

I am trying to generate some charts using Scruffy or Gruff.. But both of
them are failing with NameError.

I am a noob and googled a lot. Any help on how to fix these errors.

D:/Screener/Scruffy.rb:2: uninitialized constant Scruffy (NameError)

Posting code is better,
but make sure you use

require 'rubygems'
require 'gemname'

(where gemname is scruffy or whatever gem you are using)


Also make sure you install a gem using
gem install gemname --include-dependencies

So you can make sure you are not missing anything.

Hey John - I reinstalled scruffy using the include dependencies option,
but still the same error..

require 'rubygems'
require 'scruffy'

graph = Scruffy::Graph.new
graph.title = "Comparative Agent Performance"
graph.value_formatter = Scruffy::Formatters:ercentage.newprecision
=> 0)
graph.add :stacked do |stacked|
stacked.add :bar, 'Jack', [30, 60, 49, 29, 100, 120]
stacked.add :bar, 'Jill', [120, 240, 0, 100, 140, 20]
stacked.add :bar, 'Hill', [10, 10, 90, 20, 40, 10]
end
graph.point_markers = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun']

ruby Scruffy.rb

Don't name your script scruffy.rb. Ruby will always look in the current
directory first for files to require. You are requiring your own script
file
by accident.

Actually it won't. "." is in $: the last entry.
