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)


./gruff.rb:4: uninitialized constant Gruff (NameError)
